Question

which of the following causes genetic recombination? select all that apply.
a) independent assortment
b) crossing over
c) alleles
d) segregation

Explanation:

• Option A: Independent assortment (during meiosis) leads to different combinations of chromosomes in gametes, causing genetic recombination.
• Option B: Crossing over (exchange of genetic material between homologous chromosomes in meiosis) directly results in new combinations of alleles, a form of genetic recombination.
• Option C: Alleles are variants of genes, not a process that causes recombination.
• Option D: Segregation is the separation of alleles during gamete formation, not a cause of recombination.

Answer:

A) independent assortment, B) crossing over
