Answer:
a. Tt - Gametes T and t
b. GG - Gametes G only
с. ff - Gametes f only
Step-by-step explanation:
Gamete formation or meiosis is a cellular division of the reproductive cells in sexually reproducing organisms. Meiosis produces daughter cells (gametes) with a reduced number of chromosomes (by half) as the parent cell.
According to Gregor Mendel in his law of Segregation, he stated that the alleles of a gene get separated into gametes in such a way that only one allele can be found in the gamete. The separation is random and equal.
Based on this, a heterozygous parent Tt will produce gametes with alleles T and t in an equal proportion. Since parents GG and ff contains the same alleles in their genotype, they will produce gametes with only one type of allele each i.e. Gametes with alleles G and f respectively.
