Multiple Choice

Allele pairs are most likely to assort independently of one another when:

the genes are located on different chromosomes

the genes are located very close together on the same chromosome

crossing over does not occur during meiosis

the genes are always inherited together due to linkage

Verified step by step guidance

Understand the concept of independent assortment, which states that allele pairs for different genes segregate independently during gamete formation, leading to genetic variation.

Recall that independent assortment is most likely to occur when genes are located on different chromosomes because they segregate independently during meiosis I.

Recognize that genes located very close together on the same chromosome tend to be inherited together due to genetic linkage, reducing independent assortment.

Note that crossing over during meiosis can break linkage by exchanging segments between homologous chromosomes, increasing the chance of independent assortment for linked genes.

Conclude that the strongest condition for independent assortment is when genes are on different chromosomes, as this ensures their alleles assort independently without being affected by linkage or crossing over.
