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.

In certain species of flies, eye color is controlled by sim-·ple dominance by a single pair of alleles. A red-eyed fly was crossed with a white-eyed fly, both of whose parents had white eyes. All of their offspring (both female and male) had red eyes.a. Which is dominant, the allele for red eyesor the allele for white eyes?b. What is the genotype of the white-eyed parents?c. If the white-eyed parent was mated with one of the red-eyed offspring, what phenotypic ratio wouldyou expect regarding eye color?

In dogs, a dominant gene (1) determines white coat, and a recessive gene (i) gives colored coat. In the presence of ii the coat color is black due to the dominant gene B, or brown due to the recessive gene b. Two dogs both having the Bbli genotype were mated. Answer the following questions and show complete solutions to support your answers. Use the branching method whenever applicable. What is the phenotypic ratio of the offspring? What type of gene interaction is exhibited by the coat color in dogs? What would be the probability of getting dogs that are pure-breeding for a black coat color? 3. a. b. C.
