- When a population is reduced to a very small number of breeding individuals, random genetic changes called occur. As a result of these kinds of changes,
- variation in genotypes and phenotypes will probably increase compared with the amount of variation present in the original population TRUE OR FALSE?
- genotypes and phenotypes are likely to occur at different frequencies in both the original and reduced populations TRUE OR FALSE?
- the reduced population will have a higher probability of extinction than a similar but larger population TRUE OR FALSE?
Homework Answers
Genetic drift
False: genotype and phenotype variation is a function of population size and smaller population results is less variation.
True
True.

Two people who are “carriers” of (heterozygous) for Tay Sachs disease marry and plan a family. What is the probability that a child from this union will suffer from Tay Sachs disease. (Recall that this is an autosomal recessive disorder, that is, homozygous recessives have the disease.) a. Zero b. 0.25 c. 0.5 d. 0.75 e. 1.0 6. At Hardy-Weinberg equilibrium, heterozygotes are the most common genotype in the population when- a. b. c. d . p> 0.67 q>0.67 and...

True or False: 1-The structure that joins together the two sister chromatids after replication of chromosomes is called the telomere 2- The phase of the eukaryotic cell cycle during which growth and increase in cell mass occurs following cell division is called G2 phase. 3- The most important feature of mitosis is that both the parent and daughter cells are diploid. 4- The characteristic feature of the centrosome is that it is not duplicated during mitosis so that only one...
Climate change is a threat to the existence of many species.
QUESTION 2 Climate change is a threat to the existence of many species. Which of the following limits to natural selection hinders the adaptation of species to the new climate conditions? The developmental plans of plants and animals are too complex. They cannot cope with the warmer temperatures. Mutations happen so frequently that beneficial alleles change before natural selection can substantially increase their frequency Many species not have gene variants in their gene pool that are beneficial in higher temperatures. Climate change happens so...

In the case of directional selection, if the advantageous allele (b) is recessive and a less advantageous allele (B) is dominant: A. b will be lost in the population because the dominant allele will increase in frequency by natural selection B. b will increase in frequency at the same speed as if it was a dominant advantageous allele, because what matters is the coefficient of selection and not if the allele is dominant or recessive C. b will increase in...

17.You are a geneticist studying the population genetics of Monarch butterflies. You are particularly interested in one gene for which the species has two alleles: B and b. Upon examining the alleles present in 100 individuals, you find that the B allele is very common, with an allele frequency of .6. Therefore, you calculate that there are a total of _______ b alleles present in the population. Group of answer choices A) 60 B) 80 C) 100 D) 120 E)...
