Recognize The Steps Of Meiosis,recall Major Events Of The Steps, Recall The Significance Of Meiosis In Reproduction, Compare Mitosis And Meiosis.

What is the name of the process that results in daughter cells with 1/2 the number of chromosomes as the parent cell?
a) meiosis
b) mitosis
c) cytokinesis
d) interphase

If gametes were produced by mitosis, the zygote formed from their union would
a) have twice the number of chromosomes as the parent's body cells.
b) have 1/2 the number of chromosomes as the parent's body cells.
c) have the same the number of chromosomes as the parent's body cells.
d) have 4 times the number of chromosomes as the parent's body cells.

If the haploid number of chromosomes for a buffalo is 30, the number of chromosomes in an egg will be
a) 30
b) 60
