Final answer:
An Individual with the genotype Tt can produce two types of gametes through meiosis - ones with the T allele and ones with the t allele. The correct answer is C. T and t.
Step-by-step explanation:
If an individual has the genotype Tt, then this person can produce only two types of gametes with respect to this gene. During gamete formation, which occurs through a process known as meiosis, each allele segregates independently into separate gametes. Since 'Tt' represents a heterozygous genotype, where 'T' is one allele and 't' is another, the gametes formed can either contain the 'T' allele or the 't' allele but not both.
Therefore, the correct answer to the question is C. T and t, indicating that one gamete will carry the dominant 'T' allele and the other gamete will carry the recessive 't' allele.
