Chapter 16.1, Problem 4CC
Summary Introduction
To determine: The ratio of “T” to “t”allele in the F2 progeny and identify if the ratio is similar to the
Introduction: An allele is defined as a variant of a gene responsible for coding a specific character. There are atleast two different alleles for each phenotypic characteristics. One allele is dominant while the other form of the allele is recessive. The interaction between the alleles is responsible for different phenotypic traits. These interactions can produce three types of genotypes: homozygous dominant, heterozygous and homozygous recessive.

1. Predict the phenotypic ratios of offspring when a homozygous white
cow is crossed with a roan bull. Illustrate using a Punnett square.
2. Complete the Punnett square for a cross between a black chicken (BB) and a
white chicken (WW). Give the phenotype of the offspring in the F1 generation.

Co-Dominance: In co-dominance, the heterozygous individual exhibits the phenotype for
both alleles. We used the ABO blood groups as an example of co-dominance.

First, you list all possible gametes each parent and subsequent parents can produce. Second, you then assign the gametes to a Punnett square and fill it in. Finally, you count the progeny and determine the number of progeny in each phenotypic category. Remember, when determining the types of gametes possible, each gamete must have one member of each homologous pair of chromosomes. This means there needs to be one copy of every gene. For example, if you are considering a T gene (ability to taste PTC) and an F gene (let's say earwax texture- wet earwax is dominant and dry earwax is recessive), each gamete must have one allele for the T gene (either T or t) and one allele for the F gene (either For f).arrow_forward

This is easily recognized when the phenotype is somewhere between two extremes. Counting the parents, there are three phenotypes (black, white, grey) being expressed in these flowers instead of only two, and that third phenotype is intermediate between the other two. This heterozygous condition is called incomplete dominance. 1.
