All crosses involve many more than one character. So far, only one character has been examined to help simplify the principles involved. Now, two pairs of alleles or two characters will be examined at the same time. In working the following problem, each pair of characteristics is on a different chromosome and will be inherited independently of the other (Principle of Independent Assortment). Problem 1: In garden peas, a homozygous recessive male plant with wrinkled, green seeds is crossed with a plant that is homozygous dominant for round, yellow seeds. Use this information to complete the following: Male phenotype= genotype= gametes= F2 phenotype= genotype= gametes= F, phenotype= F₁ genotype = Female Figure 12.10 Punnett Square for F₁ The F, genotype should be all RrYy. The gametes are formed from various combinations of these alleles. Each gamete must have one R and one Y. For example, the F, male gametes will be RY, Ry, rY, ry. Would the female gametes be the same as the male or different? Self-fertilize F, to obtain F₂. F2 phenotypic ratio=

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.
