In black-eye pea, the T and P genes are linked and 20 m.u. and P_ = pennate leaves, pp = oval leaves. T_ = thick pods, tt = narrow pods. A PpTt plant with the dominant alleles in REPULSION, is SELFED. The probability of an oval-leafed, narrow podded plant in the progeny is: HINT: it helps if you draw the chromosomes and the possible gametes! 1% 25% 10% 5% 40%

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.
