Assuming no crossover takes place, how many copies of the short-hair allele (h) will be present in each cell from an F1 long-haired mouse at the following stages?
Oogenesis
The formation of the ovum (mature female gamete) from undifferentiated germ cells is called oogenesis. This process takes place in the ovaries (female gonads). Oogenesis consists of three stages known as the multiplication phase, growth phase, and maturation phase.
Cell Division
Cell division involves the formation of new daughter cells from the parent cells. It is a part of the cell cycle that takes place in both prokaryotic and eukaryotic organisms. Cell division is required for three main reasons:
The allele for long fur (H) is dominant over the allele for short (h) fur in mice. A mouse with long fur is crossed with a short-haired mouse, producing six F1 long-haired mice and seven F1 short-haired mice.
Assuming no crossover takes place, how many copies of the short-hair allele (h) will be present in each cell from an F1 long-haired mouse at the following stages?
