Question

Determine the parental genotypes and proportion of offspring genotypes for locus 2. What are the genotypes of the parents with respect to locus 2 (i.e., alleles B and b)

Answer 1

Answer and Explanation:

Alleles are the different varieties of genes. For every gene, somatic cells have two alleles.An allele that is not expressed by an organism might be passed to the offspring of The organism provides one allele.

It is difficult to conclude which two alleles of a gene exist within the chromosomes of organisms.  that organism and can express in the next generation.

The parental genotypes can be determined by PUNNETT SQUARE, in which we use two letters to signify the genotype.

As the white throat code and the red throat code are alleles.

A lowercase letter represents the recessive form of a gene (allele), and a capital letter represents the dominant form of a gene (allele). For example, for the red-throated bird, white throat is a recessive trait, and red throat is a dominant trait.

There are basic steps of using Punnett Square. Step one is to determine the parent organism genotypes then write down “mating.” Draw a p- square. For each parent, split the letters of the genotype. Then place them outside the p-square. By filling the p-square, determine the genotype of the offspring. Then summarize results.
