Normal leg size, characteristic of Kerry-type cattle, is produced by 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 horn) being produced by its dominant allele P. In matings between polled Dexter cattle genotype DdPp, a) what expected ratio is expected in the adult progeny? b) what percentage of the progeny will carry the lethal allele

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
