Exam 3: Mendelian Genetics

The fundamental Mendelian process that involves the separation of contrasting genetic elements at the same locus would be called ________.

Two organisms,AABBCCDDEE and aabbccddee,are mated to produce an F₁ that is self-fertilized.If the capital letters represent dominant,independently assorting alleles: a) How many different genotypes will occur in the F₂? b) What proportion of the F₂ genotypes will be recessive for all five loci? c) Would you change your answers to (a)and/or (b)if the initial cross occurred betwee $\text { AAbbCCddee } \times a a B B c c D D E E$ n parents? d) Would you change your answers to (a)and/or (b)if the initial cross occurred betwee $A A B B C C D D E E \times a a b b c c d d E E$ n parents?

What meiotic process,relative to the number of chromosomes of a given species,accounts for a significant amount of genetic variation in gametes?
