Assume that plant height is determined by a pair of alleles at each of two loci (A and a, B and b) that are additive in their effects.  Further assume that each allele represented by an uppercase letter contributes 6 feet to height and that each allele represented by a lowercase letter contributes 2 foot to height.  If a plant with genotype Aabb is crossed to a plant with genotype aaBb, what heights are expected in the progeny?     1/216ft : 1/2 12ft     1/4 16ft : 1/2 12ft : 1/4 8ft     1/4 20ft : 1/2 16ft : 1/4 12ft     1/4 24ft : 1/2 20ft : 1/4 16ft     1/2 20ft : 1/2 16ft

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.
