a hypothetical population which is in Hardy Weinberg equilibrium, the frequency for a recessive allele is 20%. What percentage of the population would be expected to show the dominant trait in the next generation?

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?

In a population of frogs in Hardy-Weinberg equilibrium, a single gene controls the skin lor. Green is dominant to brown. You sample the frog's gene pool, and find that the frequency of the daminant green allele is 0.678. What is the froquency of the recessive allele? What is the frequency of homozygous dominant frogs? What is the frequency of heterozygous frogs? What is the frequency of homozygous recessive frogs?

In mice, albinism (g) is recessive to grey coat colour (G). The fur colour in mice is a single gene trait controlled by two alleles.In an ideal mouse population exhibiting Hardy–Weinberg equilibrium, a grey mouse mated with an albino mouse. Over the course of several months, 55 pups were born.If the grey allele has a frequency of 0.618, which of the following rows identifies the number of the grey and albino alleles in the population of 55 pups? Group of answer choices Grey Allele Albino Allele 34 21 Grey Allele Albino Allele 68 42 Grey Allele Albino Allele 42 68 Grey Allele Albino Allele 21 34

Consider a population of 150 mice on an island, with allele frequencies B = 0.20 for brown coat colour, and b = 0.80 for white coat colour. Brown (B) is dominant to white (b) and the population is in Hardy-Weinberg equilibrium. Twenty-five homozygous brown mice from the mainland float to the island on an uprooted tree after a storm.  What are the genotype frequencies before migration?  What are the allele frequencies after migration?  Now, suppose the twenty-five brown mice float away again on another tree without breeding, and the island is back to its original state. Allele frequencies on the island are back to B = 0.20, b = 0.80. On the continent, there is a large population of many thousands of mice, with allele frequencies B = 0.80, b = 0.20. One year, human ships begin moving back and forth between the island and the continent, and occasionally a mouse comes along for the ride, and stays and breeds. Equal numbers of mice ride in each direction. The shipping trade continues…

In an imaginary three-toed sloth population at Hardy-Weinberg equilibrium, where T = three toes and t = four toes, the frequency of the recessive allele is 0.14. What percentage of the population has three toes? Assume complete dominance.

What does the Hardy-Weinberg model tell us about the factors that can change allele frequencies in populations and result in evolution? What are those factors, and what effect will they have on a biological population?

If the population is in Hardy-Weinberg equilibrium, what is the expected (projected) frequency of heterozygous cats in the next generation?   Question 4 options:   0.68   0.89   0.435   0.84

If gene A/a is not in Hardy-Weinberg equilibrium due to natural selection such that individuals with the genotype AA have a fitness value of 1.0, heterozygotes have only slightly reduced fitness at 0.9, and individuals with the genotype aa have a fitness value of 0.6, what kind of change in allele frequency would you expect to see over time assuming you start with equal frequencies of the 2 alleles?

the frequency of allele a is 0.45 for a population inhardy-Weinberg equilibrium. What are the expectedfrequencies of genotypes AA, Aa, and aa?
