A farmer have 2000 cows. A total of 1500 of the cows are browh coated and the rest are white coated. Allele B for the brown coat is dominant, while allele b for the white coat is recessive: Assume that the population of the cows is at genetic equilibrium and bred randomly. Calculate the frequency for the dominant and recessive alleles of the population. i. Calculate the genotype frequencies in the F1 generation if the cows are left to breed randomly. ii. If the farmer adds another 1000 homozygous dominant brown cows into the populations, calculate the new dominant allele frequency. ii. iv. State three conditions for the Hardy Weinberg equilibrium to be achieved.The reason spontaneous mutations do not have an immediate effect on allele frequencies in a large population is that: a. mutations are random events, and mutations may be eitherbeneficial or harmful. b. mutations usually occur in males and have little effect oneggs. c. many mutations exert their effects after an organism hasstopped reproducing. d. mutations are so rare that mutated alleles are greatlyoutnumbered by nonmutated alleles. e. most mutations do not change the amino acid sequence of aprotein.- Gramm X P Pearson X G translat x 7 Traduct x Textboc x b Bongo x b Virt X Unit 58 3144/viewContent/112835/View pruce Harbor, Mai..

The doctor suspects that, for some reason, blood sugar levels are abnormally low. But testing indicates that blood sugar levels are normal. Further testing reveals that sugar levels inside cells are indeed abnormally low. a. What could be going on here? Why might the sugar levels inside the cells be low even though in the bloodstream they are normal? State in terms of genes. b.

In a sample from a population of frogs, 68/212 male frogs are "short callers." If "short callers" are homozygous recessive, what is the frequency of the dominant allele in this sample? 1. 0.67 2. 0.32 3. 0.57 4. 0.43. A chicken breeder is working with a population in whichthe mean number of eggs laid per hen in one month is 28and the variance is 5 eggs2. The narrow-sense heritabilityis known to be 0.8. Given this information, can the breeder expect that the population will respond to selectionfor an increase in the number of eggs per hen in the nextgeneration?a. No, applying selection is always risky and a breedernever knows what to expect.b. No, a breeder needs to know the broad-senseheritability to know what to expect.c. Yes, since the narrow-sense heritability is close to1 (0.8), then we would expect selective breeding couldlead to increased egg production in the next generation.d. Yes, since the variance is greater than 0.e. Both c and d are correct.SEE MORE QUESTIONS
