Male Pattern Baldness Genes

Hard biology question? Genes?

page pattern baldness is caused by a recessive allele on chromosome X. Autosomal call Sickle cell anemia is caused by a form of red blood cells, the crescent while normal blood cells are round. If a person is heterozygous for disorder, with normal red blood cells and some red blood cells in crescent shape. Suppose a bald man with sickle cell disease have children with a woman that is homozygous normal for both disorders. What are the percentages of expected phenotypes of their children? What is recessive, red blood cells originally crescent-shaped red blood cell disorder or normal?

First we will assign letters to different genes. We call the S-cell anemia (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). As as information, parents ssbY (man is that wearing the baldness gene on their X chromosome, but has no second X chromosome that was so, then it is called hemizygous b – remember this word, that will impress your teacher). The mother is homozygous normal (wild type) for both, if it is SSBB. If you cross these people, you get: SB SB sY SSBB SsBY Therefore, the phenotypes are: SSBB (a girl who is [wild type normal] for both states, but it does do * some * sickle-shaped blood cells), but it is not bald, and SsBY (a child who is also the way * * to sickle cell, but not bald). BTW – blood cells Red Crescent in the form of the allele is recessive, if not completely, because some phenotype of a heterozygote.
