Say you have a lab population of 1000 dragonflies that is in Hardy Weinberg equilibrium. Body color is determined by a single gene with 2 alleles. The white body color phenotype is due to the homozygous recessive phenotype. Out of the 1000 dragonflies, 250 are white. Heterozygous and homozygous dominant individuals are green. How many of the 1000 dragonflies are heterozygous?

A meadow is home to a population of plants of a particular species. Among these individuals are 125 plants that have red flowers and 375 plants that have white flowers. The allele of the flower color gene that produces red flowers (R) is completely dominant over the white flower color allele (r). If a plant with red flower color is crossed with a plant that produces all white flowers, what is the probability that the offspring will include plants that have white flowers? Group of answer choices a. 50% chance b. 75% chance c. 0% chance d. 25% chance e. There is not enough information to say.
Assuming a Hardy-Weinberg equilibrium, 21% of a population is homozygous dominant, 50% is heterozygous, and 29% is homozygous recessive. What percentage of the next generation is predicted to be homozygous recessive? Group of answer choices 53% 29% 42% 58%

You sample a population of butterflies and find that 42% are heterozygous for a particular gene. What would be the frequency of the recessive allele in this population? Group of answer choices 0.42 0.28 0.58 0.21 Allele frequency cannot be determined from this information.
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? Group of answer choices 0.26 0.56 0.23 0.27
If 60 percent of the loci in a gene pool are dominant for the hair color trait H, and 40 percent are recessive (h), then according to Hardy-Weinberg theory, what percentage of the individuals in the population will be recessive for this trait (hh)? A. 16 B. 40 C. 36 D. 24
A population of rabbits may be brown (the dominant phenotype) or white (the recessive phenotype). Brown rabbits have the genotype BB or Bb. White rabbits have the genotype bb. The frequency of the BB genotypre is .35 What is the frequency of the heterozygous rabbits? What is the frequency of the B allele? What is the frequency of the b allele?
Cystic fibrosis is a genetic disease mostly affecting people of European descent that is caused by a recessive allele. You sample 1000 people for this allele and find 772 homozygous normal individuals, 221 heterozygotes, and 7 people homozygous for cystic fibrosis. Is this population in Hardy-Weinberg equilibrium?
In a population of snails, a locus affecting shell color has 2 alleles. The D allele produces a dark shell, while the d allele produces a white shell. Heterozygote individuals (Dd) have a yellowish shell. In a sample of 150 snails, 47 snails have a white shell, and 12 have a yellow shell. What is the frequency of the D allele? Round your answer to the second decimal place (0.00)
