Genetics - Worksheet #5
Incomplete Dominance / Codominance
Name _____________________________ Date___________ Class___
Show the cross and then answer the question for each problem. (For your
answer use a different color, please)
1. In shorthorn cattle the gene for red coat color is not dominant over that for white coat color.
The heterozygous condition produces a roan color. A breeder has a white, red, and roan cows and bulls. What ​phenotypes​ can be expected from the following crosses?
A. Red x roan RR x Rr B. Red x red
C.. Roan x white D. Red x white
2. A homozygous black chicken is crossed with a homozygous ​splashed white​ chicken ( white with black splashes same as the chicken in the video) and the resulting offspring are ​blue Andalusian chickens​. Cross two heterozygous Andalusian chickens and give the results of their offspring.
3. In snapdragons, flower color shows incomplete dominance. Homozygous plants are white, and heterozygous plants are pink. What type of flowers will result in the F​ ( first
generation)of red and white? In the F2 ‘s (end generation)?
red or
frizzle
4. In Poultry, a form of incomplete dominance is for the trait” frizzle” F = frizzle N = no
and FN = slightly frizzled. If a frizzled male is crossed with a non-frizzled female, what will be
the genotypes and phenotypes for the F​ generation? 1​
IntheF​ ‘s

Homework Answers

Answer #1

It is given that Red id not dominant over white.

So the genotype of red is RR

The genotype of roan is the Rr

The genotype of white is rr.

so Red and Roan cross will be

R R
R RR = Red RR = Red
r Rr = Roan Rr = Roan

Red and Red cross will be

R R
R RR = Red RR = Red
R RR = Red RR = Red

Roan x white cross will be

R r
r Rr = Roan rr = White
r Rr = Roan rr = White

Red x white

R R
r Rr = Roan Rr = Roan
r Rr = Roan Rr = Roan

In cattle, roan color (mixed red and white hairs) occurs in the heterozygous (Rr) offspring of red (RR) and white (rr) homozygotes. When two roan cattle are crossed, the phenotypes of the progeny are found to be in the ratio of one red: two roan: one white. Which of the following crosses could produce the highest percentage of roan cattle? a) red x white; b) roan x roan; c) white x roan; d) red x roan e) all of the...

Tallness (T ) in snapdragons is dominant to dwarfism (t ), while red (R ) flower color is incompletely dominant to white (R' ). The heterozygous condition results in pink (RR' ) flower color. The genes for these traits occur on separate chromosomes. A dwarf, red snapdragon is crossed with a plant homozygous for tallness and white fowers. a) Determine the genotypes of the parents. b) Determine all the types of gametes each parent can produce. c) Complete the Punnett...

Please show WORK! In some horses, coat color is autosomal and exhibits incomplete dominance, with palamino coloration intermediate to both chestnut and cremello coloration. Horses can also exhibit an immunodeficiency syndrome inherited as an X-linked recessive allele. You are a horse breeder, and cross a palamino female carrier for immunodeficiency syndrome with a normal, cremello male. 1. Use appropriate genetic notation to describe genotypes of the cross. 2. If you conducted this cross many times, what would be the expected...

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...
