What are the possible genotypes and phenotypes (include probabilities) of offspring from a cross between a female that is homozygous normal for the X- linked recessive allele that produces Wiskott-Aldrich syndrome (WAS) and a

Sickle cell anemia is inherited as an autosomal recessive condition. It also exhibits incomplete dominance in that the heterozygous genotype displays a mild form of the disease known as sickle cell trait while individuals with the homozygous recessive genotype have a severe form of SCA. A man who has severe sickle cell anemia marries a woman who suffers from a mild trait. What is the probabilitu they will have a child with severe SCA?What is the probability they will have a child with mild SCA? What is the probability they will have a normal child? Show ALL work using punnett squares.

I will be adding two questions here because I asked two of the same questions twice by accident earlier.  A man and a woman do not have hemophilioa, but the womans father did. (Hemophilia is X-linked recessive). a) What is the probability that they will have a child with hemophilia? b) Is it possible for any of their daughters to be affected? Explain. A cross between a horse homozygous for red hair and a horse homozygous for white hair results in offspring with the coat colour called roan. When you look at the fur of the roan offspring you see both red and white hairs. What type of inheritance best explains this?  a) blending inheritance b)codominance c)incomplete codominance d)multiple alleles

An X-linked dominant allele controls the androgen receptor mutation that is responsible for male pattern baldness (MPB). A father who shows MPB has two children, with a mother who is a heterozygote carrier for the mutation. What is the probability that neither child will be affected by MPB? а. О.25 b. О.5 с. 0.03 d. 0.12 e. 0.0625

Duchenne muscular dystrophy is a recessive disorder caused by a rare,loss-of-function allele that is located on the X chromosome in humans. Anunaffected woman (i.e., without disease symptoms) who is heterozygousfor the X-linked allele causing Duchenne muscular dystrophy has childrenwith a man with a functional (non-disease-causing) allele. What is theprobability that this couple will have an unaffected son?

In humans, red-green color-blindness is a recessive X-linked trait. A man with red-green color- blindness marries a normal-vision woman whose father was color-blind. As the genetic counselor, construct a Punnett square to determine the genotypic and phenotypic possibilities of their children. orange is due to heteroz means In human, assume that albinism is an autosomal recessive characteristic while hemophilia is X-linked recessive. An albino nonhemophiliac man has children with a normally-pigmented nonhemophiliac woman whose father was a hemophiliac and whose mother was albino. Calculate the phenotypes of the children they could produce.

Imagine a cross between a man and a woman having the following genotypes:    Genotype of the Husband                                                                  Genotype of the Wife                                  Aa bb Dd Gg Hh RR Tt                  X                  Aa Bb Dd gg Hh Rr Tt Assuming that the dominant allele in each gene pair exhibits complete dominance over the recessive allele, what is the probability that this couple would have a daughter who exhibits the recessive phenotype with respect to all seven of the gene pairs?

Anhidrotic ectodermal dysplasia is an X-linked recessive disorder in humans characterized by small teeth, no sweat glands, and sparse body hair. This trait is usually seen in men, but women who are heterozygous carriers of the trait often have irregular patches of skin with few or no sweat glands (see the illustration below). a. Explain why women who are heterozygous carriers of a recessive gene for anhidrotic ectodermal dysplasia have irregular patches of skin lacking sweat glands. b. Why does the distribution of the patches of skin lacking sweat glands differ among the females depicted in the illustration, even between the identical twins?

Determine what is the most likely mode of inheritance of this disease (whether it is inherited as the result of an X-linked dominant or X-linked recessive trait). Use "A" for the allele associated with the dominant phenotype, and lowercase "a"" for the allele associated with the recessive phenotype. Write the most probable genotype for each individual based on the mode of inheritance you have determined. Show how all the partners are crossed and the expected offspring produced (You may use Punnett Square). OT I OT do II

When expressing X-linked recessive gene notation, how should the notation be written. Should I use XaXa for the recesive and Xa+Xa for heterozygotes? Is there a better/more correct way to write this?
