In order to determine the narrow sense heritability of a trait, h2, a scatterplot is made plotting midoffspring values of the trait against midparent values of the same trait. The narrow-sense heritability is then defined as: Group of answer choices the difference between the highest and the lowest trait values, squared the mean of the slopes of both the best fit and the worst fit lines through the data points the sum of all the parental values minus the sum...

1. Low platelet count is a recessively inherited trait. Reevaluation of the genetic screen indicates that Nikoleta is homozygous dominant normal for a trait that causes low platelet count and her husband is homozygous recessive. If the F1 offspring has normal platelets and beta-thalassemia (15pts). a. What are the parental gametes? (2pts) b. Based on the F1 progeny phenotype given and the parental gametes, write the two possible genotypes. (2 pts) c. What is the gamete frequency if the two...
