Gray tree frog (Hyla versicolor) males call to females, and their calls can be characterized by the pulse number and call period. The additive genetic variance of pulse number is 0.37, the additive genetic variance of call period is 0.16, and the covariance of the two traits is 0.25. What is the additive genetic correlation of the two traits?

Population A consists of 100 hens that are fully isogenicand that are reared in a uniform environment. Theaverage weight of the eggs they lay is 52 g, and the variance is 3.5 g2. Population B consists of 100 geneticallyvariable hens that produce eggs with a mean weight of52 g and a variance of 21.0 g2. Population B is raised in anenvironment that is equivalent to that of Population A.What is the environmental variance (Ve) for egg weight?What is the genetic variance in Population B? What is thebroad-sense heritability in Population B?

The narrow-sense heritability for a trait is 0.4 and the selection differential is 0.5. What isthe predicted response to selection?

A total of 310 green and golden bell frogs were studied on Broughton Island. It was noted that they seem to be bolder than those on the mainland. The genetic and environmental (residual) variances for this trait were as follows VE = 50; VG = 40; VI + D = 10. What is the narrow sense heritability for running speed? a. 0.80 O b. 0.66 c. 0.14 d. 0.33 e. 0.25

Monozygotic twin studies have allowed the correlation coefficient to be derived for a number of medical conditions. One example is blood pressure, where the coefficient is 0.6. Calculate the maximum value for the narrow sense heritability for blood pressure. B. 0.30 С. 0.50 D. 0.60 Е. 1.00

The two question below are confusing

In a population of cats, 12 cm^2 is the additive genetic variance for lenght of tail and 16 cm^2 is the total phenotypic variance. Based on these answer the followinng ques: Find the narrow sense heritability for this length of tail in the population of cats. What would be the covariance of two cats who are related to one another as being first cousins?

Tail length in a population of peacocks has a phenotypic variance of 2.56cm^2 and an enviromental variance of 1.14cm^2. What is the broad sense heritability (H2)?
