Manx cats have shortened tails due to the autosomal dominant allele M that affects spine formation. This allele is lethal in homozygotes. The autosomal recessive allele m leads to normal tail development. What is the genotype for a Manx cat?Multiple choice question.MmMMmm

Manx cats have shortened tails due to the autosomal dominant allele M that affects spine formation. This allele is lethal in homozygotes. The autosomal recessive allele m leads to normal tail development. If two Manx cats are mated to each other, what is the fraction of offspring expected to have normal tail lengths?Multiple choice question.None of the offspring1/4All of the offspring1/21/3

Rooster feathering in chickens is inherited with the autosomal recessive allele r. Hen feathering is inherited with the autosomal dominant allele R. The trait is sex-limited, only males will show rooster feathering. A rooster-feathered male is mated to a hen-feathered female. All of the male offspring have rooster-feathering. What is the genotype of the hen-feathered mother?Multiple choice question.RRRrrr

solve this question by using punnet square In cats, the gene for fur colour has two alleles. The dominant allele (A) codes for black fur while the recessive allele (a) codes for orange fur. The female cat is heterozygous and the male is homozygous recessive. What would the possible genotypes and phenotypes of their kittens be?

The development of scurs, small horn-like growths on the faces of cattle, is inherited with the sex-influenced alleles ScP𝑆𝑐𝑃and ScA𝑆𝑐𝐴. The allele ScP𝑆𝑐𝑃stands for scurs being present and is dominant in males and recessive in females. The allele ScA𝑆𝑐𝐴stands for scurs being absent and is dominant in females and recessive in males. Suppose a male with scurs is mated to a female with no scurs. All of the male offspring, as well as 50% of the female offspring, have scurs. What are the genotypes of the parents in this cross?Multiple choice question.ScPScP𝑆𝑐𝑃𝑆𝑐𝑃 male x ScAScA𝑆𝑐𝐴𝑆𝑐𝐴ScPScP𝑆𝑐𝑃𝑆𝑐𝑃 male x ScPScA𝑆𝑐𝑃𝑆𝑐𝐴 femaleScPScA𝑆𝑐𝑃𝑆𝑐𝐴 male x ScPScA𝑆𝑐𝑃𝑆𝑐𝐴 femaleScPScA𝑆𝑐𝑃𝑆𝑐𝐴 male x ScAScA𝑆𝑐𝐴𝑆𝑐𝐴 female

The height of pea plants is controlled by a single gene with two alleles: a dominant tall allele (T) and a recessive short allele (t). Which of the following is the genotype of a homozygous dominant pea plant?TtttTXTT 4
