Final answer:
The types of gametes that can be formed by an individual with genotype AaBbcc are ABc, Abc, aBc, and abc. This results from the process of meiotic segregation of each gene's alleles, following Mendel's principle of independent assortment for unlinked genes. Each heterozygous gene (Aa, Bb) has two possible alleles that can segregate, while the homozygous gene (cc) contributes the same allele to all gametes.
Step-by-step explanation:
Gamete Formation
The different types of gametes that can be formed by an individual with genotype AaBbcc are ABc, Abc, aBc, and abc. This is due to the formation of gametes by meiosis, where the paired alleles for each gene segregate independently during the process and go to different gametes. This concept aligns with the Mendelian principle of independent assortment for genes that are unlinked.
For each gene, we consider the alleles involved (Aa, Bb, cc). The allele c is homozygous recessive, so all gametes will have c. However, for the A and B alleles that are heterozygous (Aa and Bb), each allele can segregate into gametes separately. As a result, there's a 50 percent chance for gametes to get either the A or a allele and similarly a 50 percent chance to get either the B or b allele.
Probability and Fertilization
The probability that one type of gamete (for example, containing the B allele) will join with any other type of gamete from another parent is a matter of chance, much like flipping a coin. A heterozygous (AaBb) cross with another heterozygous (AaBb) or a homozygous recessive (aabb) individual can produce offspring with various combinations of alleles, and these combinations determine the offspring's genotype and phenotype.
Thus, under the assumption of independent assortment, the possible gametes produced will reflect different combinations of A, a, B, and b alleles, resulting in gametes with the following genotypes: ABc, Abc, aBc, and abc.
