There are three colored feathers colors for birds. A bird with red fur reproduces with a bird that has blue feathers .The offspring are all birds with purple feathers. Two bird with purple feathers reproduce, and their offspring include 15 birds with purple fur, 7 birds with red feathers, and 8 birds that have blue fur. Imagine if you crossed a bird with purple feathers to a bird with red fur, what proportions, would you predict to find?

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.
