what is the similarities of post zygotic and pre zygotic​

1. what is the similarities of post zygotic and pre zygotic​

Answer:

Reproductive isolation is a mechanism that keeps species from mating with others. Prezygotic isolation prevents the fertilization of eggs while postzygotic isolation prevents the formation of fertile offspring. ... Postzygotic mechanisms include hybrid inviability, hybrid sterility and hybrid "breakdown."

Answer:

The main difference between prezygotic and postzygotic isolation is that the prezygotic isolation acts before fertilization. But, the postzygotic isolation acts after fertilization

2. Which of the following shows the proper sequence of a developing fertilized embryo? a. embryo – zygote – fetus b. fetus – embryo – zygote c. zygote – embryo – fetus d. zygote – fetus – embryo

The answer is d, zygote - fetus - embryo.

3. 11. Which is the correct order of sexual reproduction?B.gametes, fertilization, embryo, zygoteA. fertilization, gametes, zygote, embryoD. zygote, gametes, fertilization, embryoC. gametes, embryo, fertilization, zygote​

Answer:

A.

Explanation:

Sexual reproduction consists of a set of events and can be divided into four stages: fertilization-gametes-zygote-, embryo.

4. How does a zygote change into an embryo? A. The zygate unites repeatedly to form an embryo. B. The zygote divides repeatedly to form an embryo C. The zygote divides ones to form an embryo. D. The zygote stays alive for a long period of time​

Answer:

First, the zygote becomes a solid ball of cells. Then it becomes a hollow ball of cells called a blastocyst. Inside the uterus, the blastocyst implants in the wall of the uterus, where it develops into an embryo attached to a placenta and surrounded by fluid-filled membranes.

Explanation:

5. site for the implantation of the zygote?​

The uterine lining is the the site of the implantation of the zygote.

6. It is a development of a zygote​

Embryo

Explanation:

A zygote is the union of the sperm cell and the egg cell. Also known as a fertilized ovum, the zygote begins as a single cell but divides rapidly in the days following fertilization. After this two-week period of cell division, the zygote eventually becomes an embryo. If this goes well, the embryo becomes a fetus.

9. the developed zygote is called?​

Answer:

Embryo

Explanation:

When a Zygote Becomes an Embryo

Because each cell contains half of the genetic material, each cell is known as a haploid cell. ... The embryonic period of development lasts from two weeks after conception through the eighth week, during which time the organism is known as an embryo.

10. What is the meaning of zygote?

Zygote is a fertilized egg that is basically the product of fertilization and gametogenesis ( if I'm not mistaken) and would eventually turn into an embryo, a young new formed organism.Zygote? a 1-2 weeks fertilized egg

11. A zygote is haploid.

In meiosis, four haploid daughter cells are produced. Haploid means half of the original chromosomal number and is represented as (n) while diploid are represented as (2n). For example, the total chromosomal number of humans is 46 (2n), therefore, the haploid of these is 23 (n), which is visible in human gamete formation.

Answer:

1.meiosis has two rounds of division.

ʜᴀᴘᴘʏ ꜰᴀᴄᴇ ☻Meiosis contains two separate cell divisions, meaning that one parent cell can produce four gametes (eggs in females, sperm in males). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.

2. meiosis occurs during the formation of body cells .

ꜱᴀᴅ ꜰᴀᴄᴇ☹Meiosis occurs in specialized cells of the body called germline cells.

3.zygote formed after the fertilization of the sperm and the egg cell.

ʜᴀᴘᴘʏ ꜰᴀᴄᴇ ☻A zygote, also known as a fertilized ovum or fertilized egg, is the union of a sperm cell and an egg cell.The zygote phase is brief, lasting only about four days. Around the fifth day, the mass of cells becomes known as a blastocyst.

15. what is read in zygote

zygote is the cell that forms by union of an egg cell and sperm cell

16. when is a zygote formed?

Answer:

The zygote is formed when the male gamete (sperm) and female gamete (egg) fuse.

Explanation:

I hope this helps.

Zygotic stage: The zygote is formed when the male gamete (sperm) and female gamete (egg) fuse. Blastocyst stage: The single-celled zygote begins to divide into a solid ball of cells. Then, it becomes a hollow ball of cells called a blastocyst, attaching to the lining of the mother's uterus.

24. The union of sperm cell and egg cell form a zygote why is the resulting zygote referred to as diploid.​

Answer:

[based on gogle]

The resultant cell is called a zygote. It is diploid as it has two copies of every chromosome - one came from the sperm cell and one came from the egg cell. The zygote will mature into an embryo. It has DNA from both the mother and the father so will have a mixture of characteristics from both parents.

                                              Hope it helps!

Answer :

The zygote represents the first stage in the development of a genetically unique organism. The zygote is endowed with genes from two parents, and thus it is diploid (carrying two sets of chromosomes). The joining of haploid gametes to produce a diploid zygote is a common feature in the sexual reproduction of all organisms except bacteria.

The joining of haploid gametes to produce a diploid zygote is a common feature in the sexual reproduction of all organisms except bacteria.The zygote contains all the essential factors for development, but they exist solely as an encoded set of instructions localized in the genes of chromosomes. In fact, the genes of the new zygote are not activated to produce proteins until several cell divisions into cleavage. During cleavage the relatively enormous zygote directly subdivides into many smaller cells of conventional size through the process of mitosis (ordinary cell proliferation by division). These smaller cells, called blastomeres, are suitable as early building units for the future organism.

These two masses, which are genetically identical to each other, go on to become embryos. Fraternal twins, by contrast, develop from two separate zygotes (two separate eggs fertilized by two different sperm).

25. site for implantation of the zygote?​

Answer:

Uterus

Explanation:

During fertilization, the sperm and egg unite in one of the fallopian tubes to form a zygote. Then the zygote travels down the fallopian tube, where it becomes a morula. Once it reaches the uterus, the morula becomes a blastocyst. The blastocyst then burrows into the uterine lining — a process called implantation.

29. Identical twins develop from zygote(s). Fraternal twins develop from zygote(s).

Answer:

Fraternal twins develop from

zygote(s).

Explanation:

Identical twins develop from the same zygote, hence why they are identical. Fraternal twins are not identical and therefore do not.

Identical twins develop from?

One Zygote or Monozygotic (MZ)

-Monozygotic (MZ) twins, also called identical twins, occur when a single egg cell is fertilized by a single sperm cell. The resulting zygote splits into two very early in development, leading to the formation of two separate embryos. Because these twins come from one zygote, they're also known as monozygotic. Identical twins are the same sex.

Fraternal twins develop from?

Two Zygote

Sometimes a woman's ovaries release 2 eggs, and a separate sperm fertilises each egg. This forms twins. These twins are called fraternal twins, dizygotic twins (meaning two zygotes) or non-identical twins. Fraternal twins are siblings who develop from separate eggs and separate sperm cells, but during the same fertilization period. So they end up being conceived at the same time, developing at the same time, and being born at approximately the same time.
