What is the chi-square value of the pumpkin population? round up and use four decimal points After doing some crosses and genotyping some individuals, you determined that the number of individuals homozygous dominant for the largest pumpkin allele is 98, 80 are heterozygous for medium size, and 20 are homozygous recessive for small size.

If both parents are mixed hybrids, what is the phenotype in percentage (%) for the possible offspring? Use the reference sheet below to answer.

I need help calculating observed allelic frequencies. I'm in a biology lab and we did a classroom experiment where we were each given genotypes and simulated multiple generations by coinflip. This is the end data after multiple generations and we need to extrapolate p & q: AA individuals - 2 Aa individuals - 13 aa individuals - 5 My understanding is that the genotypic frequencies would simply be their %. So AA would be 0.1, Aa would be 0.65, and aa would be 0.25. This should mean that AA = 0.1 = p^2 and aa = 0.25 = q^2. Which should also mean that taking the square root of these numbers would give me p and q.... but they don't add up to 1. Squaring them gives me a p value of ~0.32 and a q value of 0.5. How is this possible? Shouldn't this method work to give me p and q since I know the exact genotypic frequencies? If anyone can clear up why this doesn't work, I would be extremely appreciative. Thank you!

If you cross a mouse with Ff genotype with another mouse with Ff genotype, what is theprobability of exactly 2 out of 6 of their offspring also having Ff genotype? Show your work using binomial and (p+q)^n

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?

When Mendel performed mono-hybrid crosses with opposing traits (i.e. purple flowers and white flowers) what did he see in the in F2 generation?     He found that the trait that had dissappeared in the F1 generation returned in 25% of the F2 generation     He found that both traits continued to be present in 50% of the F2 generation, just like the F1 generation     He found that the trait that had dissappeared in the F1 generation returned in 50% of the F2 generation     He found that the trait that had dissappeared in the F1 generation returned in 75% of the F2 generation

If both parents are mixed hybrids, what is the phenotype ratio for the possible offspring?Use the reference sheet below to answer.

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”)
