1. Which process makes variation / genetic diversity possible?
a. Mitosis
b. Meiosis
c. Both
d. None
1. Even though humans are approximately 99.9% identical in their genetic makeup, an incredible amount of variation is seen among individuals of the species. This genetic variation is greatly influenced by the process of meiosis.
Of the following events that occur during meiosis, which contributes most to genetic diversity in the human population?
A. Condensation of chromatin during meiosis I
B. Recombination between homologous chromatids during meiosis I
C. Alignment of sister chromatids at the metaphase plate during meiosis II
D. Separation of sister chromatids during meiosis II
Homologous chromosomes contain genes that code for the same traits, but they carry different versions (alleles) of these genes.
True
false
