A correlation coeffiicient of zero means two variables do not vary in a consistent way with each other.   True or false?

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?

In your own words, explain the meaning of the term heritability.Why is a heritability value valid only for a particular population ofindividuals raised in a particular environment?

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

Why is the probability of flipping a coin twice different than flipping two coin at the same time?

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?

One variety of pigs reach maturity at 81 days with a variance of 6.4 days2 while a second variety takes 93 days to reach maturity with a variance of 6.6 days. An F2 population derived from these populations takes 87 days to reach maturity and has a variance of 8.5 days. What is the broad-sense heritability for this trait?

None

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)?
