1. Alleles of the gene that determines seed coat patternsin lentils can be organized in a dominance series:marbled > spotted = dotted (codominant alleles) >clear. A lentil plant homozygous for the marbled seedcoat pattern allele was crossed to one homozygous forthe spotted pattern allele. In another cross, a homozygous dotted lentil plant was crossed to one homozygous for clear. An F1 plant from the first cross wasthen mated to an F1 plant from the second cross.a. What phenotypes in what proportions are expectedfrom this mating between the two F1 types?b. What are the expected phenotypes of the F1 plantsfrom the two original parental crosses?

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.
