Multiple Choice

For two genes on the same chromosome, a recombinant gamete will be produced only if a(n):

crossing over event occurs between the two genes during meiosis

mutation occurs in one of the genes

gene conversion event happens at a distant locus

chromosome is duplicated before meiosis

Verified step by step guidance

Understand that genes located on the same chromosome are said to be linked, meaning they tend to be inherited together unless a recombination event occurs.

Recall that recombinant gametes are those that contain a new combination of alleles different from the parental types, which can only happen if the physical arrangement of alleles changes.

Recognize that crossing over is the process during meiosis where homologous chromosomes exchange segments, potentially between two genes on the same chromosome, creating new allele combinations.

Note that mutation, gene conversion at a distant locus, or chromosome duplication do not directly cause the formation of recombinant gametes between two linked genes.

Conclude that the production of recombinant gametes for two genes on the same chromosome requires a crossing over event between those two genes during meiosis.
