- 2. In a strain of chickens, there are birds with white, black, or blue feathers. In crosses between ten white hens and ten blue roosters, there are 100 offspring: 24 hens with blue feathers, 26 roosters with blue feathers, 23 hens with white feathers, 27 roosters with white feathers. When crossing blue hens and white roosters, there are 100 offspring: 25 hens with blue feathers, 25 roosters with blue feathers, 26 hens with white feathers, 24 roosters with white feathers. A. Using allele symbols, create a plausible explanation for these traits. Why is this trait not sex-linked? When crossing ten black roosters and ten white hens, you observe 100 offspring: 51 hens with blue feathers, 49 roosters with blue feathers. When crossing white roosters and black hens, you observe 100 offspring: 50 hens with blue feathers, 50 roosters with blue feathers B. Use allele symbols to create a plausible explanation for these traits. C. Using evidence of all crosses, what would you predict if you…Drosohpila Punnet Square of Crosses. I need results of F1 & F2 generation using Punnett Squares for: Make Punnet Squares of the following crosses •Drosophila Female wildtype cross Male White-eye •Drosophila Male wildtype cross Female White-eye •Drosophila Female Wild Type cross Male Scarlet Eye •Drosophila Male Wild Type cross Female Scarlet Eye Also, Which allele is heterozygous and which is homozygous, & which is dominant and which is recessive?A parental cross between homozygous wild-type red eyed females (X+ X+) were crossed with white eyed males (XwY). The F1 generation consisted of phenotypic X+Xw females and X+Y males. The F2 generation was produced by crossing the F1 generation and consisted of a ratio of 2 red eyed females (X+ X+ and X+ Xw) : 1 red eyed male (X+Y) : 1 white eyed male (XwY). Attached is a picture of a chi square analysis based on the results from the F2 generation. Please discus what conclusions can be made based on the data/findings. What inheritance pattern is this?
- 1) By convention, the recessive trait will determine the abbreviation used to track crosses if it is a mutant condition, since it stands out in contrast to the rest of the population. For example, if pea pods are typically green in color, a mutant condition might result in yellow pea pods; therefore, the lowercase letter ‘y’ would be used to depict the mutant state, yellow, while uppercase ‘Y’ would depict the wildtype (wt) condition, green. Remember that the mutant condition is not necessarily always recessive. 1 A) . If green is dominant wt (Y) and yellow is a recessive mutant condition (y), depict a Yy father mated with a YY mother in the Punnett. 1B) Considering the dominant allele, what colors are the parents in the cross above? Yy = _____________________ YY = _____________________ 1C) What colors are the offspring in the cross above? 1D) What is the phenotypic ratio of the offspring? 1E) What is the genotypic ratio of the offspring? (Remember, the genotypic ratio is based…Here are the progeny of this cross: (Note that the categories are not in any particular order.)Fly type # of prog.

- In a particular plant, two genes control leaf shape and color. Round leaves (R) are dominant to jagged leaves (r). Yellow fruits (Y) are dominant to white fruits (y). If you crossed a homozygous round, heterozygous yellow plant with a heterozygous round, white plant, what are the genotypes of the plants involved in this cross? Group of answer choices RrYY x RRyy RRYY x rryy RrYy x RrYy RRYy x RryyTOPIC: GENE INTERACTION AND EPISTASIS In pineapples, leaves may be spiny, spiny-tipped or piping.
