In the garden pea, yellow pods (yp) are recessive to green pods (Yp) and straight tendrils (ct) is recessive to curled tendrils (CT). A plant with yellow pods and straight tendrils was crossed with a true breeding plant with green pods and curved tendrils. The F1 offspring were then test-crossed to plants with yellow pods and straight tendrils. The following offspring were observed: # offspring phenotype 327 yellow pod, straight green pod, curled yellow pod, curled 336 17 19 green pod, straight

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.
