1. IIn garden pea plants, the yellow seed colour (Y) is dominant over the green seed colour (y).

In a population of 40 pea plants, 15 pea plants are homozygous dominant, 15 are heterozygous dominant, and 10 are recessive.

Find the frequency of the

a.    YY genotype
b.    Yy genotype
c.    yy genotype

2.In sheep, a hairy coat (H) is dominant over woolly fleece (h).
In a population of 20 sheep, 9 sheep are homozygous dominant and 9 sheep are heterozygous dominant.

Find the frequency of the

a.    H allele
b.    h allele

Record your answer as a value between 0 and 1 rounded to two decimal places.

3. In fruit flies, long wings (L) are dominant over short wings (l).

In a population of 26 fruit flies, 0 have LL genotypes, 18 have Ll genotypes, and 8 have ll genotypes.

Find the frequency of

a.    long-winged fruit flies   
b.    short-winged fruit flies

Record your answer as a value between 0 and 1 rounded to two decimal places.

In peas, yellow seed pod (Y) is dominant to green seed pod (y), and inflated seed pod (N) is dominant to constricted seed pod (n). These two loci are NOT linked. A true-breeding pea plant with yellow, inflated pods is crossed to a true-breeding plant with green, constricted pods. The F1 progeny are self-fertilized. What is the probability of obtaining a plant that produces yellow, constricted seed pods in the F2?

Question 1 Yellow seed color is dominant to green seed color. A green seeded plant is crossed with a heterozygous plant. What phenotypic and genotypic ratios would you predict in the offspring? If I planted 200 of these offspring, how many would be green? How many would be yellow? Explain how you solved the problem.

In garden pea plants, tall stem length (T) is dominant over short stem length (t). In an ideal garden pea plant population exhibiting Hardy–Weinberg equilibrium, if allele T has a frequency of 0.88, what percentage of the population is recessive for this trait? Round your answer to the nearest whole number. -------- There is a lack of dominance in black (B) and white (W) horse coat colours. An offspring produced from a black horse and a white horse has a...

The recessive traits in garden pea plants are as follows: yellow pods (g) are recessive to green pods (G); bluish-green seedlings (s) are recessive to green seedlings (S); creeper (p) (a plant that cannot stand up) is recessive to normal (P). A homozygous plant with green pods, green seedlings and normal stature was crossed to a creeper with yellow pods and bluish-green seedlings. The F1 plants were then crossed to creepers with yellow pods and bluish-green seedlings. The following results...

In garden peas, tall plants are dominant to short plants and smooth seeds are dominant over wrinkled seeds. If two heterozygous tall plants with smooth seeds (TtRr) are crossed, what are the potential genotypes and phenotypes that can be expected in the offspring? What is the genotype of the parents? What are the gametes for each parent? What is the phenotypic ratio? What proportion of the Tall plants with smooth seeds is heterozygous for both traits?
