An expecting mother underwent a fetal blood test to determine if her unborn child has a genetic disorder. The results from the test indicated that the fetus has 3 chromosomes 21. No other individual within this family has this genetic anomality. Explain how this happened

Hemophilia, disease in which the blood lacks a clotting factor, is caused by an X linked recessive gene. Joe doe not have hemophilia and Lucille is heterozygous for the condition.  What is the chance that their MALE child will have hemophilia? (Note: you are calculating the probability for their MALE children only, in other words if they have 1 male child, what is the probability that he will be born with the disease?)     0%     1/4 or 25%     2/4 or 50%     3/4 or 75%     4/4 or 100%

Explain this to me…..

One of your patients, a six-year-old girl who suffers from Sickle cell anemia, an inherited blood disorder in which red blood cells are abnormally shaped and fragile, leading to a short supply of red blood cells.  These abnormal cells can also get stuck in small vessels, which prevent blood flow, leading to fatigue, pain and other severe complications. Sickle cell anemia is an autosomal recessive disorder. Neither of your patient's parents has sickle cell anemia. What is the most likely genotype of her parents? (The normal beta-globin allele is abbreviated as B, and the abnormal allele as b.) one is B and one is b   one is BB and one is bb   both are Bb   both are bb   both are BB

Can you please not type the answer can you write it on a paper

The questions below all refer to the following pedigree. The locus for allele D/d determines how cilia function within the body. Mutations at this allele cause abnormal ciliary function, resulting in a clinical disorder characterized by frequent respiratory infections (including in the ears, sinuses, and lungs), as well as infertility. In the pedigree, black circles/squares represent individuals affected by the disorder. White circles/squares represent unaffected individuals. Remember, if a trait is rare in a population (such as this one), we assume individuals marrying into the family are NOT carriers unless the information provided indicates otherwise. A1 A2 II B1 B2 B3 B4. B5 B6_ II C1. C2 C3. C4. C5 IV D1. D2, D4 . D5 Individuals C2 and C3 are considering having additional children. However, having already had a child with this disorder, they visit a genetic counselor to determine what the probability is that their future child would have the disorder. If C2 and C3 have another…
