Calculate genotypes and phenotypes in monohybrid crosses of traits with non-Mendelian inheritance (codominance, incomplete dominance, lethal alleles, multiple alleles) A given trait is coded as an autosomal dominant characteristic with incomplete penetrance of about 40%. If heterozygote parents have kids, what would be the probability of one kid presenting this trait?

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?
Mendel performs a cross using a true-breeding pea plant with round, yellow seeds and a true- breeding pea plant with green, wrinkled seeds. What is the probability that offspring will have green, round seeds? Calculate the probability for the F1 and F2 generations.
Suppose a man is heterozygous for heterochromia, an autosomal dominant disorder which causes two different‑colored eyes in an individual, produced 25‑offspring with his normal‑eyed wife. Of their children, 16 were heterochromatic and 9 were‑normal. Calculate the chi‑square value for this observation.
Working with the definitions of penetrance and expressivity, analyze the following pedigree and assume that the father of the proband is homozygous for a rare trait. (Consider a rare trait here to be less than 1 in 30,000.) What pattern of inheritance other than autosomal recessive could explain this pedigree? In particular, explain the genotype and phenotype of the proband (arrow).
A cross between a black-furred male dog and a white-furred female dog could produce offspring with a black-and-white coat. This means that the color coat traits of the parents are codominant as both were expressed together. Show a cross between a Black-white furred dog and a homozygous white dog. Indicate the genotypes of both parents and the possible outcome in percentage.
Genetic cross with dependent assortment (linked traits). Repeat the previous problem but assume that the genes are located very close to each other on the same chromosome, and are therefore always linked (passed on together). Assume that in these individuals, each chromosome contains the dominant allele for one gene and the recessive allele for the other gene. Note: this is similar to the dependent assortment example in your notes, but the linkage is different. Construct a 2x2 Punnett square, and answer the questions below: GgBb x GgBb GB Gb gB gb GB GGBB GGBb GgBB GgBb Gb GGBb GGbb GgBb Ggbb gB GgBB GgBb ggBB ggBb gb GgBb Ggbb ggBb ggbb a) From your Punnett square, how many individuals are dihybrids? b) How many individuals are both homozygous recessive for coat color and heterozygous for eye color (ggBb)? c) Fill in the blanks to state the expected phenotypic ratio of the offspring:…
In rabbits, white coat color (CW) and black coat color (CB) are codominant, and both of these alleles are dominant over albino (c); heterozygotes (CWCB) are spotted. Predict the genotypes and phenotypes of the offspring from a heterozygous black-coated rabbit and a homozygous white-coated rabbit.
Mendelian Genetics Consider blue eyes in a man as recessive to brown eyes. Show the expected children of a marriage between a blue-eyed woman and brown-eyed man who had a blue-eyed mother. Determine the genotypic ratio (GR) and phenotypic ratio (PR) of the F1 using Punnett Square Method. Hint: Determine the genotypes of each individual first.
Give the genotypic frequencies expected under the Hardy–Weinberg law for (a) an autosomal locus with three alleles and (b) an X-linked locus with two alleles.
SELECT ALL THAT APPLIES. Which of the following statements are true regarding Mendel's observations of two factor crosses?
In guinea pigs, the black coat (B) is dominant over the white coat (b), and straight hair (H) is dominant over curly hair (h). Using a Punnett square, complete the cross between a heterozygous black, curly-haired individual and a homozygous straight-haired, white individual. State the parent genotypes and gametes, and the F1 phenotypes and genotypes.
In addition to the allelic pair determining pattern baldness in man (B,b), consider early baldness to be due to another autosomal allele (E) on a different pair of chromosomes and also dominant in males but recessive in females. The phenotype for ee may be late or nonbaldness depending on sex and the genotype for B, b alleles. Two doubly heterozygous persons marry. What is the phenotype of the male parent? What is the phenotype of the female parent? Give the phenotypic ratio expected among male children of couples such as this one. Show corresponding genotypes for each phenotype mentioned in your phenotypic ratio. Give the phenotypic ratio expected among female children of couples such as this one. Show corresponding genotypes for each phenotype mentioned in your phenotypic ratio.
