Question

1. A researcher sets up 100 replicate population cages. Each is founded with 20 Drosophila melanogaster individuals, drawn from a population that is polymorphic for the L1 and L2alleles at a neutral pseudogene locus L. After many months the L1 allele is fixed in 11 of the cages and the L2 allele is fixed in 89 of the cages. Estimate the frequencies of the L1 and L2 alleles in the original population from which these cages were founded.

2.

In many polygynous songbird species, such as wrens or red winged blackbirds, a single male holds a territory and mates with several females on that territory. In monogamous species, such as cardinals and blue jays, mated pairs typically hold a territory and males mate with only one female. In comparably sized populations, do you expect drift to have a stronger effect in polygynous species or monogamous species? Explain your choice.

Answer 1

Aas g) Yes. The size of population depends in the mating system and generation time. In small population, monogamous species are more genetically diversed than polygamous species. The success of mating variance is large in polygamous than monogamous. Polyganous individuals mates as possible to maximise the breeding success. Thus, they shut down population divergence. High breeding dispersal increase gene flow in polygamous species. They have significantly less genetic structure and weak isolation than monogamous. Sexual dimorphism and size differences gives males an advantage to be donunant, to increase fituess in Polygamout. This makes polygambers bied species are less genetically deversed. Thus, drift have a stronger effect eu polygamous and monogamous speues. Note :- As per HomeworkLib rules 1 part is answered Pleast Rate my Answer
