A pedigree analysis was performed on the family of a man with schizophrenia. Based on the known concordance statistics, would his MZ twin be at high risk for the disease? Would the twins risk decrease if he were raised in an environment different from that of his schizophrenic brother?

Assuming brown eyes (B) are dominant over blue eyes (b), determine the genotypes of all the following individuals. The blue-eyed son of two brown-eyed parents marries a brown-eyed woman whose mother was brown eyed and whose father was blue eyed. Their child is blue eyed.
Consider the pedigree below for a recessive autosomal trait caused by allele t. The dominant wild-type allele is represented by T. What is the genotype of individual 4 in generation II?
For the following traits, what information must you have in order to predict the phenotype of an offspring? A. Snail coiling direction B. Dwarfism due to a mutant Igf2 allele C. Leber hereditary optic neuropathy
The following pedigree describes the inheritance of Lesch-Nyhan syndrome, an x-linked recessive disease. Affected individuals are shaded. what is the probability, that the indicated child (IV.1) will be affected by Lesch-Nyhan syndrome? show solution
In humans, brown eyes (B) are dominant over blue. A brown eyed man marries a blue-eyed (b) woman and they have three children two of whom are brown-eyed and one of whom is blue-eyed. if blue is recessive, what must the woman’s genotype be?
In guinea pigs, the allele for short hair is dominant. If all the guinea pigs are born short haired what are the possible genotypes of the parents? (There are two possible combinations.) Show the answers with punnett square
Skin color in humans is determined by polygenic inheritance, which means the more dominant alleles there are, the darker the skin color will be. A medium-toned skinned woman (AaBb) has a child with another medium-toned skinned man (AaBb). What is the probability of them having a very dark-toned skinned child? (Hint: the genotype is homozygous dominant)
In flowers, the red color is codominant with the white color If a red flower is crossed with a white flower Predict the offspring genotypes and phenotypes .
Andalusian chickens may be either black, white, or gray. The gene for black is not dominant over the gene for white, nor is the gene for white dominant over the gene for black. When a black rooster is mated to a white hen, all gray chicks are produced. When gray chickens are mated, the chicks are black, gray, and white. Using a Punnett Square, demonstrate how feather color is inherited in Andalusian chickens. Is the inheritance of feather color in this problem an example of incomplete dominance? Why would it be impossible to establish a true breeding flock of gray Andalusian chickens? In guinea pigs, black coat color (B) is dominant to white (b), and a rough coat (R) is dominant to smooth (r). What are the expected genotypic and phenotypic results of the following crosses? BBRR x bbrr BBrr x bbRR Bbrr x bbRr BBRr x BbRr BbRr x BbRr A pure-breeding black, smooth guinea pig was mated to a pure-breeding white, rough female.They produced several litters,…
