A population consists of 7 mice. For the coat color trait, there are only two alleles: brown (B) and white (b). BB and Bb mice are brown; bb mice are white. In the population's gene pool, there are 7 white alleles (b). a) What is the frequency of the brown allele in the population? ISelect) b) What do you predict the frequency of the bb genotype will be in the next generation if no evolution takes place in the population? I Select) C) The mice live on dark black, volcanic rocks in the Arizona desert and two hawks are introduced into the area as part of wildlife rehabilitation program. You sample the mouse population after the hawk reintroduction and find the following numbers: 24 BB mice, 52 Bb mice, 24 bb mice. Has natural selection by the hawks caused the population to evolve significantly? (Select)

1) In cats, the allele for white fur(W) is completely dominant and will result in cats with all white fur in both the homozygous dominant and heterozygous cases. Suppose you look at 50 cats and notice that none of them are completely white. What's the allele frequency for the white fur allele in this population? 2) In carnations, the allele that makes red pigment (R) in flowers is incompletely dominant. Flowers that are red are homozygous dominant and those are pink are heterozygous. White flowers (r) are the result of the recessive allele. Suppose you look at a field of 100 carnations and notice 42 of the plants produce red flowers, 42 have pink flowers, and 16 produce white flowers. What's the allele frequency for both the red (R) and white (r) alleles?

A population of mealworm beetles (Tenebrio molitor) called the founder generation-consisting of 150 Black (MM) individuals, 100 Brown (Mm) individuals and 250 Orange (mm) individuals-is established on a remote region of Puerto Rico. Mating within this population occurs at random, the three genotypes are selectively neutral and mutations occur at a negligible rate. (a) What are the frequencies of alleles M and m in the founder generation? Frequency of allele M= Frequency of allele m= (b) Calculate p2, 2pq, q2 and the expected number of MM individuals, Mm individuals, and mm individuals in the population, assuming that the population is in Hardy-Weinberg equilibrium

If the frequency of an allele at a locus of interest is 0.57, and we know there are only two alleles at this locus, what must be the frequency of the other allele?

Consider a greenhouse with 500 carnation plants. 280 plants are homozygous for the red allele (RR), 120 plants are heterozygous (Rr), and 100 plants are homozygous for the white allele (rr).  What is the frequency of the red allele? What is the frequency of the white allele?

Polydactyly (being born with more than 5 fingers or toes) is caused by a dominant allele of a single gene. If the frequency of the recessive allele is 0.9 (or 90%) in a certain population, what percentage of the population would you expect to be heterozygotes? Assume this population is in Hardy-Weinberg equilibrium. Note: In reality, there are other causes of polydactyly when it is accompanied by other disorders, so this problem is an over-simplification.   18%         1%         90%         81%

A farmer performs truncation selection to try to increase the weight of peaches in his orchard. Which statement correctly describes a possible outcome of this selection? a) If peach weight is not heritable, the average weight in the next generation will increase. b) If peach weight is heritable, the average weight in the next generation will increase. c) The average peach weight will decrease due to this inbreeding. If peach weight is heritable, the average weight in the next generation will decrease.

If 120 of 200 alleles are dominant alleles, then what percentage of the alleles are dominant alleles?  A-12% B-40% C-60% D-120% What percentage of the alleles are recessive alleles? E-8% F-40% G-60% H-80% Which of the terms of the Hardy-Weinberg equations represents the frequency of the recessive allele in the gene pool? A-p^2 B-p C-2pq D-q^2

After graduation, you and 19 of your closest friends charter a plane to go on a round-the-world tour. Unfortunately, you all crash land safely on a deserted island and you start a new population totally isolated from the rest of the world. Two of your friends are heterozygous for the recessive cystic fibrosis allele (c). Assuming that the frequency of this allele does not change as the population grows, what will be the incidence of cystic fibrosis on your island?  In percentage provide summation.

In hamsters, there is a dominant allele (S) for smooth fur and a recessive allele (s) for spiky fur. A unique characteristic of these alleles is that the heterozygote (Ss) has its own phenotype - rough fur. In this way, we can determind the number of heterozygotes in the population. In a population of 1000 hamsters, 390 have smooth fur (SS), 470 have rough fur (Ss) and 140 have spiky fur (ss).    Question: The expected number of smooth fur hamsters (SS) in the next generation of 1000 hamsters is:   Question 3 options:   0.390   470   625   390
