The number of stripes on a tiger exemplifies a polygenetic inheritance pattern. Five loci contribute to the stripe pattern. Each active allele adds 7 stripes to a male and 5 stripes to a female and having the genotype a a bbgghhee produces a baseline number of stripes of 40 for males and 35 for females. What is the number of stripes for a male with the genotype A a bb G ghhE e? 55 stripes a. 61 stripes Ob. 50 stripes Oc. 56 stripes 68 stripes e.

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.
