During his research he found that the chromosomes of teosinte and maize possess higher similarity and also show signs of intercross ability of the two species and hence confirmed that wild teosinte is an ancestor of domesticated maize.  

He later concluded that there are only 4 to 5 genes that make these two species different from each other rest all is similar.

Yuliya22 [10]

Answer:

The parents must be Tt, Tt

Explanation:

Based on these results, we can conclude that each of the parents will have one dominant (T) and one recessive allele (t). We can prove this by drawing the Punnett square:

     T      t

T    TT   Tt

t     Tt     tt

We can see that the offspring will have the Tt genotype in two cases, the TT genotype in one case, and the tt genotype in one case, as well. Now we need to do some basic math. Two out of four is 50% (Tt - 50%), and one out of four is 25% (TT - 25%, tt - 25%).

This means that the parents must be Tt, Tt.
