Mother's Blood type is A. The allele may be AA or AO. The chance of child gets type A from mother is 75% and Type O is 25%
Father's Blood type is AB. The allele is AB. The chance of child gets type A from father is 50% and type B is 50%.
so
Add the results for AA and A0 together.
Note: The 50% of children may males or females

1. For each of the following blood types, list the possible genotypes: Phenotype Possible Genotypes A B AB O 2. Dr. Paul is blood type O. His father was blood type A and his mother was blood type B. What were the genotypes of his parents? What are the possible blood types and phenotypic ratios expected for a cross involving these parental genotypes? 3. In the ABO blood system in human beings, alleles A and B are codominant and both are...

X-linked Recessive Traits Review X-linked traits in your textbook. 1 In cars, the Ballele produces black fur & b produces orange fur. This gene is X-linked (X & X". Both colors are expressed in heterozygotes calico). If alcat has 2 calico kittens, 1 male black kitten, and I female orange kitten, what is the ty p henotype of the father cat? (Hint: Work backwards & use a Punnett square Remember that not every...
Hemophilia is an X linked recessive condition in humans (Xh). Blood type (AB) is determined utilizing multiple alleles of I, two of which are codominant. A widow's peak is determined by a single dominant allele (W), while the recessive phenotype is a straight hairline. The ability to taste PTC is determined by a single dominant allele (T). while the recessive phenotype is a non-taster. Eugene is a non-taster male who does not have hemophilia. He has AB blood and a...

Miniature wings (min) is an X-linked recessive mutation in flies. If a min-winged female is crossed to a wild-type male, what proportion of the Fį will have min wings? A. 0% B. 25% C. 50% D. 100% Vladimir is a carrier for diastrophic dysplasia (Dd), an autosomal recessive disorder and has achondroplasia, which is an autosomal dominant trait (Aa). Sophie is also a carrier for diastrophic dysplasia and also...
Can someone draw the punnet square and help explain this
question
6. In Drosophila, the recessive allele for forked bristles is sex-linked, and the recessive allele for purple eyes is autosomal. The wild-type alleles are for straight bristles and red eyes, respectively. A female heterozygous for both pairs of alleles is mated with a male with forked bristles and purple eyes. What percentage of the daughters will have forked bristles and purple eyes? 100% $75% 50% €25% E0%
I did 1-5 but confused on the rest
LAB EXERCISE 4.1 continued Name 6 Remember that the ability to taste PTC is dominant to the inability. Two normally pigmented taster parents have an albino, taster son and a non-taster daughter with normal pigmentation. Using A and Tand a and t for the dominant and recessive alleles, respectively, create a Punnett square for two traits, as shown on pages 71-73 in the section "Transmission of Autosomal Traits: Two at a Time."...
1. People wit h the sex-linked genetic disease, hemophilia, suffer from excessive bleeding because their blood will not clot. Tom, Mary, and their 4 daughters do not exhibit symptoms of hemophilia. However, their son exhibits symptoms of hemophilia because: A) Tom is heterozygous B) Tom is homozygous C Mary is homozygous D) Mary is heterozygous E All of the above are equally likely What is the risk of having a child affected by disease with an autosomal recessive inheritance both...
