Document Summary
Tetraploid aaaa: homozygous inherited identical alleles at one or more loci, identical alleles in homolog chromosomes, diploid aa. Gregor mendel: traits studied were qualitative traits. Ex, flower color, seed color, plant height: single gene, no environmental effects, investigated the inheritance of elements or units in pea plants. Punnet squares are used to determine possible gametes from a parent or set of parents. Multiplication rule: the probability of two events to occur at the same time is equal to the product of their individual. Possible combinations of heads (h) and tails (t) when tossing a penny (p) and a nickel (n) at the same time: 4 possible outcomes, (ph:nh)= (1/2)(1/2)= , (pt:nh) (1/2)(1/2)= , (ph:nt)=(1/2)(1/2)= , (pt:nt) = (1/2)(1/2)= . Ex. rolling a 3 or 4 on a single dice roll. (1/6 + 1/6 = 2/6) Sum rule: the probability of one or more outcomes occurring with a single event. Binomial distribution: utilizing both sum rule and multiplication rule.
