The Hairless phenotype in Drosophila is caused by a recessive mutation in the H gene. Wild-type Drosophila have hairon all body segments. Two heterozygous Hh Drosophila are crossed: 25% of the offspring have normal hair on theirbodies and 25% have no hair at all. 50% of the offspring have less hair on their bodies than wild type, and the amountof hair they have varies.

In cows, there is a "splotchy" phenotype that is splotches of brown and white. A true-breeding white cow (homozygous recessive) is bred to a true-breeding brown cow (homozygous dominant). In the resulting offspring, 75% have spots of brown and white and 25% are brown. The phenotype described displays what kind of relationship(s) between alleles? Incomplete penetrance Incomplete penetrance Variable expressivity Variable expressivity Incomplete dominance Incomplete dominance Codominance
In certain lizards, scaly skin is dominant to smooth skin and speckled color is dominant to grey color. These traits are inherited according to traditional Mendelian genetics (no linkage). The total progeny for a breeding pair of lizards resulted in the offspring listed below. What are the genotypes of the male and female parents? 102 scaly skinned, speckled off spring 110 smooth skinned, speckled offspring 38 scaly skinned, grey offspring 32 smooth skinned, grey offspring
A cross was performed using Drosophila melanogaster involving a female known to be heterozygous for both ebony body and sepia eyes and a male known to be homozygous for both of these recessive traits. The following data was produced from the cross. Test these data to determine if they are significantly different from the expected phenotypic ratio. Remember to use the 5% level of significance Wild eye Wild body – 102, Wild eye Ebony body – 94, Sepia eye Wild body – 100, Sepia eye Ebony body – 93. Your answer should include the hypothesized cross in genotypes, the Chi-squared value, the critical value and whether you reject or do not reject.
The American Curl is a breed of cat that has curly ears. The allele for the curly ears is dominant (E). Suppose a cat with the heterozygous genotype is bred to a female cat with the homozygous recessive genotype. Fill out a Punnett Square and answer the following questions. What is the phenotypic ratio of this punnett square? If this cross produces six kittens, how many of them will have curly ears? ________
Bronze coloured turkey is controlled by a dominant allele, B. Red coloured turkey is homozygous for a recessive allele bb. Dominant gene N produce normal feather and recessive genotype produce ‘hairy’ feather nn. In a cross between homozygous bronzed coloured turkey with ‘hairy’ feather and homozygous red coloured turkey with normal feather. What are the ratios of F2 progeny with Bbnn genotypes? (I want to check if what i'm doing is correct)
A man has a roan bull and a white cow. His first 5 calves turned to be 2 roans and 3 white. Keeping in mind the fact that the roan is a color obtained when cattle are heterozygous for the gene for red and white, how frequently (probability of the phenotypes) would you expect such as a combination of offspring as that obtained in this case?
An allelic series determines coat color in rabbits: C (full color), c (chinchilla, gray color), c` (Himalayan, white with black extremities), and c (albino, all white). The C allele is dominant over all others, c is dominant over over c, and c is recessive to all other alleles. This dominance hierarchy can be summarized as C > c the table are crossed and produce the progeny shown. h Cc X c c Parents full color × albino Himalayan x albino full color x albino full color × Himalayan full color X full color Cross A B C D 50% full color, 25% Himalayan, 25% albino 75% full color, 25% albino E Match the parental genotypes to the letter corresponding to the appropriate cross listed in the table.

Phenotypic ratio: red : pink : white Solve the following genetic problems involving incomplete dominance. You must pick the right letter to represent the gene in the question. You must show your work using the Punnett square. 15. A rooster with grey feathers is mated with a hen of the same phenotype. Among their offspring 15 chicks are grey, 6 are black and 8 are white. a. What is the simplest explanation for the inheritance of these colors in chickens? b. What offspring would you expect from the mating of a grey rooster and a black hen?
In cattle, having spots (s) is recessive to being a solid color (S). If two cattle that are heterozygous for the condition mate ,What are the parental genotypes and phenotypes? What are the gametes produced by each parent? (Do a punnet square for the cross ). What proportion of their offspring will be solid in color ?
A pea plant showing two dominant phenotypes, tall plant (D) and purple flower color (W) is test-crossed with a plant showing both recessive phenotypes for dwarf plant (dd) and white color flower (ww). The results of the F1 offspring showed tall purple flower plants; tall white flower plants; dwarf purple flower plants; and dwarf white flower plants in approximately a 1:1:1:1 ratio. Based on these observations, what should be the genotype of the tested plant? DdWw DdWW ddWw DDWw DDWW
In Persian cats hair length can be short or long. Long hair is a recessive condition and this trait is an example of complete dominance. Assume that you cross two cats heterozygous for this trait and that 8 offspring are produced. What is the probability any 7 of the 8 could have short hair? Write the answer in the form 2!/1!1! * (3/4)^5. Do not write the actual value.
In horses, black color (B) dominates chestnut color (b). Trotting gait dominates pacing gait (t). A cross is made between a horse homozygous for both black color and pacing gait and a horse homozygous for both chestnut color and trotting gait. The probable genotype of the offspring resulting from such a cross is and the probable phenotype of the offspring resulting from such a cross is .
