Quiz 5 A up of small populators experiences high ma rartal (-20 % of nom a mitple gene that is thought to be involved with water retention has an average change in trequency a negative change. This would most probably be an example of b) migraton e) drift years. At the end of the period, a -0 4 with all populations than smaller eyespots. He paints over the dameter eyespots on 40 and 0 5 cm dameter hypothesizes that larger eyespots on the wings of a buterty species are better protection against predation by birds eyespots of 80 buterties with white paint (matching wing background) and paints 1em e amount of wing damage of the two groups for 3 weeks (all butterties dead) He finds a signiicant difterence in spots on the other 40. He r monitors the survivorship and he two groups, those with the larger eyespots have over 50% less damage compared to hose with the smaller eyespots. He aiso finds that the heritability of eyespots is 1.0. He concludes that selection for eyespot size is present in the population, but a reviewer of his work rejects his premise because he did not demnsthat a) eyespot size was variable b) more offspring were bom than survive to reprodace c) a difference exists between those that survive and those that do net d) eyespot size was inherited -the table below at which temperature does the genotype have its highest ftness? hnte 5 4. In a beetße population, two phenotypes are present spotted (green with brown spots) and unspotted (green). A single gene locus the two phenotypes Currently the only predators in the dffer in chemical odors and are eaten in enters the community and finds the beetles quite tasty Birds are visual predators and the unspotted chemical cues to search for their beete prey. The two phenotypes do not equal numbers A bird species phenotype is easier to locate on the your understanding of evolution, which is ikely to happen? unspotted individuals will mutate to become spotted b) The spoted phenotype will increase because spotted individuals have higher survivorship and will leave more spoted offipring c) The spotted phenotype will not change because the unspotted allele d) The spotted phenotype will not change because unspotinddals well have more offspring to compensate for lewer 5. In which of the following populations would you most likely be able to predict the change in genotype frequency in the next has afitness 3.1, genotype B has a ftness 2.0, and the population size 20 b genotype A has a fitness 3.1, genotype B has a fitness 3.05, and the population size 20. e) genotype A has a fitness 3.1, genotype B has a ftness 2.0, and the population size 20,000 di genotype A has a fitness 3.1, genotype B has a ftness 305, and the population size 20,000 lar 6.A group of poultry sclenists is interested in selecting for larger egg size in a breed of chickens (Nankin) with small eggs. They obtain chicks from two dfferent sources and select those females with average egg size larger than the average to breed. The chicks were raised and average egg size was measured when after they were adults The results are summarized in the table below mean egg size (g) mean egg size ofmean egg size in next generation (g) 456 44.9 44.0 44.8 44.4 42.7 Remember R h'S where R (mean next generaton-mean before selection) and S- (mean after selection-mean before Which population has the higher heritability for egg size under the breeding conditions?Explanation / Answer
Q-5 Ans. genotype frequency in a population is the number of individuals with a given genotype divided by the total number of individuals in the population. genotypic frequency of all above options are a=0.1 ; b=0.1525 ; c=0.0001 ; d= 0.0001525 option-b has more genotypic frequency so it is the answer
