After investigating a population, a biologist determined that 16% of the population exhibited the recessive trait. Based on this information, what frquency of individuals in the population are likely heterozygous for the trait? 0.16, 0.36, or 0.48

What is the frequency of the T allele in the current gene pool?   Question 3 options:   0.68   0.435   0.52   0.84

In a population of 100 individuals, there are exactly 16 individuals expressing the recessive phenotype for a trait controlled by a single diallelic locus (i.e. a diploid organism). If the population is at genetic equilibrium, how many heterozygous individuals would you expect to find? 48 36 84 cannot be determined 16

The recessive allele that causes Ellis– van Creveld syndrome when homozygous has a frequency of about 0.07 in the Amish population of Pennsylvania, although its frequency is only about 0.001 in the generalpopulation. How many persons out of one thousand in the Amish population would be expected to have the disease? How many out of one million in the general population?

A gene for flower color in pea plants has two alleles, A and a. Given the following genotype frequencies, which of these populations shows evidence of possible inbreeding? AA-0.38, Aa-0.22, aa-0.40 O AA-0.25, Aa-0.5, aa-0.25 O AA-0.01, Aa-0.18, aa-0,81 O AA-0.12, Aa-0.64, aa-0.24 O AA-0.09, Aa-0.42, aa-0.49

Consider rare disorders in a population caused by an autosomal recessive mutation. From the frequencies of the disorder in the population given, calculate the frequency of carriers (heterozygous individuals). Assume Hardy-Weinberg Equilibrium. Disease or Disorder Frequency: 0.64% 0.2 0.64 0.1472 0.8 If the initial allele frequencies are p = 0.5 and q = 0.5 and allele a is a lethal recessive, what will be the frequencies after one generation? 0.96 0 0.66 0.33 0.25 O 00

A hypothetical population has two alleles for a “B" gene: B1 and B2. In a random sample of 50 diploid zygotes (for a total of 100 alleles), the following genotypes were found: 20 B1B1, 20 B1B2, and 10 B2B2 The above values represent the initial genotype frequencies of zygotes in the population. Let's say that selection acts against the B2 allele, and all 10 individuals with B2B2 genotype die off before reaching maturity (leaving 0 B2B2 individuals). (The number of surviving adults in the population is 40, so the number of alleles is 80). What is the new observed frequency of the homozygous dominant genotype? O A. 0.10 О В. О.70 O C. 0.25 O D.0.50 O E. 0.75

In mice, the waltzing allele (w) that causes the mouse to run in circles due to an inner ear defect is recessive to the non-waltzing allele (W).In an ideal mouse population exhibiting Hardy–Weinberg equilibrium of 150 mice, 50% of the alleles are non-waltzing. What is the frequency of the recessive allele?Record your answer as a whole number percentage.

A gene has two alleles that are associated with body mass in an additive manner. The table below shows the mean phenotype for each genotype, along with the frequency of each genotype in a population. Use this information to answer the following questions.   A1A1 A1A2 A2A2 Mean mass (kg) 50 55 60 Frequency 0.01 0.18 0.81 a)  How much does this locus contribute to additive genetic variation?   b)A second locus (B) has two alleles (B1 and B2), which are also associated with body mass in an additive manner. Each copy of the B2 allele adds 2 kg of mass. The B2 allele is at a frequency of 0.6 in the same population as the A alleles are found. How much does the B locus contribute to additive genetic variation?
