The progeny of a mating between two pure-breeding plants, one with the dominant characteristic caused by S, and the other with the recessive characteristic caused by s, will yield progeny with a mix of dominant and recessive characteristics. An individual that is Ss is pure-breeding for the S gene. A mating between SS and Ss individuals will result in all pure-breeding progeny. An individual that is SS is pure-breeding for the S gene.

Heterozygous Cc chickens express a condition called creeper, in which the leg and wing bones are shorter than normal (cc). The dominant C allele is lethal when homozygous. Skin color is determined by the alleles W and w. W_ chickens have white skin and ww chickens have yellow skin. In a mating between 2 chickens heterozygous for both of these genes: 1) What phenotypes will be observed in the progeny? 2) What fraction of the offspring will have each phenotype? Assign alleles. List possible phentoypes. Make gametes, draw Punnett square, and list fractions of genotypes and/or phenotypes of offspring,

If two alleles show incomplete dominance O the genotypes of homozygous dominant and heterozygous individuals are difficult to determine. O the genotype of heterozygous individuals can be directly determined from phenotype. O they are inherited at a 3:1 ratio. O they cannot be assessed using the Hardy-Weinberg equation, as there is no recessive allele. O they will be favored during recombination over the recessive allele.
With regard to heterosis, is each of the following statements consistent with the dominance hypothesis, the overdominance hypothesis, or both? A. Strains that have been highly inbred have become monomorphicfor one or more recessive alleles that are somewhat detrimentalto the organism. B. Hybrid vigor occurs because highly inbred strains are monomorphicfor many genes, whereas hybrids are more likely to beheterozygous for those same genes.C. If a gene exists in two alleles, hybrids are more vigorousbecause heterozygosity for the gene is more beneficial thanhomozygosity of either allele.
In a certain breed of dog, the dominant, B, is required for black fur; it’s recessive, b, produces brown fur. However, the dominant, I is the epistatic to the color locus and can inhibit pigment formation. The recessive allele, i, on the other hand, permits pigment deposition in the fur. What would be the phenotypes of the following sets of parents and what would be the results of the mating BBii x bbIi 1/4 black, 1/4 brown, 1/2 no color 1/2 black, 1/2 brown 1/2 black, 1/2 no color 1/3 black, 1/3 no color, 1/3 brown

A sex-influenced trait is dominant in males of a certain speciesof animal and causes bushy tails. The same trait is recessive infemales. Fur color is not sex-influenced.Yellow fur is dominantto white fur. A true-breeding female with a bushy tail and yellowfur was crossed to a white male without a bushy tail (i.e., a normaltail). The F1 females were then crossed to white males withoutbushy tails. The following results were obtained: A. Conduct a chi square test to determine if these two genes arelinked.B. If the genes are linked, calculate the map distance betweenthem. Explain which data you used in your calculation.
All of the following statements aboutinheritance are true, except one. Which one of the following statements is INCORRECT ? O All genes have two alleles: one dominant and one recessive. Some phenotypes arise from the interaction of more than one gene. O Incomplete dominance is when heterozygotes express a phenotype that appears to be a blend between the phenotypes of homozygotes. O Even If you know the genotypes of both parents, you cannot always know with certainty the genotype their child will have.
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?

In rabbits, the color of body fat is controlled by a single genewith two alleles, designated Y and y. The outcome of this traitis affected by the diet of the rabbit. When raised on a standardvegetarian diet, the dominant Y allele confers white body fat,and the y allele confers yellow body fat. However, when raisedon a xanthophyll-free diet, a homozygote yy rabbit has whitebody fat. If a heterozygous rabbit is crossed to a rabbit withyellow body fat, what are the proportions of offspring withwhite and yellow body fat when raised on a standard vegetariandiet? How do the proportions change if the offspring are raisedon a xanthophyll-free diet?
