Question

what is the reason that closely linked genes are typically inherited together?
alleles are paired together during meiosis.
the number of genes in a cell is greater than the number of chromosomes.
chromosomes are unbreakable.
the likelihood of a crossover event between these two genes is low.
check answer

Explanation:

Closely linked genes are located near each other on the same chromosome. During meiosis, the likelihood of a crossover event (which can separate genes) between closely - linked genes is low. Crossover events occur at random points along the chromosome, and the closer two genes are, the less likely there will be a crossover between them. Chromosomes are breakable (through processes like crossover itself or chromosomal breakage in mutations). The number of genes in a cell being greater than the number of chromosomes is a general genomic fact but not the reason for close - linkage inheritance. Alleles are paired during meiosis (as in homologous chromosomes having alleles of the same gene), but this is about allelic pairing in general, not the reason for close - linkage inheritance.

Answer:

The likelihood of a crossover event between these two genes is low.
