When working out genetics problems in this and succeeding chapters, alwaysassumethatmembersof the P1 generation are homozygous, unless the information or data you are given require you to do otherwise.
In Drosophila, gray body color is dominant over ebony body color, while long wings are dominant over vestigial wings. Work the following crosses through the F2 generation, and determine the genotypic and

- Autosomal Recessive Problem: What is probability of individual 2 III in pedigree 1 and individual 1 III in pedigree 2 to have an affect child?arrow_forwardSolving complex genetic problems with the rules of probability (3 traits) 1. Calculate the probability of getting an offspring of pea plant with the genotype, PpyyRr, when crossing PpYyRr and ppyyrr. Show your work. 2. States the phenotypes of the parents and offspring.arrow_forwardProblem Solving: In Drosophila, the gene that controls red eye color (dominant) versus white eye color is on the X chromosomes. What are the expected phenotypic results if a heterozygous female is crossed with a white-eyed male? In cats, S = short hair; s = long hair; XC = black coat; Xc = yellow coat; XCXc = tortoiseshell (calico) coat. If a long-haired yellow male is crossed with a tortoiseshell female homozygous for short hair, what are the expected phenotypic results?arrow_forward
- Analysis of Autosomal Recessive and Dominant Traits In the following pedigree, assume that the father of the proband is homozygous for a rare trait. What pattern of inheritance is consistent with this pedigree? In particular, explain the phenotype of the proband.arrow_forwardEngrailed, even-skipped, hunchback, and Antennapedia.To a Drosophila geneticist, what are they? How do theydiffer?arrow_forwardNeed help. Knowing that the Curly leaf (Cy) is a dominant gene on chromosome 6, as it is useful in tracking other genes using trisomics for chromosome 6. Assume a Cy Cy cy plant used as a pollen parent where disomic pollen does not function crossed to a Cy cy cy female where disomic eggs do function. A) What ratio would be predicted in the progeny of this cross? B) What if the reciprocal cross was made?arrow_forward
- Chi Squared Problems In the garden pea, yellow cotyledon color is dominant to green, and inflated pod shape is dominant to the constricted form. Considering both of these traits jointly in self-fertilized dihybrids, the progeny appeared in the following numbers: 193 green, inflated 184 yellow constricted 556 yellow, inflated 61 green, constricted Do these genes assort independently? Support your answer using Chi-square analysis. (SOLVE USING EXCEL)arrow_forwardgenetics question for Icke P. Jenny, like her mother, is heterozygous for both X-linked traits. Her father suffered from bothhypophosphatemia and muscular dystrophy. Jenny’s fiancé, Mark has a mother suffering from musculardystrophy despite having normal bone conditions. His father has been blessed with strong bones andmuscles but suffered from amelogenesis imperfecta. a. Give the complete genotypes of the following individuals: Jenny, Jenny's mother, Jenny's father, Mark, Mark's mother, Mark's father. b. Should Jenny and Mark eventually marry, what is the probability that they will have: a child with muscular dystrophy, a child with amelogenesis imperfecta, a son with hypophosphatemia, a daughter with muscular dystrophy, a child with the same genotype as Jenny, a child with the same genotype as Markarrow_forwardInstruction: Solve for the genetic problems. a.

PLEASEDEFINE YOUR SYMBOLS and show your work clearly.arrow_forwardPractice Pedigree Problem help. I am confused so please show. Label Phenotypes and genotypes as you go about the Pedigree (and whatever else might be required)! Thank you again for your help, these questions confuse me). Hair or fur length in cats is controlled by a single, autosomal gene; the short hair-allele is dominant to the allele for long hair. Hair color is produced by a different gene which is located on the X chromosome. One allele for this sex-linked gene produces yellow, while an alternate allele produces black fur color; individuals which are heterozygous for these alleles are calico or tortiseshell in color. a). If a long-haired, black male is mated with a calico female homozygous for short hair, what kind of kittens will be produced in the F1generation? Give both genotypes and phenotypes; express the genotypes both symbolically and in words.arrow_forwardHi, I'm having trouble with my study guide for my upcoming genetics exam. If someone could please help with work shown and an explanation it would help so much! Thank you!! 2a. The pedigree below represents inheritance of rare condition. What pattern of inheritance is most consistent with the data? Assign alleles to all individuals to support your answer. If an allele is unknown, assign it a ? symbol. NOTE: Individuals whose phenotype or genotype cannot be determined are assumed to be unaffected and homozygous, unless otherwise indicated. 2b. In addition to the alleles you’ve indicated, describe 2 overall features of the pedigree that make it consistent with your chosen form of inheritance. 2c. Based on your mode of inheritance, what is the probability that the child of couple IV-4 x IV-5 will be affected? Show your work. attached is the pedigreearrow_forward
