The extrachromosomal inheritance is otherwise known as cytoplasmic inheritance. The transmission of the gene occurs in this type of inheritance is outside the nucleus. It occurs in organelles such as plastids, chloroplast, and mitochondria.

- Calculate the probability of producing an Aabb individualfrom an AaBb × AaBb cross.A man whose father was hemophilia, but whose own blood clotting time is normal, marries a women with no record of hemophilia in her pedigree. What is the chance of hemophilia in their children?Please give the expected genotypic and phenotypic ratio of offspring from a cross between a person with Type AB blood and a person with Type O blood.
- Explain the results of this cross.If a male who is non-hemophiliac is crossed with a female carrier of both colorblindness and hemophilia, what is the probability that a female child will be phenotypically normal?List the 6 possible genotypes of the four blood types. Identify the parentalgenotypes that could produce children with blood type AO.
