Petunia flower color is governed by two alleles, but neither allele is truly dominant over the other.  Petunias with the genotype RR are red-flowered, those that are heterozygous (RW) are pink, while those with the (WW) genotype have white flowers.  This is an example of incomplete dominance. a. If a white-flowered plant is crossed with a red-flowered plant, what is the genotypic ratio of the F1. b. What is the phenotypic ratio of the F1. c. If two of the F1 offspring were crossed, what phenotypes would appear in the F2?. d. What would be the genotypic ratio in the F2 generation?

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.
