Question

In pea plants being tall (T) is dominant over being short (t). Also in pea plants having green pods (G) is dominant over yellow pods (g). One plant named George, is heterozygous for height (Tt) and homozygous for yellow pods (gg). George is crossed with another plant named Cici that is homozygous for height (TT) and heterozygous for green pods (Gg). What gametes will the plant named George produce

Answer 1

Answer:

1 Tg: 1 tg

Explanation:

The plant named George is heterozygous for height (Tt) and homozygous for yellow pods (gg). Therefore, its genotype is Ttgg. The two alleles for the height (T and t) would segregate from each other and will be distributed to different gametes. The presence of similar gametes for pod color (only "g") would make this plant to make all the gametes having "g" allele. Therefore, 50% gametes from this plant would have one copy of T and one copy of the g allele while the rest 50% would have one copy of "t" and one copy of the "g" allele.  

Gametes produced by George= 1 Tg: 1 tg
