1. Fixation of Dominant Alleles Start with a population that has a gene with two alleles (A and a) with classical Mendelian dominance that are at equal frequency (p0.5. q 0.5). Assume this first generation is at hardy Weinberg equilibrium. Calculate the genotype frequencies AA- a. Aa b. Now assume some environmental change that makes the recessive phenotype completely unfit (fitness- 0). Calculate the allele frequencies and genotype frequencies in the second generation. (Hint: Your calculations might be easier if...

Consider a locus of interest that has two alleles: A and a. A diploid individual carrying these alleles can have one of three genotypes: AA, Aa, or aa; a population will consist of some combination of AA, Aa, and aa individuals. The relatively frequency of each of these genotypes makes up the population's structure. Hardy and Weinberg independently figured out that, in the absence of forces that cause evolutionary change, the population structure will 'settle' or default to equilibrium values,...

1.)If the population frequencies of two alleles at a locus are B = 0.5 and b = 0.5, what is onepossible set of frequencies for the three resulting genotypes that would NOT reflect Hardy- Weinberg equilibrium? 2.)In a population that is in Hardy-Weinberg equilibrium, the frequency of the homozygous recessive genotype is 0.09. What is the frequency of individuals that are homozygous for the dominant allele? 3.)In humans, Rh-positive individuals have the Rh antigen on their red blood cells, while...

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...

If there are are 9 individuals in population "X", and with regards to gene "A", 4 individuals are AA, 3 are Aa and 2 are aa, what is the frequency of the recessive allele? .456 .388 .611 The numerical value cannot be determined given that this population is too small and is not in Hardy-Weinberg equilibrium. Willie Nelson and Metallica invented population genetics!! I know is B but I do not know how to get there. Please explain steps

In a population of Mendel's garden peas, the frequency of the dominant A (purple flower) allele is 80%. Letp represent the frequency of the A allele and q represent the frequency of the a allele. Assuming that the population is in Hardy-Weinberg equilibrium, what are the genotype frequencies? A. 16% AA, 40 % Aa, 44 % aa B. 80% AA, 10 % Aa, 10 % aa C. 50 % AA , 25 % As , 25 % aa * E....

MN blood type in humans is determined by two alleles at a single
co-dominant locus; these alleles are LM and
LN. In a sample of 1190 individuals , it was found
that:
75 had type M blood (LMLM)
800 had type MN blood (LMLN)
315 had type N blood (LNLN)
Given this population data, calculate the observed
allele frequencies and the expected number of individuals
of each genotype. For allele frequency reposes, please round to 3
decimal places (ex. 0.000)....
Suppose that individuals in a population of annual plants have leaves that are divided into leaflets,...
Suppose that individuals in a population of annual plants have leaves that are divided into leaflets, toothed along the edges, or smooth along the edges. The degree to which the leaves are divided is determined by a single gene with two alleles. The genotype DD results in leaves with smooth edges, the genotype Dd results in leaves with toothed edges, and the genotype dd results in divided leaves. Calculate the genotype frequencies of a population that contains 128 individuals with...

1. Suppose a population of organisms is in Hardy–Weinberg equilibrium. In the population, a gene has two alleles, B and b. If the frequency of B is 0.72 and the frequency of b is 0.28, what are the expected genotype frequencies of BB, Bb, and bb? Calculate each frequency to two decimal places.
