Answer:
Predict the possible genotypes and phenotypes percentages for the
offspring produced from the cross below if albinism is recessive in
humans. Albino male x Heterozygous female
aa X Aa = Aa, aa, Aa, aa
Explanation:
From the crossing above, it is right to say that albinism and non-albinism occur in a 50-50 ratio i.e 50% each. The genotype shows that there is 50% homozygous recessive albinism while there is also 50% heterozygous non-albinism. The phenotype reflects that there no dominance of albinism or non-albinism, they both share equal phenotypic characteristics

Answer:
c. Directional selection
Explanation:
Directional selection is a type of natural selection that occurs when selective pressure favors one extreme phenotype over any other phenotype existing in a population. Only one extreme phenotype is favored over time.
A good example of directional selection is the natural selection that occurs in giraffes, where alleles for long necks were favored against alleles for short necks as a result of selection pressure among the different phenotypes. Over time, giraffes having long necks dominated the population as the distribution of length of neck shifts towards the phenotype for long necks.
