seedcracker finches from Cameroon, small- and large-billed birds specialize in cracking soft and hard seeds, respectively. If ng-term climatic change resulted in all seeds becoming hard, what type of selection would then operate on the finch population? disruptive selection stabilizing selection directional selection uld onorate because the nonulation is in Hardy-Weinberg equilibrium.

Question 7 Identify the type of selection represented by this diagram Sedeconaganstanetene Pepulaon whersecton Orginal ton directional selection habitat isolation sexual selection stabilizing selection disruptive selection

A small portion of a population migrates to an isolated island. Its genotypic frequencies are 0.8 AA, 0.1 Aa and 0.1 aa. These individuals start a new population on this island. What violation of Hardy-Weinberg Equilibrium is being described here? 00 Genetic Bottleneck Founder Effect Natural Selection Nonrandom mating

Human adult males generally have deeper voices than do adult females, which is the direct result of higher levels of testosterone causing the enlargement of the larynx. If one excludes the involvement of gender in the situation, then the pattern that is apparent in the fossil record is most similar to one that should be expected from what type of selection? directional selection stabilizing selection asexual selection disruptive/diversifying selection

Answer the following multiple-choice questions: 1) Which of the following DOES NOT alter a population’s genetic composition?  random mating  natural selection  Inbreeding  Gene flow from migration  Genetic drift  2) If a new species of frog were discovered, which of the following characteristics would be BEST for determining its systematic relationship with other amphibians.   The DNA sequence of its mitochondrial genes  The diploid number of its chromosomes The number of eggs produced by the females  The adult body size of the males  The type of habitat in which it lives.    3) Which pair of anatomical structures is alike because of shared ancestry?  flipper of a dolphin v. the pectoral fin of a shark  wing of a bird v. wing of a butterfly flipper of a dolphin v. the wing of a bat  shell of an oyster v. shell of a turtle  tusks of an elephant v. horns of a bull.    4) Which of the following does NOT increase the amount of genetic variability?  fertilization during sexual…

In 1959 Daniel Yuh set up a long-term study of cataloging the blood types of a group of foragers in the Brazilian rainforest. In 1959 he found there were no individuals with blood type B. Three generations later, after this group had begun exchanging mating partners with another group, there were several members with blood type B. A-mutation B-natural selection C-gene flow D-genetic drift

which of the following  would be sufficent for the hardy-weinberg equations to accurately predict geontype frequencies from allele frequenceies. - p+q = 1 - the population is not evolving due to natural selection  -the population is not evolving due to any of the conditions that disrupt hardy-weingberg - the population is infinetely large

In each experiment, what was the variable that differed??

Cana a change in the physical enviroment of a population result in evolution by natural slection?(hint: remember the peppered moth's camouflage and color changes of tree bark due to pollution)
