Answer: The cross will produce 4 offsprings with the following genotypes:
XhXh, XhX, XhY and XY.
Explanation: Hemophilia is an X-linked disease. A woman who carries the hemophilia gene but doesn't not express it is heterozygous, therefore she has a genotype of XhX, and a man who has hemophilia has a genotype of XhY. A cross between them will produce one female and one male who are hemophilic (XhXh and XhY), one female who is a carrier (XhX) and one normal male.
See the punnett square attached for the cross
Mitosis (also known as cellular division) is just copying of cells. So the answer would be 18.If the question were about meiosis (sexual division), then the answer would be 9, because that would make 4 daughter cells, each encompassing half the original number of chromosomes (18).
