Flower position, stem length, and seed shape are three charactersthat Mendel studied. Each is controlled by an independentlyassorting gene and has dominant and recessive expression as indicated in Table 14.1. If a plant that is heterozygous for all threecharacters is allowed to self-fertilize, what proportion of theoffspring would you expect to be each of the following? (Note:Use the rules of probability instead of a huge Punnett square.)(a) homozygous for the three dominant traits(b) homozygous for the three recessive traits(c) heterozygous for all three characters(d) homozygous for axial and tall, heterozygous for seed shape

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.
