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.

Cis Trans

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

Green-Blue-Red Green-Red-Blue Red-Green-Blue

Answer #1

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.

In an ornamental plant, silver-colored flowers (s) are recessive to blue-colored flowers (S), red leaves (r) are recessive to green leaves (R), and long stems (l) are recessive to short stems (L). All three genes involved are located on the same chromosome. Two true-breeding strains were crossed to produce an F1 plant. Then, this F1 plant was test-crossed to a plant with silver flowers, red leaves, and long stems, to produce the following progeny: progeny phenotype count of progeny silver...

6. Red-green color blindness occurs in about 8% of males and .4% of females. Many genes contribute to Red-green colorblindness and most of these are sex-linked, which is the reason for the disparity in the frequency between males and females. Call the allele that encodes a functional product "+" and the allele that encodes a non-functional product "=". Why is Red-green color blindness more fequent in males? a.   because males inherit only a single X chromosome, which means that inheriting...

Simple Dominance with 2 genes A gene in cats causes them to be black (dominant) or brown (recessive). A second gene causes cats to be agouti (have stripes on their hairs) or non-agouti (solid colored hairs). If you did a dihybrid cross between two black haired agouti cats, what fraction of the offspring would be expected to have each phenotype? If a dihybrid black agouti cat mated with a brown cat that was heterozygous for the agouti gene, what fraction...
