In rabbits, the dominant allele B causes black fur and the recessive allele b causes brown fur; for an independently assorting gene, the dominant allele R causes long fur and the recessive allele r (for rex) causes short fur. A homozy- gous rabbit with long, black fur is crossed with a rabbit with short, brown fur, and the offspring are intercrossed. In the F2, what proportion of the rabbits with long, black fur will be homozygous for both genes? Is there a faster way to do this than to write every genotype out?

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.
