Answer: A geneticist studies a series of families in which both parents are normal and at least one child has albinism. The geneticist reasons that both parents in these families must be heterozygotes and that albinism should appear in of the children of these families. To his surprise, the geneticist finds that the frequency of albinism among me children of these families is considerably greater "Than . Can you think of an explanation for the Thigher-than-expected frequency of albinism among These families?

Answer:
Wegener presented a number of evidence to prove his plate tectonic theory, such as :
- The matching of rocks on each side of the Atlantic Ocean like a puzzle.
- His knowledge hat organisms such as freshwater reptiles were found in almost all continents
- He also identified organisms that live in different continents, and could not possibly cross over to the other continents due to water bodies (oceans) separating the continents.
Wegener's plate tectonic theory caused doubts to other scientists, because of the way he presented his evidence. Other scientists considered his mechanisms unrealistic
Explanation:
Mitosis is the process of cell division, where one parent cell divides to produce two genetically identical daughter cells. This process is vital in growth and tissue repair.
The reason that tissue from the fetal stage is helpful in studying mitosis is because mitosis is continuously and rapidly occurring in this phase of life in humans. The high rate of mitosis is due to the need for the fetus to grow rapidly and develop the necessary parts for it to be born.
