Concept explainers
In a particular species of flower, C1 codes for red flowers, C2 codes for white, with the heterozygous individuals being pink.
A. In the frequency of pink individuals in the population was .7126, would you be able to estimate the frequencies of the individuals alleles in the population? Why or why not?
B. If the frequency of red individuals in the population was .329, what would the estimated frequency of pink and white individuals be in the same population?
The Mendenlian principles of inheritance, sometimes fails to respond to certain situations. The inheritance pattern in which both the characters produces a mixed form is known as incomplete dominance.
Hardy weingberg principle is a population genetics principle which states the flow of the frequency of alleles from one generation to another.

- In a population of 344 individuals, a locus has two alleles: T and t. If 125 individuals have the tt genotype, and the locus is at Hardy-Weinberg equilibrium, what is the frequency of the TT genotype? Round your answer to the second decimal place.arrow_forwardImagine that in squirrels, the gene for brown coat is coded by two alleles, D for dark brown and d for light brown. In a population of squirrels in Central Park, you identified 251 DD, 182 Dd , and 117 dd. What is the frequency of the light brown, d allele? Please use and round to four decimal points.arrow_forwardThe number of homozygous hitchhiker thumb individuals (a dominant trait) in a population of 100 is 9 while heterozygote's number 48. Calculate the frequency of both alleles and identify if this population is in Hardy-Weinberg equilibrium (show your work).arrow_forward
- 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 0.60arrow_forwardConsider a finite population in which individuals carry two alleles at a particular genetic locus. One of the two alleles is currently at a frequency of 0.42 in the population. If the locus is neutral, such that neither allele confers a fitness advantage, what is the probability that this allele is eventually lost from the population?arrow_forwardColor in a species of minnow is determined by a single locus with two alleles: D and d. DD individuals are dark, Dd are intermediate, and dd are pale. In a population that is in Hardy–Weinberg equilibrium, we count 74 pale minnows out of 202. How many minnows do you expect to be dark?arrow_forward
- There are 350 dominant homozygotes, 75 heterozygotes, and 40 recessive homozygotes in a population. How many dominant and how many recessive alleles are in this population? What would be their respective allele frequencies?arrow_forwardIn a population of 500 fruit flies, 250 are genotype RR, 100 are genotype Rr and 150 are genotype rr. Determine the allele frequencies for this gene in this population. Remember that the frequencies should add to 1. Please show your work.arrow_forwardAssuming a population is in Hardy-Weinberg equilibrium, an increase in the frequency of the p(A) allele from 0.6 to 0.9 would result in which of the following outcomes? a. A decrease in the number of homozygous dominant individuals within the population b. A decrease in the number of homozygous recessive individuals within the population c. An increase in the number of homozygous recessive individuals within the population d. An increase in the number of heterozygotes within the population e. No change in genotypic frequency within the populationarrow_forward
- You are investigating the gene for eye color in a population of Hawaiian Drosophila flies that is in a Hardy-Weinberg equilibrium. You then discover that the frequency of allele E in this population is 0.45. What are the expected genotype frequencies in this population? O A. EE = 0.55, Ee = 0.0, ee = 0.45 B.
