Sol. Male Guinea pig (Bb) is crossed with female Guinea pig (Bb) and observed that the number of the black Guinea pig and white Guinea pig a 3 to 1 ratio; that is, 3/4 were black and 1/4 white. So, the probability that the white Guinea pig will show 1/4 or 25% and the black Guinea pig will show 3/4 or 75%. Below the diagram:

Imagine that you just went to the pet store and bought two black guinea pigs that are known to be heterozygous (Bb). You also know that black fur (BB) is dominant over white fur (bb), and that a lethal recessive allele is located only one cM away from the recessive b allele. You decide to start raising your own guinea pigs, but after mating these animals several times, you discover they produce only black progeny. What is the probability of...

In guinea pigs black hair is dominant over white hair. You have several black guinea pigs and several white guinea pigs. You wish to pick out a pair of pure black (homozygous) pigs. Explain how you would determine whether a black guinea pig was homozygous or heterozygous.

A population of 464 guinea pigs are bred from a cross of heterozygote parents for two traits: fur color and texture. The dominant allele for fur is black (B), and the recessive allele for fur is white (b). For texture, rough fur is dominant (R), and smooth fur is recessive (r). How many individuals in the population have fur that is black and smooth? 16 261 0 29 Referring to the previous question, what is the phenotypic ratio of the...

Fur color in dogs can be black, brown or white. The B gene is responsible for fur color. Dogs that inherit a dominant B will have black fur. Dogs that inherit 2 recessive alleles, bb, will have brown color. There is a second gene that contributes to fur color in dogs: gene I. Individuals who inherit a dominant allele, I, at this location, will always have white color. Individuals who inherit the homozygous recessive condition, ii, will be able to...

6) A colorblind female, blood type A married 2 different men. One man (#1) had type AB blood and was colorblind. The other man (#2) had type B blood and normal color vision. Three offspring resulted from the marriages. If possible, determine the father of each of the following offspring. a) female, Type A blood, normal color vision b) male, Type AB blood, colorblind c) female, Type B blood, colorblind In tomatoes, red fruit color is dominant to yellow.

Question 25 2 pts In dragons, the dominant allele R causes solid tail color, and the recessive alleler results in white spots on a colored background. The black coat color allele Bis dominant to the brown allele b, but these genes can only be expressed if the animal has an mm genotype at a third gene locus. Animals that are M are yellow regardless of which allele from the Blocus is present. A mating between a solid yellow-tailed male dragon...

3. H > hch h h block chec cinnamon altin 3. In a certain species of cat, there are four alleles for fur color. The Hallele (black fur) is completely dominant over all other alleles. The chocolate allele h is recessive to the H allele but completely dominant to all other alleles. The cinnamon allele (his recessive to the Hand hch alleles but completely dominant to albino allele (h), which gives completely white fur...
