Question

Question 18 1 pts Sunflower hybrids resulting from crosses between wild sunflowers and their domesticated relatives have high rates of survival. This would seem to suggest that the hybrids have a high fitness. However, before reaching this conclusion, you should next examine O whether hybrids have a higher mutation rate than their parents. 0 whether there is evidence of balancing selection in the parents. O the number of offspring produced by hybrids. 0 the rate at which wild migrants enter populations of domestic sunflowers

Explanation / Answer

Please find the answers below:

Answer 1: Choice 2 (although the hybrids show more fitness to the environment, it is crucial to note whether the parental gene pool is maintained throughout these species since the total allelic pool is required to be preserved. If this does not take place, the total gene pool will undergo mutation and the wild type variety would be slowly eliminated from the environment)

Answer 2: Choice 1 (Transmission genetics deals with the individual organisms of a population and their pattern of inheritance of a set of alleles thus relating to their heridity from one generation to another. On the other hand, population genetics deals with the total frequency of presence of an allele in a given set of population)

Answer 3: Choice 2 (Hardy-Weinberg equilibrium is based upon the assumption that the population undergoes random mating, thus if a population undergoes selected mating or non-random mating, it does not follow Hardy-Weinberg equilibrium)
