Question

1) Meiosis causes genetic variety by two processes of genetic _______.

A) nondisjunction

B) polyploidy

C) recombination

D) mutation

E) anueploidy

2) Initial development of the zygote to become the 2-cell stage, 4-cell stage, and 8-cell stage is dependent upon ______.

A) mitosis

B) differentiation

C) fragmentation

D) meiosis

Answer 1

Answer 1: Meiosis causes genetic variety by two processes of genetic Recombination.

The recombination occurs at the crossing over stage of meiosis. there the crossovers lead to recombination of genes leading to genetic variety and diversity.

Answer2:

Initial development of the zygote to become the 2-cell stage, 4-cell stage, and 8-cell stage is dependent upon _____mitosis_.

simple equational division takes place till the gastrulation stage, where the number of cells is doubled with every division.
