This type of experiment, where members of an outbred populations are introduced to an inbred population as mating partners, is sometimes called a “genetic rescue”. How might measuring the average heterozygosity at a number of loci in the Swedish snake population allow you to test whether the introduced snakes had actually bred successfully with the inbred Swedish snakes?

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 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.

Assume you are studying a population of fire toads and want to predict what happens after a selection event. There is a freeze event. Before the freeze event you measured body size and found the average body size was 50 grams. After the freeze event you measured the surviving toads and their average body size was 70 grams. Based on your previous studies you know that the narrow-sense heritability is 0.5 What is the response to selection in this population?   a. 5 grams   b. 10 grams   c. 20 grams   d. None of the above

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

For goldfish, solid orange coloring is dominant while orange with black spots is recessive.  A total of 2500 goldfish were stocked in an outdoor pond, 2275 solid orange and 225 orange with black spots.  Since the fish came from a protected, indoor, stable environment, you may assume the stocked population was in equilibrium.  What are the and genotype frequencies in the original stocked population?

Researchers studied the blood types of indigenous populations in the Andes. They used a two-allele typing system (M and N alleles). In one population the genotypic frequencies were: f (MM) = 0.70, f (MN) = 0.20, f (NN) = 0.10. What are the frequencies of M and N alleles for this population? Answer choices f(M) = 0.80 and f(N) = 0.20 f(M) = 0.70 and f(N) = 0.30 f(M) = 0.49 and f(N) = 0.01 f(M) = 0.90 and f(N) = 0.10 f(M) = 0.50 and f(N) = 0.50

What is the chi-square value of the pumpkin population? round up and use four decimal points After doing some crosses and genotyping some individuals, you determined that the number of individuals homozygous dominant for the largest pumpkin allele is 98, 80 are heterozygous for medium size, and 20 are homozygous recessive for small size.

In carnations, the red pigment (RR) is incompletely dominant to white (rr). The heterozygote (Rr) is pink. In a randomly mating field of carnations, 42 plants were red, 178 plants were pink, and 180 plants were white (total =400). What is the best estimate of the allele ferequency, for the red allele in this population?
