5) Scale color in dragons is determined by two genes. The W gene is epistatic to the G gene. The W allele is dominant and allows the production of pigment, while w is recessive and blocks pigment formation, resulting in white dragons. When pigment formation is possible, the dominant G allele results in green dragon scales, while the recessive g allele results in black dragon scales. The pigment formation pathway is shown below. (3 points) W (Enzyme 1) G (Enzyme 2) White precursor Black intermediate pigment Green pigment a. What color scales would you expect in each of the following dragons? WwGg Wwgg wwGG wwgg b. If you cross two dragons with WwGg genotype, what is the expected phenotypic ratios of the progeny?

Pigment of chicken feathers is regulated by two genes, the gene for feather pigment C, and a gene that inhibits pigment production, I. A mother chicken, who is heterozygous for gene c, and heterozygous for gene I, is crossed with a father chicken, who is homozygous recessive for the pigment gene, and heterozygous for gene I. Inhibition is dominant to uninhibited, pigmented feathers are dominant to unpigmented feathers. The inhibitor gene (I) will prevent expression of pigmented chicken feathers. Here is a DihybridCrossReview(8).pdf Download DihybridCrossReview(8).pdfreviewing the FOIL method for determining gametes and performing a dihybrid cross if you need a refresher.

Cats are hairless when homozygous recessive (hh) for the Hairless gene. Cats have straight hair when recessive for the curly gene (cc). The H gene determines whether hair can be produced, and the C gene determines whether the hair is curly. These genes work in an epistatic pathway, with H/h first, then C/c. You cross a straight-haired cat to a hairless cat with genotype CChh, and find that all of the F1 kittens have curly hair.
As seen in the photo, Labradors come in three colors-- black, brown and yellow. What is the genetic basis for these different coat colors? One gene produces melanin, a pigment which is deposited in the dog's fur and makes the color dark. With this gene, allele B (black) is dominant to allele b. Only in the case of a recessive homozygote (bb) will the dog's phenotype be brown. The regulatory gene is separate from the melanin gene but it acts as a switch, either turning the melanin gene on or turning it off. Allele E is dominant and allows for the melanin to be deposited in the dog's fur ("on" switch), but if the switch gene is a recessive homozygote, the melanin is blocked ("off" switch) and a yellow dog is the result! Review the information on Labrador retrievers above. What are the phenotypic ratios of the F1 generation offspring of two dihybrids? Make sure to match the numbers with coat colors (e.g, which number in the ration goes with which color). Use a Punnett square to…

At least two pairs of genes control eye color. Both pairs influence the production of the pigment, melanin, but act independently. One pair of alleles is B (Brown color; dominant) and b (blue color); the other pair is A (pigment production; dominant) and a (no pigment production; albino). The gene pair aais epistatic to (masks) B and b and produces the nonpigmented eyes of the albino. What is the typeof gene interaction that exists between the two gene pairs? Give the genotypes and phenotypes of the possible offspring of the mating bbAa x Bbaa andi ndicate the parental phenotypes. (any method)

Two hedgehog parents are heterozygous at the spiny locus, each with genotype Ss. This locus affects the length of the individuals’ spines, which ranges from 1 cm in SS homozygotes to 3 cm in ss homozygotes.Inheritance of spine length in this family is entirely due to the spiny locus and it exhibits additivity. Remember that development of spines depends on thousands of genes, but we’re only considering this one gene because it’s the one that varies in a way that affects spine length in this family. a) List all of the phenotypes we could observe among offspring of these Ss heterozygote parents. b) What’s the probability that an offspring of these heterozygous parents is an SS homozygote? c) If the parents have exactly two offspring, what is the probability that the two hedgehog kids have no alleles in common? In other words, what’s the probability that one kid is SS and the other ss?
20. 20.Which among the following statements is INCORRECT? A. Codominance is evident when a cross between organisms with two different phenotypes produces offspring that exhibits both parental traits because the alleles for each trait are neither completely dominant nor recessive B. Incomplete dominance is evident when a cross between a white carnation and a red carnation results in a pink carnation flower. C. Law of dominance state that if the alleles of a specific gene differ from each other, only one phenotype will be expressed while the other is masked D. The inheritance of one trait does not affect the inheritance of the other trait especially if the allele of the other trait is located in a different chromosome
Piebald spotting is a condition found in humans in which there are patches of skin that lack pigmentation. The condition results from the inability of pigment-producing cells to migrate properly during development. Two adults with piebald spotting have one child who has this trait and a second child with normal skin pigmentation. a. Is the piebald spotting trait dominant or recessive? What information led you to this answer?
