What describes the phenotypic plasticity of an organism best? O the degree of which individuals can change over time by altering their genotype O the effect of variable environment on the genotype of an organism O the variation of the target phenotype for a given genotype in different environments O the change of a phenotype due to ingestion of detrimental plastic material (as for instance plastic straws by sea turtles). O the degree of which a given genotype is adapted to a particular environment

Which of the following scenarios shows the founder effect? O Two different species of frogs mate with each other and create a triploid hybrid. This hybrid can produce viable offspring via parthenogenesis OA small group of salamanders moves away from the large population. By chance, this newly established population contains only individuals with the same genetic mutation O Butterflies with a foul taste are left alone by predators, while those without the foul taste are eaten O An avalanche wiped out 90% of a snow hare population, by chance, only the dark brown hares survived O Cichlid fish in lake Tanganyika were under the influence of different microhabitats and evolved based on the local environmental conditions
An anthropologist discovered that Papa new Guyana tribes that had given up the customs of cannibalism also had an avid aversion to grapefruit . The ability to taste the horridbitterness of PTC present in grapefruit respectively human brain tissue is due to a dominant alial. A small tribe of 637 Papa New Guinea hens was tested by a population geneticists the following results were displayed. Tasters Non-tasters Total Males 171 86 257 Females 337 43 380 Total 508 129 637 A.)Calculate the recessive ally of frequency (i)among males (ii) among females B.) calculate the amount of individuals being homeless sigus for tasting PTC, also the number of heterozygotes individuals and non tasters within the tribe. C.) another tribe still being cannibals trust past the territory of the other tribe they were captured killed and feasted on the brains of 50 PTC tasting males respectively 19 females as to access their abilities seen as a gift from gods.…
How are these examples of phenotypic plasticity? 1. Haman weight 2. UV exposure 3. Flower color/pH
69)At the genetic level, what would indicate that an allele has experienced positive selection he allele is recessive The allele is dominant The allele has a higher frequency than expected from the Hardy-Weinberg Principle All of the options Most copies of the allele are found in heterozygote individuals.
Suppose we know both parents are heterozygous for a trait. Which would we predict if they have a lot of kids? O The kids may be homozygous for the dominant trait, homozygous for the recessive trait, or heterozygous. O All kids will be heterozygous too. All kids will be homozygous - half for the dominant trait, half for the recessive trait. O No predictions are really possible.
The pads on cats' feet are either made of rubber (R) or metal (r). R is dominant. Their whiskers can either form a mustache (M) or beard (m). M is dominant. Cat RrMm mates with cat Rrmm (note that the parents' genotypes are NOT identical), and they have kittens: What fraction do you "еxpect?" What # of Here is what you kittens do you "expect?"* "observe." Rubber feet/mustache Rubber feet/beard Metal feet/mustache Metal feet/ beard * Hint: The number you expect is based on how many total kittens there were; you'll have to add up all the actual 14 15 10 kittens in the next column yourself because I didn't do it for you. a) Fill out the blank columns b) What is the Chi Square formula? (for partial credit in case you miss the answer for part d). c) how many degrees of freedom in this case?

How can you recognize codominance? The alleles affect more than one trait. O The trait exhibits continuous variation The heterozygote expresses the phenotypes coded for by both alleles O The phenotype of the heterozygote is intermediate between the phenotypes of the homozygotes. 梦 24 近
