Fur color in Labrador Retrievers is a Polygenic trait with Epistasis. There are two genes and two alleles for each gene: Gene 1: Gene 2: B = Black coat (dominant) T = Add pigment to fur (Dominant) b = Brown coat (recessive) t = No pigment (Recessive) (Yellow) Mate two retrievers with these genotypes: Male BbTt x Female bbTt. From the cross above, what is the probability of having a Brown Labrador Retriever puppy?

In the tomato, three genes are linked on the same chromosome. Tall is dominant to dwarf, fruit skin that is smooth is dominant to skin that is peachy, and fruit with a normal tomato shape is dominant to oblate shape. A plant that is true-breeding for dominant traits was crossed to a dwarf plant with peachy, oblate fruit. The F1 plants were then test crossed to dwarf plants with peachy, oblate fruit. The following results are obtained. 200 tall, smooth,...

a) In radishes, the plants can be tall (allele T) or dwarf (allele t). Tall is dominant. Root color can be red (allele RR), white (allele RW), or pink (heterozygote). A radish that is true-breeding for both red roots and tallness (RRRR TT) is crossed with a radish that is true-breeding for both white roots and being dwarf (RWRW tt). Write the genotype and phenotype for the F1 generation. b) Assume the two genes for plant height and root color are...

Given the following data, what is the recombination frequency between these genes for squash color (red, yellow) and squash shape (log, oval)? What is the distance between the two genes in centiMorgans (or map units)? For full credit, you must show your work, i.e. how you made your calculations. (4 points) 3. Answer this question based on the following information. For full credit, you must clearly show how or explain how you came to this answer. Fur color in Labrador...

1.
There is a gene for height in a species of pea plant that we will
call "T gene". We would denote the dominant allele for this gene as
_____ and the recessive allele as _____. A homozygous dominant
individual's genotype would be _____, a homozygous recessive
individual's genotype would be _____, and a heterozygous
individual's genotype would be _____.
2. If this gene for height in pea plants shows complete
dominance (where the dominant allele...

Let's use this equation to solve the following problem: In pea plants, the allele for tall plants (T) is dominant to the allele for dwarf plants (1). If a population of 100 plants has 36 dwarf plants, what is the frequency of each allele? Here is a step-by-step guide: 1. Let p = frequency of the dominant allele (R), and q = frequency of the recessive allele (1). 2.92 = frequency of the homozygous recessive = 36%, or 0.36. Since...

1.Certain characteristics, like coat color in many animals, is influenced by multiple genes. The phenomenon during which the presence of a homozygous recessive genotype at one locus "overrides" or masks the phenotype that would otherwise be produced by the alleles at another locus (regardless of whether they are dominant or recessive) is called: pleiotropy codominance Punnett effect recessive Epistasis 2. Which of the following would be considered a pleiotropic gene? A gene that-along with several others-influences a single phenotype, such...
