Question

[mark all correct answers]
a. Independent assortment of homologous pairs
b. The crossover events of Prophase I
c. Condensation of chromatin into chromosomes
d. Random fertilization of gametes
Oe. S-phase of interphase

Answer 1

The processes that result in genetic variation in sexually reproducing organisms include independent assortment, crossover events, and random fertilization.

Step-by-step explanation:

The correct answers that result in genetic variation in sexually reproducing organisms are:

1. Independent assortment of homologous pairs
2. The crossover events of Prophase I
3. Random fertilization of gametes

Independent assortment of homologous pairs occurs during metaphase I of meiosis, where homologous chromosomes line up randomly at the equator of the cell, leading to different possible combinations of chromosomes in the resulting gametes. The crossover events of Prophase I exchange genetic material between homologous chromosomes, creating genetic diversity. Random fertilization of gametes further increases genetic variation as any two gametes can combine during fertilization, resulting in unique combinations of alleles in the offspring.
