A species of scarab beetles have red, orange or golden wing covers. A cross between a pair of orange beetles gave 3/4 orange and 1/4 golden offspring. A cross between a red and an orange pair have 1/2 red and 1/2 orange offspring. How do you explain these results? Choose the best answer. The trait is controlled ….

Select one:

by three alleles with dominance and recessive relations

by three alleles with incomplete dominance

by three alleles with both dominance, incomplete dominance and recessive alleles

by two alleles with incomplete dominance

by two alleles with dominance and recessive relations

Answer #1

Answer is

by three alleles with dominance and recessive relations.

Explanation

From both cross it can be concluded that trait is control by three alleles in dominant and recessive relationship

For each gene, assume the capital letter indicates a dominant allele and the lower case letter (small) indicates a recessive allele.

Suppose you have a group of beetles. You find that a white eye color in one of the beetles is due to a point mutation. Refer to B and b (where B is the allele associated with the dominant phenotype, and b is the allele associated with the recessive phenotype) in order to answer the following questions: 1) The cross of a pure breeding male with white eyes with a pure breeding female with normal eyes leads to all offspring...

We have a population of snakes. They are either all black or black with red stripes. We make the following crosses to help us determine the gene interaction: A cross between the solid black snakes and the striped snakes results in a 1:1 ratio of solid black to striped snakes among the offspring. A cross between two striped snakes results in progeny in the ratio of 2 striped for every 1 solid black. Assume that these outcomes are manifested by...

In a parrot species, feather colour is determined by incompletely dominant sex-linked alleles: Red (ZR) and white (ZW). A pink male is bred many times with a red female. They produce the following offspring: Red male: 79 Pink male: 65 Red female: 82 White female: 46 1 What is the expected phenotype ratio of red males : pink males : red females : white females? 2 How often would this cross result in male offspring that are white? 3 What...

In golden retrievers, the D/d gene codes for an enzyme that produces a pigment. The dominant allele (D) results in a golden pigment, while the recessive allele (d) codes for red pigment. Additionally, the V/v gene produces a transport protein responsible for depositing the pigment produced by D/d into the hair. When the dominant V allele is present, the color expressed by D/d will be deposited and the dog will be that color (golden or red). However, allele v is...
