- List the possible genotypes of the parents if a cross resulted in a F1-generation consisting of 50% white colonies and 50% red colonies:In a true breeding parental cross for an Autosomal recessive disease trait, the expected proportion of males in the F2 generation that are unaffected is:A yellow female is crossed with a gray male. The F1 are intercrossed to produce the F2. Give the genotypes and phenotypes, along with the expected proportions, of the F1 and F2 progeny.
- In a parental cross of a ADHL disease trait, where the father is affected and the mother is unaffected, 50% of the offspring will have the disease phenotype and 50% will have the WT phenotype. In an F1 cross between an affected male and an affected female, the respective proportions of the disease phenotype and WT phenotype are:An individual whose genotype is AABbCc is crossed with an individual who is heterozygous for all three of these genes. List the Phenotype and Genotype. (Trihybrid and Polyhybrid)What will be the PR and GR of the following crosses? Give also their phenotypes. (Designate your own phenotype for each character) AaBb x aabb AAbb x AaBB AaBb x aaBB AABb x aabb
- an individual that is heterozygous for type A blood mates with an individual that has type o blood. what are the predicted genotypic and phenotypic ratios for this cross?Gene “A” and gene “B” are not linked. Each has two alleles. The A allele is dominant over the a allele and the B allele is dominant over the b allele. Answer the following questions about a dihybrid (two-trait) cross. A) List all of the possible gametes (eggs) that could be produced by an individual with the genotype: aabb B) List all of the possible gametes (sperm) that could be produced by an individual with the genotype: AaBB C) Fill out a Punnett square for the dihybrid cross cross between the two individuals listed above (aabb x AaBB). What percent of the offspring from this cross would have the dominant phenotype for both traits?Draw a Punnett square to indicate possible gamete types produced by each parent and the expected genotypes of their offspring for the cross: AaBb X aaBb.
