An alien species has been discovered; they call themselves the Blobs. Using information they have provided us, we are trying to learn their genetic characteristics. So far, we have learned that 3 antennae are dominant over 1 antenna and this is an autosomal condition. Green blob color is dominant over blue blob color and this is a sex-linked trait. Use this information to construct a pedigree about a family of blobs. Thera, her mother, and both of Thera’s maternal grandparents have 1 antenna. Thera’s man-blob, Lotka, has 3 antennae, as does his father and paternal grandfather. Lotka’s mother has 1 antenna. Provide a pedigree for all individuals and provide possible genotypes and phenotypes for their 4 baby-blobs.            Volta (a boy-blob) is blue. So are his mother and maternal grandmother. His father and maternal grandfather are both green. Volta’s wife is heterozygous. What color is she? Provide a pedigree for this family and describe the possible genotypes and phenotypes for their 6 offspring, by sex.

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.
