In chickens, the Leghorn variety has white feathers due to an autosomal dominant allele. Silkies have white feathers due to a recessive allele in a second (different) gene. If a true-breeding whiteLeghorn is crossed to a true-breeding white Silkie, what is theexpected phenotype of the F1 generation? If members of the F1generation are mated to each other, what is the expected phenotypic ratio of the F2 generation? Assume the chickens in the parental generation are homozygous for the white allele at one gene andhomozygous for the brown allele at the other gene. In subsequentgenerations, nonwhite birds will be brown.

A certain plant species has dominant red flower color (R) to the recessive white flower color (r). A pure breeding (homozygous) red-flowering plant is crossed with a pure breeding white-flowering plant. What are the possible outcomes for the F1 generation? (Show the Punnett square
In some sheep, horns are produced by an autosomal allele that is dominant in males and recessive in females. A horned female is crossed with a hornless male. One of the resulting F1 females is crossed with a hornless male. What proportion of the male and female progeny from this cross will have horns?
In Drosophila, sepia colored eyes are due to a recessive allele s and red eyes are due to a dominant allele S. If females with sepia eyes are crossed with homozygous males with red eyes, what phenotypic proportions will F1 y F2 respectively?
A heterozygous bald man marries a recessive nonbald woman. What is the phenotypic ratio of the F1?
In Elves, curled toes (T) is dominant to flat toes (t). If an Elf that is heterozygous were crossed with an Elf that is homozygous recessive, what possible offspring could there be in the F1 generation?
What is a reciprocal cross? Suppose that a gene is found as a wildtype (functional) allele and a recessive mutant (nonfunctional)allele. What would be the expected outcomes of reciprocal crossesif a true-breeding normal individual was crossed to a true-breedingindividual carrying the mutant allele? What would be the results ifthe gene is maternally inherited?
Cinnabar eye color is a sex-linked, recessive characteristic in fruit flies. If a female having cinnabar eyes is crossed with a wild-type male, what percentage of the F1 males will have cinnabar eyes?
Chickens, like all birds, have ZZ-ZW sex determination. The bar-feathered phenotype in chickens results from a Z-linked allele that is dominant over the allele for nonbar feathers. A barred female is crossed with a nonbarred male. The F1 from this cross are intercrossed to produce the F2. What will the phenotypes andtheir proportions be in the F1 and F2 progeny?
In cabbage butterflies, White wings are dominant to yellow wings. If a heterozygous white-winged butterfly is crossed with a yellow-winged butterfly, what are the possible genotypes and phenotypes of the offspring and the percent chance for each?
In currant moths, their Light color is sex-linked and recessive (d) to dark color (D). Question: What are the genotype and the phenotype of the parents if a certain cross yields ½ dark and ½ light colored females and all dark males? Take note that female moths are heterogametic.
In fruit flies, red eyes (R) are dominant over purple (r). Two red- eyed parents are crossed, producing an F1 generation of 76 red- eyed and 24 purple-eyed offspring. What is the approximate phenotypic ratio?
