Answer:
Populations from the Americas started from a founding population with a high frequency of the O allele
Explanation:
Human blood type is determined by three different codominant alleles: IA, IB, and, which are named A (IA), B (IB), and O (i). Each person has two blood type alleles, i.e., one allele inherited from the mother and one from the father. The frequency of the O blood allele is very high in indigenous populations, and in Central and South American populations this allele may reach a frequency of 1 (100%). In consequence, the predominance of the O blood allele in Native American populations suggests that these populations descended from a founding population that had a high frequency of the O blood allele. A founder effect may even cause the fixation of one allele within a population, and this phenomenon is known to be associated with the loss of genetic variation.
Answer:
B. monitoring the transverse diffusion of human proteins within a mouse cell membrane
Explanation:
fluid mosaic model of membrane is considered to be as that structure of membrane in which protein layer is embedded between the two layers of lipids.
monitoring the transverse diffusion of human proteins within a mouse cell membrane did not verify the fluid mosaic model of membranes.
