In turkeys a dominant gene R produces the familiar bronze coloured feathers; its recessive allele r results in red coloured feathers. Another dominant gene H results in normal feathers; its recessive allele h produces feathers without webbing, so that they resemble tufts of hair. A crossing between a male homozygous bronze with normal feathers and a female red with feathers without webbing in turkeys was made. Summarize the phenotypes of the expected F2 offspring

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.
