Solutions

Expert Solution

1. Option a is the right answer as the genome is defined as total genetic material present in a cell or organism or total genes present in the cells or organism.

2. Option d is the right answer as at the mitosis one somatic cells divided into two cells with equal size and genetic material.

3. Option a is the right answer because bone marrow is highly proliferative tissue which generates the blood cells by the process of mitosis.

4. Option d is the right answer because of testis or ovary are the place where gametes are formed by the process of meiosis.

5. Option c is the right answer as at the end of the meiosis daughter cells contained half of the mother cell chromosomes.
