A dragon biologist is setting up an experimental population of 1000 individuals. In dragons, pointy crests are dominant to rounded crests. In the experimental population, the frequency of the pointy crest allele is 0.2.
a. Assuming Hardy-Weinberg is in effect, how many individuals will have the pointy crested phenotype? b. What is the frequency of round crested individuals in the population? c. What is the probability that the round crested allele gets fixed?

A population of flour beetles has 1000 individuals. Normally the beetles are red in color; however, this population has a utation in the gene for body color that results in black beetles that are designated by the rr genotype. Red body color is dominant to black so the genotypes RR and Rr result in red beetles. Assume the population is in Hardy-Weinberg equilibrium, with a 50% frequency of each allele for body color. A) --- what is the frequency of...
An Amazon rainforest population of leaf beetles has 100,000 individuals.
An Amazon rainforest population of leaf beetles has 100,000 individuals. The beetles exist in two color morphs, purple and green. Purple beetles live on epiphytic orchid blooms whereas the green beetles inhabit the leaves of the orchid plants. The color is controlled by two alleles at a single gene locus. The purple allele (P) is dominant to the green allele (p) 36% of the beetle population is green and the other 64% of the population is purple. Assuming the population...

1. You are studying a population of sandblossoms (Linanthus parryae) that has individuals with blue and white flowers. The allele for white flowers (A) is dominant to the allele for blue flowers (a). In the population you survey, 91 out of 100 individuals have white flowers. Based on this information: a. Calculate the frequency of the A and a alleles. b. Calculate the numbers of each genotype. 2. A population of snapdragons (Antirrhinum hispanicum) has two additive alleles for flower...

Cystic fibrosis is an autosomal recessive disorder. In one population, the frequency of affected individuals (A 2 A 2) is 0.0004 Assuming that this population is under Hardy- Weinberg equilibrium, calculate all allele frequencies and genotype frequencies. Enter your numerical answers in the boxes below. Express each answer to four decimal places.

The occurrence of the NN blood group genotype in the US population is 1 in 400, consider NN as the homozygous recessive genotype in this population. You sample 1,000 individuals from a large population for the MN blood group, which can easily be measured since co-dominance is involved (i.e., you can detect the heterozygotes). They are typed accordingly: BLOOD TYPE GENOTYPE NUMBER OF INDIVIDUALS RESULTING FREQUENCY M MM 490 0.49 MN MN 420 0.42 N NN 90 0.09 Using the...

5. Fur colour in mice is a single gene trait controled by two alleles. In a population of 75 mice, 21 are homozygous dominant, 37 are heterozygous dominant, and 17 are homozygous recessive. What is the frequency of the dominant allele in the population? Show all work and record your answer as a value between O and 1 rounded to two decimal places 6. The Hardy-Weinberg principle states that allele and genotype frequencies remain constant from one generation to the...

Let's review how p and q are calculated.
Count up all the red balls, then count
all the white balls. What percentage of all the alleles are red?
Since 16 of the 20 balls are red, 16/20 = 80%. Expressed as a
decimal, we could say the frequency of the CR allele is 0.8.We will
follow the convention of using p for the frequency of one allele
(the dominant allele, if the trait is dominant/recessive), with q
being the frequency...
