The genotype of the parents for the given offspring. Introduction: According to Mendelian inheritance , a single character is controlled by one or more pairs of alleles. These alleles can be either dominant or recessive. Usually, dominant allele masks the expression of recessive allele. Recessive allele is expressed only in homozygous condition but dominant allele is expressed both in homozygous and heterozygous condition.

Features of a Concept Features of a Concept Characteristics are discrete; that is, they are unitary. Genetic features have alternative forms, and each feature is inherited from one of the two parents. These are called alleles. One allele is dominant over the other allele. The dominant allele is reflected in the phenotype. Random segregation creates the gametes. The heterozygotic individuals produce gametes with an equal frequency of both alleles. Genes are unlinked; that is, different traits arise from the independent assortment.

When roan cattle are mated, 25% of the offspring are red, 50% are roan, and 25% are white. Upon examination, it can be seen that the coat of a roan cow consists of both red and white hairs. What were the original parental genotypes?

In cocker spaniels, solid coat color is dominant over spotted coatcolor. If two heterozygous dogs were crossed to each other, whatwould be the probability of the following combinations of offspring?A. A litter of five pups, four with solid fur and one with spotted fur.B. A first litter of six pups, four with solid fur and two with spotted fur, and then a second litter of five pups, all with solid fur.C. A first litter of five pups, the firstborn with solid fur, and thenamong the next four, three with solid fur and one with spottedfur, and then a second litter of seven pups in which the firstborn is spotted, the second born is spotted, and the remainingfive are composed of four solid and one spotted animal.D. A litter of six pups, the firstborn with solid fur, the second bornspotted, and among the remaining four pups, two with spottedfur and two with solid fur

The allele A is brown fur and the allele a is white fur. In a mating between a heterozygous male and a heterozygous female, what is probability that they will have an offspring with brown fur and what is the probability they will have an offspring with white fur?
