Consider a cross between two individuals who are heterozygous for three traits (seed shape, color, and flower color), where one allele is dominant and the other allele is recessive. What is the probability that this cross will produce an offspring with ONLY recessive phenotypes for the three traits?
Homework Answers
1/64
- Let's consider following allele A, a, B, b,C and c.
- Probability that cross of AaBbCc × AaBbCc will result in offspring with recessive phenotype (aabbcc) is 1/64

You are interested in the inheritance of seed color (the Y-locus) and seed shape (the S-locus) in corn plants. At the seed color locus, the Y allele (yellow seeds) is dominant to the y-allele (white seeds). At the seed shape locus, the S allele (smooth seeds) is dominant to the s allele (rough seeds). You perform the following dihybrid cross between two corn plants, one of which has a yellow and smooth seeds (genotype: YySs), the other of which has...

A tomato plant heterozygous for stem color and fasciation (the dominant alleles linked on the same chromosome) is pollinated by a plant heterozygous for stem color and homozygous recessive for fasciation (that is nonfasciated). 29.

Drosophila females of wild-type appearance but heterozygous for three autosomal traits are mated to males that are homozygous recessive for the three traits. The three autosomal recessive traits are glassy eyes (g), coal-colored bodies (c), and striped thoraxes (t). The three dominant traits are red eyes (g+), gray bodies (c+) and solid thoraxes (t+) (remember, the wild-type allele has a + after it). You examine 1000 progeny of the above cross and they have the following phenotypic classes: 265 g+c+t+ 275 gct 120 g+ct...
