Answers

The  gametes for GgTt and ggtt would be

GgTt - GT, Gt, gT, gt

ggtt- gt, gt, gt, gt

Explanation:

Given Genotype -

GgTt

ggtt

The allele for these two genotypes are -

GgTt - GT, Gt, gT, gt

ggtt- gt, gt, gt, gt

A punnet square representing the cross between these two genotype is given below-

GT          Gt              gT      gt

gtGgTtGgtt      ggTt      ggtt

gtGgTtGgtt      ggTt      ggtt

gtGgTtGgtt      ggTt     ggtt

gtGgTtGgtt      ggTt     ggtt

Hence, the  gametes for GgTt and ggtt would be

GgTt - GT, Gt, gT, gt

ggtt- gt, gt, gt, gt

The genotypes of parents are ggtt.
they have 2 alleles and are capable of forming only one type of gamete.
ggtt   - gt 
since both plants have genotypes ggtt
both can form only one type of gamete , that is gt
Therefore answer is one..one
They can produce 3 types of gametes; gggg, ggtt and tttt in the ratio of 1:2:1. As shown in the table attached, the tetraploid parents produce diploid gametes that combine to form genetically varied offspring.
The genotypes may differ from that of the genotype depending on the interaction of the dominant, recessive and codominant alleles.
