Male Pattern Baldness X Chromosome

Biology: I need some help with this genetic problem.?

page pattern baldness is caused by a recessive allele on chromosome X. Autosomal called sickle cell anemia is caused by the shape of red blood cells, the crescent, while normal blood cells are round. If a person is heterozygous for the disorder, they have normal red blood cells and some cells crescent-shaped red blood. Assume a bald man with sickle cell disease Sickle have children with a woman who is homozygous normal in both disorders. What are the percentages of expected phenotypes of their children? Which One is the recessive form red blood cell Crescent disorder that causes red blood cells than normal? mimi their help has been appreciated.

First we will assign letters to different genes. We call the Sickle Cell S (for normal blood allele WT) and S (for the gene for sickle cell disease). We call the gene for baldness B (for non-balding) and B (for male pattern baldness). Given that information, parents ssbY (man is that wearing the baldness gene on their X chromosome, but not have a second X chromosome, which was so, then is called hemizygous b – remember this word, that will impress your teacher). The mother is homozygous normal (wild type) for both, if SSBB. If you cross these people it is: SB SB SSBB sY SsBY therefore phenotypes are: SSBB (a girl who is wild-type [] normal of the two states, but makes some * cells in the form of blood to the sickle), but not bald, and SsBY (a guy who is * also * the form of blood cells in sickle, but not bald). BTW – Cells Blood Red Crescent in the form of the allele is recessive, but not completely, because there is a phenotype of a heterozygous genotype
