- 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?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.among a certain breed of dog, short hair is dominant to long hair and dark coat is dominant to white coat color assume that these two coat trades are caused by independently sick or getting in pairs for each of the cross was given below, write the most probable genotype for genotypes of more than one answer is possible for the parents first select define each symbol below.
- In a dihybrid cross of two bi-allelic Mendelian genes, A (two alleles – completely dominant A and recessive a), and B (two alleles – completely dominant B and recessive b), such that the parental generation comprises of pure-bred homozygotes (i.e. AABB with aabb), what are the expected genotype and phenotype ratios in the F1 and F2, if the F1 cross is (a) an intercross and if the F1 cross is (b) a testcrossMendel crossed two Pea plants for plant height and flower color Tall plant (T) is dominant to Short Plant (t). Purple Flower (P) is dominant to white flower (p). Using the following information perform the dihybrid cross using punnett squares that will predict all possible genotypes of the offspring and list the number and description of the phenotypes of the offspring. A. One plant homozygous dominant for plant height and flower color crossed with another plant homozygous recessive for plant height and heterozygous for flower color.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
- Explain the following features of the Mendelian traits and fill the Punnet Squares. a)The disappearance of recessive phenotype in the F1 generation. b)The genotype of an individual expressing dominant phenotype can be differentiated by the test cross.Assume that smooth seed coats are dominant over rough seed coat. If two pea plants that are both Heterozygous for seed coats are crossed, what do you expect in the offspring (the f1 generation)? Specifically, what genotypes, what phenotypes, and in what ratios? (Use S for the smooth seed coat and s for the rough seed coat.) (Again, it is helpful to write out all the possible genotypes and give the phenotype for each genotype before answering the specific question.) Be careful in writing capital S and lower case.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.

If we cross two pea plants that are heterozygous for color, what would be the expected phenotype ratio of the offspring? Do the Punnett square and write the phenotypic ratio in the space belowIn Japanese four o'clock plants red (R) color is incompletely dominant over white (r) flowers, and the heterogynous condition (Rr) results in plants with pink flowers.
