Question

A. Starting with a diploid cell that has 8 chromosomes, draw out/compare and contrast mitosis with meiosis. Label and describe what happens during each stage as well as the maternal and paternal chromosomes. Also label the reductional and equational division for both processes when appropriate.

B. Using 2 of the chromosomes you created above (one maternal one paternal), discuss how sexual reproduction creates genetic variation for evolution act upon during meiosis. How does this compare to asexual reproduction for eukaryotes in the long run, as well as binary fission

Answer 1

(A)  Mitosis cell division: When the diploid cell (2n) divided into two diploid daughter cell (2n) and contains the same character as the parent cell is called the Mitosis division.

Meiosis cell division: When the diploid cell (2n) is divided into four haploid cells is called the Meiosis division.

(B) In case of sexual reproduction the produced gamets are haploid (n) type and the games of the both parents meets and produce zygote (2n),so when teo types of gametes or games from two parents meets the two different type of genetic characters meet in the zygote sowe can observe genetic variation for evolution which are the mixture of the both parents.

But in case of the asexual reproduction of the eukaryotes (binary fission)the mitosis division take place so the produced daughter cell contains the same type of gene and genetic character of the parents so it is helpful in some cases as they could esaily survive in the enviournment as the genetic type is same as the parent cell.
