1- If the genotypic variance is 0.3 and the environmental variance is 3.3, how much is the heritability of broad meaning?

2-Three alleles are found for the gene encoding the alcoholic dehydrogenase. We found the following number of individuals for each genotype;

A^1 A^1= 45

A^1A^2=12

A^1a^3=20

A^2A^2=50

A^2A^3=30

A^3A^3=40

Calculate the frequency of each allele

1. Consider two genes that are independent, the A gene and the B gene. Each gene has two alleles (A gene: A1 and A2, B gene: B1 and B2). The frequency of A1 allele at the A gene is 0.37 and the frequency of the B2 allele at the B gene is 0.73.

1. Wool color in sheep is under the control of an autosomal gene which segregates two alleles: B,confers white wool, while the recessive allele b specifies black wool. A population of sheep under Hardy-Weinberg equilibrium was observed: Of 325 individuals, 194 have white wool and 131 have black wool. . What is the frequency of the B allele? b. How many of the 194 white sheep are expected to be heterozygous? 2. Cat coat color is controlled by an X-linked...

In this question, you have a set of ten quantitative values for each of three genotypes: aa, Aa, and AA (Table 1 below). Here, A is the risk or increaser allele. We use the genotype codes 0, 1, and 2, corresponding to the number of A alleles in an individual's genotype. GENOTYPE_CODE GENOTYPE 0 aa 1 Aa 2 AA Using each genotype code's ten quantitative values, you can compute the means and standard deviations. Given this information, what is the...
