What does crossing over during meiosis result in?
A
Increased genetic variation in gametes
B
Formation of identical daughter cells
C
Reduction in chromosome number
D
Synthesis of new DNA strands
Verified step by step guidance1
Understand that meiosis is a type of cell division that reduces the chromosome number by half, resulting in the production of gametes (sperm and eggs).
Recognize that crossing over is a process that occurs during prophase I of meiosis, where homologous chromosomes pair up and exchange segments of genetic material.
Realize that this exchange of genetic material between homologous chromosomes leads to new combinations of alleles, which increases genetic variation among the resulting gametes.
Consider that increased genetic variation is crucial for evolution and adaptation, as it provides a population with a wider range of traits that may be beneficial in changing environments.
Conclude that the primary result of crossing over during meiosis is increased genetic variation in gametes, which is essential for the diversity of offspring.
