3. In celery, the leaves can be curly or flat. Curly is dominant and flat is recessive. The other trait is spots on the leaves. Dark green spots are dominant over white spots. Cross a celery plant that is heterozygous for both traits with a plant that has curly leaves (one of its parents had flat leaves) and white spots.
A. Parent genotypes?
B. Fill in Punnett square.
C. What is the ratio of genotypes?
D. What is the ratio of phenotypes?

2. The lubber grasshopper is a very large grasshopper, and is black with red and yellow stripes. Assume that red stripes are expressed from the homozygous RR genotype, yellow stripes from the homozygous rr genotype, and both from the heterozygous genotype. A.

Evaluating your phenotypes and genotypes and testing a genetic hypothesis in corn There are two activities in this write up. In the first, you will evaluate your phenotypes and genotypes and relate them to parental phenotypes and genotypes. In the second, you will test a hypothesis using a monohybrid cross in corn and carry out a Chi-squared analysis. For the write up, please copy and paste the remaining part of the Lab document into a new document, then fill in...

Let's say that in chipmunks, the allele for a black tail stripe (B) is dominant to the allele for a white tail stripe (b), and that the allele for patches of fur on an ear ("ear tufts") is determined by a recessive allele (e), with plain ears resulting from a dominant allele (E). A chipmunk that is homozygous recessive for the tail trait and heterozygous for ear morphology mates with a chipmunk that is heterozygous for both tail and ear...

1.My wife has black color eyes, the dominant trait. All of her family and relatives have dark eyes too. I have light color eyes (blue), the recessive trait. We are hoping for a blue-eyed baby. What is the probability we will have a baby with blue eyes? What is the probability we will have a baby with dark eyes? 2. In humans, tongue rolling is a dominant trait, those with the recessive condition cannot roll their tongues. Bob can roll...
