No, replication only takes place in the S phase of Interphase. Although, a brief interphase exists between Meiosis 1 and Meiosis 2, there is no S-phase in this case. Hence, no replication takes place between meiosis 1 and 2.
â??My Brotherâ??s Peculiar Chickenâ?? is a comedic short story by Alejandro Roces. It involves the issue of cockfighting, a popular Filipino sport. It is written in the First Person voice of the younger brother who, along with many, questions the birdâ??s gender.
No. That's not possible because chicken and duck are two different races (biological meaning). This is the same thing for a human and a monkey ! There are many reports of these crossing but most are not recent. They come from the late 1800's and early 1900's. Many times these birds will be friends and appear to mate but there has been no DNA work to prove it one way or the other.
Yes! Egg is good for chickens in moderation. You would want to cook it first though so they do not get in the habit of pecking eggs. Contrary to the previous answer... egg yolks are not baby chicks! Not all chicken eggs are fertilized. Hens lay eggs whether there is a rooster present or not; we get three eggs a day from our three ladies and no roosters are allowed in city limits. You are not eating baby chickens when you eat eggs! You can even feed your chicken...chicken!
People have 23 chromosomes in their gametes – 22 autosomes and one sex chromosome. This is the result of a process called meiosis, which halves the number of chromosomes in a cell to produce gametes with half the genetic material.
Have to say Nay. Two chromosomes are 'homologous' , to my understanding, only if each is IDENTICAL with the other - this means a pair. Gametes are haploid, meaning that only one copy of each (normally diploid or paired) chromosome (s) is (are) present.

46 in a human body cell. 23 in the sex cell e.g. sperm and egg cell (gametes) when they combine you end up with 46 again.
After the S phase of the cell cycle, there are 46 chromosomes present in the cell.
Every human being has 23 pairs of chromosome which translates into 46 chromosomes.

In meiosis, cells duplicate their chromosomes only once, during the S phase of interphase, before the process begins. This duplication results in homologous chromosomes, each consisting of two sister chromatids. The subsequent two rounds of cell division (meiosis I and meiosis II) separate these chromatids and homologous pairs, leading to the formation of four haploid gametes.
Meiosis creates gametes (sperm and ova/eggs) which are involved in sexual reproduction. The result of meiosis is cells with half the number of chromosomes as a somatic (non-sex) cell. This ensures that when the gametes join during sexual reproduction, the resulting organism has the correct number of chromosomes (half from each gamete). Thus meiosis maintains the chromosome number.

Females only contain X in their sex chromosomes. That s why females have XX and males XY. When females form gametes, they only can form them with a X chromosome. This however have some exceptions, for example, chicken females are XY whereas males are the one with XX.
