In cats, short fur is dominant over long fur. Suppose a long furred male is bred to a short furred female who had a father with long fur. What proportion would you expect to have long fur?
Let "S" be dominant trait for short fur and "s" be the recessive trait in cats.
Male is always homozygous (ss) in order to expressive recessive trait, long fur. Female is heterozygous, because her father is long furred recessive.
. If the female is heterozygous (Ss), the chance of forming long furred offsprings are of 50%.
The cross between homozygous (ss) male cat and heterozygous female cat (Ss) are illustrated in below Punnett square.

From this it is clear that, out of the 4 possible outcomes or offsprings, 2 will result in short hair, and 2 in long hair cats. So, the chance of getting long furred cats are 50%. And the proportion of forming long furred cats are 1/2.
In cats, short fur is dominant over long fur. Suppose a long furred male is bred...
In guinea pigs, the allele for short hair is dominant over long hair. If a heterozygous short hair guinea pig is crossed with another heterozygous short hair guinea pig, what is the probability of an offspring having long hair? In pea plants purple flower allele is dominant to white flower alleles. If a homozygous purple flower plant is crossed with a white flower plant, what percent of their offspring would you expect to be purple? Straight fur (S) is dominant...
17. In cats, yellow fur is dominant to black fur. The heterozygous tortoise-shell" or "calico" condition is exhibited only by the female. The fur trait is sex-linked. What offspring (genotypes, phenotypes and frequencies) would you expect from the cross of a black male with a yellow female? What kinds of offspring would you expect to result from the cross of a black male with a tortoise-shell female? How about the cross of two tortoise-shell animals?! dong
In mice, black fur (B) is dominant over brown fur (b). Breeding a brown mouse and a homozygous black mouse produces all black offspring. a. What is the genotype of the gametes produced by the brown-furred parent? ________________________________________________________ b. What is the genotype of the brown-furred parent? ________________________________________________________ c. What is the genotype of the black furred parent? ________________________________________________________ d. What is the genotype of the black-furred offspring? By convention, P stands for the parental generation. The offspring are called...

4. In cats, black color is dominant to a special, temperature-sensitive albino gene which produces cats with dark legs, faces and tails (Siamese cats). A short haired (dominant) Siamese colored female is bred to a long-haired recessive) black male. They have eight kittens: 2 black, short-haired; 2 black, long-haired; 2 Siamese, short-haired; and 2 Siamese, long-haired. What were the genotypes of the two parents?
how
would you test if the genes for body color (B dominant over b) and
wing shape (V dominant over v) were linked (close to each other on
the same chromosome)?
In tortoiseshell cats, a gene on X chromosome determines fur color. Explain why female but not male cats have mosaic fur, containing patches of orange and black color.
You must record all crosses and results on the log sheets provided in this lab. Your completed log sheets must be attached to your final report as an Appendix. PART IV: POST-LAB. These following exercises must be completed in your labreport: 1. Length of fur is also genetically determined. The allele L produces long fur and its corresponding allele, I produces short fur. Long fur is dominant to short. a) You mate 2 hamsters. Both heterozygous for brown long fur....

1. In corn, purple kernels are dominant to yellow kernels, and starchy kernels are dominant to sweet kernels. If the genotypic verent crosed with a yellow, sweet parent? What would be the phenotypic ratio of the Fa complete dominance is the pattern of inheritance, what would be and phenotypic ratios for the offspring of a true breeding purple, starchy generation? 2. In guinea pigs, a cross between black furred and brown furred parents gives offspring with 100% black...
In mice, the allele for black fur (B) is dominant over the allele for cream fur (b), and the allele for short tail (t) is recessive to the allele for long tail (T). What would be the genotype of a mouse that was homozygous for black fur and short tail?
Black fur in mice (B) is dominant to brown fur (b). Short tails (T) are dominant to long tails (t). What percentage of the progeny of crosses BbTt × BBtt will be expected to have black fur and long tails? (enter a number only)
3. In cats, the B allele codes for black fur, and the b allele codes for orange fur. The gene is located on the X chromosome. However, the genotype XB/Xb results in fur with a mottled appearance called tortoise-shell. Suppose a tortoise-shell female is crossed with a black male. a. What are the parental genotypes? b. What phenotypic ratios would be expected in the offspring? c. What is the mode of inheritance? d. A rich client wants a tortoise-shell male....
