Solved in 2 steps
- Ancient societies used knowledge that traits are heritable in domesticating animals and developing agricultural crops. What might account for the failure to recognize that the same processes operate in humans?When artificial selection is practiced over many generations, it iscommon for the trait to reach a plateau in which further selectionhas little effect on the outcome of the trait. This phenomenon isillustrated as shown. Explain why it occurs.A(n) _____ makes a species better suited to its environment.a. homologous traitb. adaptationc. analogous traitd. mutation
- TRUE or FALSE: I expect for genetically identical animals thta have been reared in similar conditions to have a similar SD for any paraeter that I decide to measure compared to genetically diverse animals that have been grown in a variety of natural environments.An individual and a population has certain characteristics.Name these attributes with definitations.Sexual selection occurs whena. one sex has a higher fitness than the otherb. a species exhibits sexual dimorphismc. there is a male dominance hierarchy and only the alpha male reproduces. d. There is monogamous mating.e. A trait is favored by one sex such that individuals of the opposite sex possessing that trait have an increased likelihood of reproducing.
- evolutionary trade of is when a trait is at an advantage in a context a) explain how the evolution of the different shades of color is an example b) what evidence can you use to support this ideaa statement of how sexual selection differs from natural selection has to be a statement that is wrrtien in a essayConsider rare disorders in a population caused by an autosomalrecessive mutation. From the frequencies of the disorder inthe population given, calculate the percentage of heterozygouscarriers: 0.10
- Different species of crickets have distinct songs, andthey use these songs for mate recognition. Researcherscrossed two species of Hawaiian crickets (Laupala paranigra and L. kohalensis) whose songs are distinguishedby pulse rate (the number of pulses per second; Shaw etal., Molecular Ecology 16, 2007, 2879–2892.) Then, theymapped QTL in the F2 population derived from thiscross. Six autosomal QTL were detected. The mean traitvalues (pulses per second) at the three genotypic classesin the F2 for each QTL are shown in the table below,where P indicates the L. paranigra allele and K indicatesthe L. kohalensis allele.a. Calculate the additive (A) and dominance (D) effectsand the D/A ratio for each of the six QTL.b. Which of these QTL shows the greatest amount ofdominance?c. Which of these has the largest additive effect?d. The mean pulse rate for L. kohalensis is 3.72, and it is0.71 for L. paranigra. Do all six QTL act in the expecteddirection with the L. kohalensis allele conferring a…T/F: The concept "biological determinism" was the claim that: one's cultural superiority (or inferiority) was determined by a biological featureFor selective breeding to be successful, the starting populationmusta. have genetic variation that affects the trait of interest.b. be very large.c. be amenable to phenotypic variation caused by environmentaleffects.d. have very little phenotypic variation.
