Short pea plants exist in the p1 and f2 generations. what happens to the phenotype in the f1 generation?
a) the allele for short pea plants is absent from the genotypes in the f1 generation.
b) the allele for short pea plant is masked during f1 generation , but i still present in the genotype.
c) the allele for short pea plants in not passed on to the f1 generation

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?
