Among a particular population of 100 plants, red flowers are dominant and yellow flowers are recessive. F is the dominant allele and f is the recessive allele. 40 plants are homozygous dominant • 44 plants are heterozygous 16 plants are homozygous recessive Use the Hardy-Weinberg equation to calculate the equilibrium frequencies of each genotype
In corn, kernel color is governed by a dominant allele for white color (A) and by a recessive allele for yellow (a). A random sample of 152 kernels from a population that assumes Hardy- Weinberg principle reveals that 117 kernels are white. What is the frequency of individuals with the homozygous recessive genotype? O 0.27 O 0.56 O 0.23 O 0.26 O O o O
A different locus codes for drought tolerance in desert tortoises. On average during a drought, genotype AA produces 7 offspring, genotype AB produces 8 offspring, and genotype BB produces 3 offspring. The genotype frequencies in 2019 are 10% AA, 10% AB, and 80% BB. What is the expected equilibrium allele frequency p* after a large number of generations go by during the drought? Assume the tortoise population is also very large.
There are 100 Hodags in an isolated population. Ninety-six have eyes that glow red, whereas four have eyes that glow green. If the four green-eyed hodags (4%) represent the frequency of the homozygous recessive genotype, please calculate the following: 3a. the frequency of the recessive allele (round to the nearest tenth)
Please refer to the Chi squared step by step document for an example to follow. 4a. A large random sample taken from a natural population of flowering plants found 300 plants with red flowers (RR genotype), 150 with pink flowers (Rr genotype) and 38 white flowers (rr genotype). Is the population in HWE? Step 1 Calculate the frequencies of alleles R and r. Include the formula for calculating allele frequencies in a population. Ans: Step 2 Based on the allele frequencies how many individuals are expected to a certain genotype? Calculate by multiplying the number of individuals in population (n) x frequencies of alleles for that genotype: Ans: T Step 3 Fill in the Table Below Genotype Ans: RR Rr rr Observed Expected Obs - Exp Step 3 Use the following formula to calculate the Chi squared value., Note calculate for each genotype and get the sum.

In a population of 200 people, an allele F has a frequency of 84%. What is the frequency of allele f? Using the Hardy-Weinberg equation, estimate the numbers of homozygous dominant, heterozygous, and homozygous recessive genotypes. (Remember that the formula is: p2 + 2pq + q2 = 1, where p represents the dominant allele and q represents the recessive allele.) *Be sure to account for all 200 people in the population.

What are the allele frequencies of the W and w alleles in this population (where p is the frequency of the dominant allele). p = 110, q = 90 p = 20, q = 80 p = 0.45, q = 0.55 p = 0.55, q = 0.45 p = 0.2, q = 0.8 p = 90, q = 110
In a population of 500 individuals in Near East, the frequencies of the dominant and recessive alleles for autosomal recessive genetic disease PKU are 0,89 and 0,11 respectively. A is used to indicate the dominant allele, a is used to indicate the recessive allele. Assuming random mating, what are the expected genotype frequencies?
p + q = 1 p2 + 2pq + q2 = 1 p is the frequency of the dominant allele q is the frequency of the recessive allele p2 is the frequency of homozygous dominant genotype q2 is the frequency of homozygous recessive genotype 2pq is the frequency of heterozygous genotype Within a population of roses, the color red (R) is dominant over the color white (r). 40% of all the roses are white.a)The percentage of roses in the population that are heterozygous b) The frequency of homozygous dominant individuals =
