Shared problems with a yellow plant. All of the offspring are yellow. When you crus this be? Can you hypothesize that either elow offspring, they produce two purple offspring, Wha type of inherias purple or yellow is dominant? (1 pt) e could 2. Coat color in mice is very complicated, but we'll use a hopocdhetical simpke eu monik out whether question. You cross a yellow mouse with a black mouse. Explain how you mple for this the trait was x-linked or autosomal by louoking at he ofsgrinversus an you could work out whether from future crosses. In other words. think about what possible crosses would give different results for an X-linked trait versus an autosomal trait. (1 pt.) 3. In cats, there is a gene that has an allele for yellow fur and an allele for black fur. The heterozygous "tortoise-shell" condition is exhibited only by the femake, and is a result of mosaic expression. This gene is found on the X chromosome. (I pt.) What kinds of offspring would you expect to result from the cross of a tortoiseshell female cat with a yellow male cat? Please show your work. Genotypes: Phenotypes: 4. In incomplete dominance, the heterozygote shows an intermediate phenotype. This is found in four o'clock flowers. R is the red allele and Rg is the white allele. (1 pts.) A. If you cross a pink flower with a white flower, what is the probability that an individual offspring will be red? hite? B. What is the probability that one offspring will be red or w

Explanation / Answer

1. It is the phenomenon of independent assortment .since in F1 generation all the offspring produced were yellow, so we can say that yellow may be a dominant trait.

B) it is 75% that progeny can be red and white
