- The pedigree shows inheritance of an autosomal recessive disease in an extended family. Assume unrelated individuals marrying into the family do not carry the disease, unless there is reason to believe otherwise. What is the chance that IV-3 and IV-4 will have a child with the disease?

(Check all that true.) M Two alleles segregate during meiosis, ending up in different gametes. Each pea plant has 2 alleles for every gene, but only contributes one in each gamete. The recombination of alleles in a zygote is completely random. The Law of Independeht Assortment was determined by following three traits in pea plants, TMendle was able to determine his Law of Segregation by following ane trait in pea plants. Every offspring inherits only 1 allele from each parent.TTGG ttgg F1 TG tg F2 TtGg Which types of genotypes are represented in F1 and F2 in the above figure, respectively? heterozygous and heterozygous heterozygous and homozygous homozygous and heterozygous homozygous and homozygous
- Rh factor is a protein that can be found on the surface of red blood cells. If your phenotype is Rh+ you have this protein on your red blood cells. If your phenotype is Rh-, then you do not have this protein on your red blood cells. Rh factor follows simple Mendelian genetics, meaning if you are Rh positive you can have the genotype Rh+Rh+ or Rh+Rh-. If Ruby's genotype is IBiRh-Rh-, and Sam's genotype is IAIARh+Rh-, what is the probability that their baby will be type AB+?Hemophilia A is caused by a recessive X-linked allele that encodes a defective form of a clotting protein. If a affected father and a mother who is known to not be a carrier have children, what percentage of female offspring will have hemophilia?As a research project, a group of students created a pedigree showing the incidence of sickle cell anemia in a family over three generations. Generation I 1 2 Generation II 4 7 Generation III 8 9 10 11 Unaffected male Unaffected female Affected male Affected female

What fraction of their children are likely to suffer from hemophilia. what fraction are likely to be carriers.A man with type AB blood and a woman with type O blood could have children with which blood type(s)? Type AB only Type O only Туре А & Туpe B О Туре А, Туре В, & Туре OA graduating nursing student wanted to know the different blood groups and how they can be inherited. She understood that multiple allele is the inheritance pattern for ABO blood type while complete dominance for Rh factor (Rh + is dominant over Rh -). Now she wanted to know what the probable blood types from the 3 systems on her future children are. Consider the nursing student has AB, Rh negative and her current husband has O, heterozygous Rh positive. 1. What is the probability of having a child with a blood type of type O?
