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

How is the standard deviation related to the variance?

True or False: If the heritability of arm span is 0.68 in humans, then 68% of the length of a person’s arms is controlled by his/her genes. The remaining 32% is controlled by the environment.

What are the works of Frederick Sanger made an impact in research and industry?

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?

A study of quantitative variation for abdominal bristle number in Drosophila fruit flies yielded estimates of VT =6.08, VG= 3.17 and VE= 2.91. What is the broad sense heritability?

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

What are the different types of biomolecules involved in cellular signaling, and how do they function?
