In the gene that controls whether a cat’s ears curl, the dominant Cu+ allele produces curled ears, while the recessive Cu allele produces straight ears. In the gene that controls fur color, the dominant G+ allele produces black fur, while the recessive G allele produces grey fur. Both genes are on autosomes. Imagine a grey cat with curled ears mates with a black cat that has straight ears. Half the F1 offspring are black, while half are grey. All F1 offspring have curled ears. Please give me the genotypes of the two parents.

Can someone show me steps by steps? Please draw a punnett square, if possible

    In cats, curled ears result from an allele (Cu) that is dominant over an allele (cu) for normal ears. Black color results from an independently assorting allele (G) that is dominant over an allele for gray (g). A gray cat homozygous for curled ears is mated with a homozygous black cat with normal ears. All the F1 cats are black and have curled ears. a. If two of the F1 cats mate, what phenotypes and proportions are expected in the...

    Let's say that in chipmunks, the allele for a black tail stripe (B) is dominant to the allele for a white tail stripe (b), and that the allele for patches of fur on an ear ("ear tufts") is determined by a recessive allele (e), with plain ears resulting from a dominant allele (E). A chipmunk that is homozygous recessive for the tail trait and heterozygous for ear morphology mates with a chipmunk that is heterozygous for both tail and ear...

    The dominant allele of gene A encodes for long ears in rabbits whereas the recessive allele encodes for short ears. The dominant allele for gene B encodes for pointy ear tips while the recessive encodes for round tips. Genes A and B are 70 map units apart. A rabbit with AB/ab genotype is test crossed. What phenotypic ratios do you expect to see in the F1? Select one: a. 3 long and pointy : 1 short and round b. 20...

    The recessive gene sh produces shrunken endosperm in corn kernels and its dominant allele sh+ produces full, plump kernels. The recessive gene c produces colorful endosperm and its dominant allele c+ produces colored endosperm. Two homozygous plants are crossed, producing and F1 all phenotypically plump and colored. The F1 plants are testcrossed and the following offspring were produced: 149 shrunken, colored, 4035 shrunken, colorless, 152 plump, colorless and 4032 plump, colored. a. What were the phenotypes and genotypes of the...

    Short Answer 28. Given the following information: Tall (T) is dominant over short (t), brown hair (B) is dominant over red hair (b), and a great sense of humor (H) is incompletely dominant over a being not funny (h). (Note: the inheritance patterns described are not factual!). The following cross is performed: Dr. Peter Linder (TtBbHH) x Dr. Carol Linder (TTbbHh) a. What is the probability that at least one of their children will be of tall, red- haired and...

    In mice, the dominant allele Gs of the X-linked gene Greasy produces shiny fur, while the recessive wild type Gs+ allele determines normal fur. The dominant allele Bhd of the X-linked Broadhead gene causes skeletal abnormalities including broad heads and snouts, while the recessive wild-type Bhd+ allele yields normal skeletons. Female mice heterozygous for the two alleles of both genes were mated with wild-type males. Among 100 male progeny of this cross, 49 had shiny fur, 48 had skeletal abnormalities,...

    For this problem: In mice, a single gene controls yellow fur color. The Y allele is dominant and produces yellow fur, the y allele is recessive and results in white fur. When you cross two heterozgyous yellow mice (Yy x Yy), you find that you get 20 yellow offspring and 10 white offspring. That should tell you what kind of genetics and the probability of getting a single yellow or white mouse. What is the probability first picking a first...

    6. In tigers, a dominant allele (W) is responsible for the expression of the normal orange pigment. Individuals that inherit twe recessive alleles (w) lack the normal orange pigment in their fur, appearing white with black stripes. A pair of normally colored parewis produces a cub that is white with black stripes and scab that is orange with black stripes. What are the possible genotypes of the cube? b. What are the possible genotypes of the parents? 6. Explain your...

    that's all the professor give 3. In pigs, black hair (B) is dominant to red hair (b). Erect ears (E) are dominant to drooping ears (e). What are the expected proportions of the different phenotypes resulting from a mating between two pigs heterozygous for both traits? SHOW A PUNNETT SQUARE 4.
