Imagine a huge population with a gene that has ten functionally equivalent, neutral alleles. a small but genetically representative group of individuals from the population is transported to an island, forming a small population. what will likely happen over time and why?

In a population of 500 individuals, 70% are homozygous dominant for the A allele. What percentage of the population is heterozygous for the A allele? a) 10%   b) 20%   c) 30%   d) 40%

describe one way a gene drive has been created to change a natural population, and describe how it works in as much detail as you can

In sexually reproducing species, each individual begins life with DNA inherited from both parent organisms. , Apply this idea to what occurs when organisms of two species that have homologous chromosomes mate and produce ( F1 ) hybrid offspring. What percentage of the DNA in the F1 hybrids' chromosomes comes from each parent species? As the hybrids mate and produce F2 and later-generation hybrid offspring, describe how recombination and natural selection may affect whether the DNA in hybrid chromosomes is derived from one parent species or the other.

In a certain population of finches, a single gene controls beak length. There are two possible alleles: S, which leads to a short beak, and L, which leads to a long beak. Individuals with the genotype SS will have a short beak, individuals with the genotype LL will have a long beak, and individuals with the genotype SL will have a medium-length beak. Scientists measure that in this population of 1,128 total birds, 321 birds have short beaks, 562 have medium-length beaks, and 245 have long beaks. Ten years later, the measurements are repeated. This time, there were 1,346 birds in the population. 452 have short beaks, 699 have medium-length beaks, and 195 have long beaks. Based on the data collected 10 years later, is this population of finches currently evolving? How do you know?   A. yes because more individuals in the population exhibit the SS genotype than would be expected if the population was in Hardy-Weinberg equilibrium   B. no because the number of individuals that…

A mountain region has a population of 5,000 mountain goats. You score these animals for the R locus and find that this locus has two alleles, R (dominant) and r (recessive). 3200 individuals are homozygous dominant, 1,600 are heterozygous, and 200 are homozygous recessive.  a) Calculate the allele frequencies for this population. Show your work.       b) Calculate the observed genotypic frequencies for this population. Show your work.         c) Calculate the expected genotype frequencies if the population is in Hardy-Weinberg equilibrium. Show your work.         d) Does this population appear to be at H-W equilibrium? Why or why not? (You do not need to analyze this statistically).

A scientist is interested in the ability of a small population of fish endemic to the streams of Mauna Kea in Hawaii to evade predators. She notices that some fish within the population are black (BB or Bb), while a smaller subset seems to have an albino mutation and are white (bb). She observed the population and through sampling quantified the number of fish that were black or white, and the population size. These results are listed below. Observations: a. Population size = 5,000 fish total b. Black Fish: 72% c. White Fish: 28% Calculate the following: Remember to use the algorithm described with the sample questions in the introduction to the lab manual. Please round answers to the nearest hundreth (0.00 format) a. Frequency of homozygote dominant fish b. Frequency of heterozygote fish c. Frequency of the B allele  d. Frequency of the b allele  e. Number of fish who are heterozygotes in the population f. Number of B alleles in the populatio
