Question

Red, Blue and Green are three genes found on the same chromosome. Each gene has two alleles: R or r, B and b, and G and g, respectively. The somatic cells and gametes of a person that is heterozygous for the alleles of all three genes are studied to understand the relationships between the three genes. It is found that the dominant alleles for Red and Green is on the person’s paternal chromosome, but the dominant allele for Blue is on the person's maternal chromosome. By genotyping 100 gametes from this person, it is found that recombination occurred between Green and Blue in 16 gametes, between Red and Green in 10 gametes, and between Red and Blue in 4 gametes.

The alleles for the three genes are said to be in the ___________ configuration.

What is the relative order of Red, Blue, and Green genes on the chromosome?

Explanation / Answer

Green-Red-Blue

Explanation:

-One primary gets individuals that are heterozygous for together genes.

-This might be attained by crossing a separate homozygous leading for mutually genes to one homozygous receding for both genes, resultant in a heterozygote by genes in coupling configuration.

-Otherwise, a discrete that is homozygous receding for one gene may be traversed to a separate that is homozygous receding for the additional gene, resultant in a heterozygote with genetic factor in revulsion.
