4) Consider the production of flower color in the Japanese morning glory (Pharbitis nil). Dominant alleles of either of two separate genes (A_bb or aaB_) produce purple petals, A_B_ produces blue petals, and homozygous recessives for both genes produce scarlet petals. Deduce the genotypes of parents and progeny in the following crosses: (Tabulate your answers). PARENTS a) blue x scarlet b) purple x scarlet PROGENY 1/4 blue: 1/2 purple : 1/4 scarlet 1/2 purple: 1/2 scarlet

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.
