Question

Intrachromosomal recombination (recombination between genes on the same chromosome) occurs where in mitosis and/or meiosis?

A)Anaphase I of meiosis
B)Prophase I of meiosis
C)Anaphase I and anaphase II of meiosis
D)Prophase II of meiosis
E)Prophase of mitosis

Answer 1

Intrachromosomal recombination occurs during prophase I of meiosis. This is when homologous chromosomes exchange segments of genetic material, resulting in increased genetic variation.

Step-by-step explanation:

Intrachromosomal recombination, or recombination between genes on the same chromosome, occurs during prophase I of meiosis. This is when homologous chromosomes line up in pairs, known as tetrads, and exchange segments of genetic material through a process called crossing over. This genetic recombination between chromosomes results in new allelic combinations and increases genetic variation in the offspring.
