It has long been known in the field of human genetics that wavy hair is the expression of a heterozygous genotype in which the allele for straight hair is paired with the allele for curly hair. Camille married Devin, and they both have wavy hair.What is the probability that their first child will have: a. wavy hair? b. curly hair? c. straight hair?

What is the name of the genetic phenomenon described in question above?

Solutions

Expert Solution

Punnet square: To detemine the probable genotype for the offspring using the parental genotype we can use the Punnet Square Test.

From the above punnet square experiment we can conclude that the probability of their first child for having-

a. Wavy hair is - 50%

b. Curly hair is- 25%

c. Straight hair is - 25%

This type of phenomenon is called the Co-dominance,where two types of different allel are fully express and produces another different phentype which is a mixture of the both the previous phenotype.

Hair type is an example of incomplete dominance (HCHC = Curly, HCHS = Wavy, HSHS = Straight).  A population contains 80 curly, 5 wavy, and 15 straight individuals.  Perform a chi-square analysis to determine whether or not this population is in Hardy-Weinberg equilibrium. a) Calculate your expected values b) Perform a chi-square analysis

In guinea pigs, white coat (w) is recessive to black coat (W) and wavy hair (v) is recessive to straight hair (V). A breeder crosses a guinea pig that is homozygous for white coat and wavy hair with a guinea pig that is black with straight hair. The F1 are then crossed with guinea pigs having white coats and wavy hair in a series of testcrosses. The following progeny are produced from these testcrosses: black, straight 30 black, wavy 10...

Matrix hair is a hair salon situated in a well-known shopping mall in Cape Town. The hair salon has a contract with a cleaning company that cleans the salon on a daily basis. The cost-structure of the total cleaning cost for a specific month consists of a fixed monthly fee and an additional cost per hour worked by cleaning staff. The fixed monthly fee charged by the cleaning company is constant between zero and 70 hours per month, but increases...

) In muskrats, short hair is recessive to long hair and brown coat is recessive to black coat. (Both are autosomal.) You cross a true-breeding short-haired black muskrat to a true-breeding long-haired brown muskrat. Let L= long and l= short, and let B= black and b= brown . A) Diagram this cross, showing the genotypes of the parents and the F1. B) Now you test cross the F1. Diagram this test cross, showing the genotypes of the F2 produced. C)...

18. Short hair in rabbits is governed by a dominant gene (L) and long hair by a recessive allele (l). Black hair results form the action of the dominant genotype (B_) and brown from the recessive genotype (bb). In a cross between homozygous short, black haired rabbit and a homozygous long, brown haired rabbit what are the phenotypic and genotypic ratios of the F1 and F2 generation.
