Answers. Best Answer: 1 anisogamy (reproduction by the union or fusion of two differing gametes (especially differing in size) 2 Gonad is the generic term for either testes or ovaries 3 Gametes are haploid 4 Disease and disorders are passed on.
AaBbCc 8 kinds of gametes = ABC, ABc, AbC, Abc, aBC, abC, aBc , and abc in equal proportions h. AaBbCcDdEeFf 32 different kinds of gametes in equal proportions 2. Based on your answer in question 1, propose a general rule for determining the number of different gametes organisms like those described in question 1 can produce. Number of different kinds of gametes = 2 n , where n = number of heterozygous alleles (genes).
