Gray tree frog (Hyla versicolor) males call to females, and their calls can be characterized bythe 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 is0.25. What is the additive genetic correlation of the two traits?
You have just started working in a field research laboratory focused on a species of Redtailed Hawks. They have been trying to understand the heritability of wingspan in this species. They’ve studied them in 2 different contexts. In the wild, and in an indoor enclosure that is temperature controlled and provides them with a standardized diet, eliminating environmental variance. In the wild, the total variance was determined to be 24 inches. In the enclosure, total variance between subjects was found to be 8 inches.In the enclosure, what is the VEnvironmental They ask you to figure out what the VEnvironmental (environmental variance) is for the hawks in the wild. (Hint: First identify Vgenetic in the enclosure. What is the heritability of wingspan in the wild?

You are a rabbit breeder, and you decide that you want rabbits with long fur. Thephenotypic variance of fur length is 4 cm2. The covariance of fur length between betweenfull sibs is 1 cm2. The mean fur length in the initial population is 3 cm. You choose to breedthe top 1/3 of the population with the longest fur, and their mean fur length is 5 cm. Assumethat the covariance between sibs is due to only additive genetic variance.a) What is the narrow sense heritability (h^2 ) of fur length?b) What do you expect the mean fur length to be in the progeny of rabbits you breed?c) How many generations of this selection regime will it take for the mean fur length of thepopulation to be 10 cm? (Assume heritability and additive genetic variance remainunchanged throughout this process.)
What role would twin and adoption studies play in selecting a model for determining whether attendance at medical school is a heritable trait? What heritability values would make you take the study to the next level?
The leaf width of a particular plant has an environmental variance of 2.3 cm, an epistatic variance of4.8 cm, a dominance variance of 1.6 cm, and an additive variance of 3.8 cm. Determine, and interpret,the broad sense and narrow sense heritability.
Two inbred lines of rice are intercrossed. In the F1, the variance in panicle weight is measured to be 12 g2. The F1 is selfed, and in the F2, the variance in panicle weight is 38 g2. Estimate the broad sense heritability of panicle weight in the F2 population of this experiment. If there is no genetic variation within a population for a given trait, what is the broad sense heritability value for the trait in the population?

A graduate student is studying a population of bluebonnets along aroadside. The plants in this population are genetically variable. Shecounts the seeds produced by each of 100 plants and measures the meanand variance of seed number. The variance is 20. Selecting one plant,the student takes cuttings from it and cultivates them in a greenhouse,eventually producing many genetically identical clones of the sameplant. She then transplants these clones into the roadside population,allows them to grow for one year, and then counts the seeds produced byeach of the cloned plants. The student finds that the variance in seednumber among these cloned plants is 5. From the phenotypic variancesof the genetically variable and the genetically identical plants, shecalculates the broad-sense heritability.
