A responsible for anterior morphology in an organism is inherited as maternal effect gene. It has two allele: H (normal) and h (a recessive allele that cause small head). A female organism with normal head mates with a true-breeding male with small head. All the offspring have small heads. What should be the genotype of mother and offspring? a. Mother- Hh, and Offspring- hh b. Mother- hh and offspring Hh c. Mother-hh and offspring- hh d. Mother- hh and offspring- Hh

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.
