Independent orientation of chromosomes at metaphase I results in an increase in the number of
A) gametes.
B) homologous chromosomes.
C) possible combinations of characteristics.
D) sex chromosomes.

Question

Quizplus · Accepted Answer

Independent orientation of chromosomes at metaphase I during meiosis leads to the formation of numerous possible combinations of characteristics or traits. This is because each pair of homologous chromosomes aligns randomly at the metaphase plate, and the orientation of one pair does not affect the orientation of another pair. As a result, the random assortment of chromosomes during meiosis I generates a high level of genetic variability in the resulting gametes, which increases the number of possible combinations of inherited traits in the offspring. Thus, the correct answer is C.
