Calculate the frequencies of the AA, Aa and aa genotypes after one generation if the initial population consists of 0.2 AA, 0.6 Aa and 0.2 aa genotypes and meets the requirements of the Hardy-Weinberg relationship. What genotype frequencies will occur after a second generation?

Using the observed counts for each genotype, how do you find the expected values with those numbers and the frequencies?

A population of 40 asters segregating at two loci with two alleles each (A/T and G/C) has 8 individuals with the AAGGgenotype. The allele frequencies of A and G are 0.5 and 0.5 in the population.   What is the coefficient of gametic disequilibrium, D?   What is the value of Lewontin’s D’? (that is “D prime”)

Consider the following three point trihybrid testcross ibvolving traits in dragons. The genotypes determining the 8 progeny types from this testxross are shown below out of a sample of 1572 flies. What number of progeny for each genotype would you predict in the case of independent assortment. gametes number K L M  621 klm    608  k L M  103 K lm    109  K lm    64 k L m    57 K L m    3 k l M   7

The question should be whether you reject or do not reject the Fisher test null hypothesis using data for all three institutions, not for two.  Test that Mode ofInheritance is Autosomal Recessive forexperiments at each of three researchinstitutions At two research instructions, the parental cross is a affected(disease) male with an unaffected (wild‐type) female. Thecross of a male and female in the F 1generation produces thefollowing counts in the F 2generation:  Question to be answered:  Computethe Fisher Combined P‐value test using the data fromthe two sites, and draw a conclusion (reject, do notreject) the null hypothesis for the Fisher test, namelythat the specified MOI at each site is correct. https://onlinelibrary.wiley.com/doi/10.1002/aff2.68(only abstract) https://bigislandnow.com/2022/10/23/native-predatory-fish-help-control-invasive-species-in-hawaiian-fishpond-on-o%CA%BBahu/#:~:text=Jacks%20and%20barracuda%20in%20He%CA%BBeia,on%20the%20invasive%20mullet%20species.

With a genotype of the parents of YYRR x YyRr, what is the percent probability of offspring having a genotype of Yyrr? 75% 50% 25% 0%

What would the genotypes and genotypic ratio be for the F2 generation produced in a phenotype and phenotypic ration of F1 individuals that were produced from a male blue tailed gecko crossed with a female green tailed gecko, being that all 28 of the offspring had green tails, were mated brother and sister?
