What phenotypic ratio is expected in the adult progeny

Reference no: EM1397148

Normal leg size, characteristic of the Kerry type of cattle, is produced by the homozygous genotype dd. Short-legged Dexter type cattle possess the heterozygous genotype Dd. The homozygous genotype DD is lethal, producing grossly deformed stillbirths called "bulldog calves". The presence of horns in cattle is governed by the recessive allele of another gene locus p, the polled condition (absence of horns) being produced by its dominant allele P. In matings between polled Dexter cattle of genoytpe DdPp, what phenotypic ratio is expected in the adult progeny?
