In fruit flies, the allele for vestigial wings is recessive to the allele for normal wings. in a generation of fruit flies, 18 males and 15 females with vestigial wings are produced, and 43 males and 44 females with normal wings are produced. which of the following is the best conclusion you can make about the parents of this generation? both parents were heterozygous for wing type. one parent was heterozygous for wing type and the other was homozygous with normal wings. both parents were homozygous with normal wings. one parent had vestigial wings and the other was heterozygous for wing type.

Humans are believed to have evolved in coastal regions in east africa. the region had an abundant supply of fish for early humanoids to eat. when scientists analyze the fads gene they see an interesting pattern. people whose families have lived in this area of east africa for generation show a high level of diversity in alleles for the fads gene. conversely, people whose families had migrated inland a moderate distance from sources of fish showed a much lower diversity for fads gene alleles. additionally, the fads alleles found in people whose family has lived inland for generation are almost all gene alleles which produce fads proteins with a high level of function and activity. how do anthropologists explain this?
