A population of frogs on a remote pond consists of 75 individuals. The frequency of the luminous color recessive allele (l)  in this resident population is 0.70. in this pond population. Due to flooding, 25 frogs from a neighboring swamp are introduced into the pond. In the swamp population, the frequency of the l allele is 0.15. What is the expected frequency of the luminous color l allele in the new frog population in the pond?

L11: Which is NOT true of most bacterial DNA? A.It consists of a single circular DNA molecule with negative supercoils B.It appears as a distinct clump called a nucleoid. C.It is wrapped around histone proteins. D.It exists in a series of twisted loops. E.It is usually circular

A population of bacteria is exposed to a new antibiotic. After several days, most of the bacteria die, but a few survive and continue to reproduce. Eventually, the entire population becomes resistant to the antibiotic. What is the most accurate explanation for this outcome?

In a population of imaginary creatures called flufflins, the gene for fur texture has two alleles: F (smooth) and f (spiky). The three genotypes and their frequencies in the population are: FF = 0.25 Ff = 0.50 ff = 0.25 What is the frequency of the F allele in this population?

L14: You labeled the light gray and dark gray strands based on synthesis direction. The light gray strand is being synthesized toward the left side of the bubble, complementary to the red (top) strand. Which of the following correctly indicates the direction of synthesis for this light gray strand?  

L5: One form of red/green color blindness is inherited as an X-linked recessive trait. Assume a homozygous-normal woman has children with a colorblind man. Are there any of the offspring from this cross colorblind?

Part A. What is the frequency of the recessive allele that causes the condition? (type only numbers, no letters, for example 1.3)

Tarsanemia is a (made up) rare, autosomal recessive human disease caused by a mutation in the tar1 gene. In the general population, about 1 in 40,000 individuals is affected by Tarsanemia. What would be the expected frequency of individuals affected by the disease if siblings mate?

L9: An individual is heterozygous for genes A and B and has the following genotype: Which gametes are expected to be produced from that individual (assume genes A and B are unlinked)? A, a, B and b AA, AB, BB and bb AA, Aa, aa, BB, Bb and bb AB, Ab, ab and aB

L12: Which statement is true regarding negative supercoiled DNA?
