A hypothetical species of plant has flowers whose color is controlled by a single gene with two alleles, blue (B) and yellow (Y), where blue is dominant and yellow is recessive. A population of 2430 of these plants includes 190 plants with yellow flowers. Assuming that the population is in Hardy-Weinberg equilibrium, what is the frequency of the yellow allele?

You have two types of garden gnomes in a population. The majority are travelers, but some are home-bodies. This trait appears to be controlled by a single gene, which displays normal Mendelian complete dominance. The dominant allele is traveler (T) and the recessive allele is home-body (t). The frequency of the dominant allele is 0.70. If this population is in Hardy-Weinberg equilibrium, what is the frequency of heterozygotes in the population? Explain how you arrived at your answer.

Consider a population of T00 plants, In Hardy-Weinberg equibrium (p+ 2pg + 9=), In which flower color is determined by two alleles at a single gene. Homozygotes are eniher white or red, and heterozygotes are pink. Suppose a scientist counts 36 red flowers, 48 pink flowers, and 16 white flowers in a population of this plant. What is the frequency of the allele that confers red flower color? 0.16 0.36 0.50 0.60

The next several questions refer to the data given in this problem. You sample a population of leafhoppers and genotype 250 individuals at a polymorphic locus with two alleles. You obtain the following numbers: AA = 68 individuals Aa = 54 individuals aa = 128 individuals What is the frequency of the A allele? (You may round your answer to 2 decimal places) What is the expected number of individuals with the AA genotype if the population is in Hardy Weinberg equilibrium? (You may round your answer to the nearest whole number) What is the expected number of individuals with the Aa genotype if the population is in Hardy-Weinberg equilibrium? (you may round your answer to the nearest whole number)
