Three coat-color patterns that occur in some breeds of horses aretermed cremello (beige), chestnut (brown), and palomino (goldenwith light mane and tail). If two palomino horses are mated, theyproduce about 1/4 cremello, 1/4 chestnut, and 1/2 palomino offspring. In contrast, cremello horses and chestnut horses breed true.(In other words, two cremello horses will produce only cremellooffspring, and two chestnut horses will produce only chestnut offspring.) Explain this pattern of inheritance.

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.
