Answer 2

The genotype of a tall pea plant with round seeds is TtRr. The gametes produced will be TR, Tr, tR, tr (option-4).

• Genotype is defined as the genetic makeup of an organism.
• In TtRr, T and R depict the dominant allele for height and seed shape character respectively. t and r depict recessive alleles for the same.
• TtRr, is a heterogeneous condition, in which both the dominant allele and recessive allele of a character are existing together.
• The Number of gametes = 2ⁿ, where n is the number of heterozygotes present in a genotype.
• In TtRr, there are two heterozygotes, one is Tt and another is Rr.
• Therefore, Number of gametes = 2² = 4
• These gametes which are formed after independent assortment and segregation, are TR, Tr, tR, tr.
