Answer:
O founder's effect
Explanation:
A founder effect can be defined as the loss of genetic variation when a new population is established from a few individuals. This process is known to increase the frequency of particular gene variants (alleles) at different <em>loci</em> when they are selectively neutral (or nearly neutral), and thereby such genes are fixed by genetic drift (i.e., through the random sampling of founder individuals). Interestingly, it has been discovered that the majority of South American and Central American Indians are nearly exclusively in the O blood group, which has been further associated with random genetic drift and a founder effect.
Answer:
Yes
Explanation:

Answer:
i). Dominant Allele.
ii). Recessive Allele
Explanation:
A dominant allele completely dictates the appearance or phenotype of heterozygotes. One allele is said to be dominant over another if a heterozygous individual bearing the allele has the same appearance as an individual who is homozygous for it.
A recessive allele is one who phenotypic expression is completely masked in heterozygotes by the presence of a dominant allele.
