To determine:

The phenotype and genotype of the different coat colors expressed in the offsprings after mating yellow mice with a brown agouti mouse.

Introduction:

The genotype of an individual is defined as the genetic makeup and the placement of alleles at the chromosome. Phenotype, on the other hand, is defined as the visible characteristics of that individual.

A recessive maternal effect mutant in zebrafish, called ichabod, results in embryos lacking heads that are non-viable. You have been instructed to identify females that are homozygous for the ichabod mutant allele. At your disposal are a tank of wild-type fish (males and females), a tank of male and female parental fish that are all heterozygous for the ichabod mutant allele (ichabodl+), and a tank of F1 fish derived from a cross between a heterozygous male and heterozygous female (ichabodl+). Which of the following would be a way to identify females that are homozygous mutant, i.e. ichabodlichabod? Select all answers that would work. Cross F1 females to F1 males and observe their offspring. Crosses that produce headless offspring came from a homozygous female. a. Cross F1 males to females from the parental tank and observe their offspring. 25% of these crosses should produce headless offspring. b. Cross F1 females to F1 males to make the F2 generation. Cross F2 females to F2 males and…

Your internship with Dr. Nefario at Gru Industries is going well so far, but a recent mission to obtain a shrink ray requires a special kind of Minion. You identify that the ideal Minion phenotypes for this mission are two eyes, pale yellow, and short. From your previous work, you’ve found that:Two-eyed (D) is completely dominant over one-eyed (d)Yellow (Y) is incompletely dominant with white (y)Tall (T) is completely dominant over short (t) a. The only reproductive individuals you have at the moment (it was surprise mission!) are a true breeding two-eyed, yellow, short Minion and a one heterozygous for each trait. What genotypic ratios would you expect for this crossassuming that each locus is on a different chromosome? What total proportion would you expect to be the desired phenotype for the mission? b. The mission has since been delayed due to lack of financial support, so you’ve got some time. All the individuals from the F1 cross above are now reproductive. Which genotypes would…
