    Mendelian Genetics * Pea plants have several advantages for genetics. * Pea plants are available in many varieties with distinct heritable features (characters) with different variants (traits). * Another advantage of peas is that Mendel had strict control over which plants mated with which. * Each pea plant has male (stamens) and female (carpal) sexual organs. * In nature‚ pea plants typically self-fertilize‚ fertilizing ova with their own sperm.

Once an at-risk sib is known to be unaffected‚ the risk of his/her being a carrier is 2/3”(Strauss). This represents a Monohybrid Cross. [pic]This relates to meiosis and fertilization because the passing of the traits to the four daughter haploid cells from the diploid parents. It happens just as a punnet square one child has a chance of being affected‚ another has
