if pea plants with the genotype ttyy are crossed with pea plants with the genotype ttyy, what portion of the offspring will be expected to have the ttyy allele combination?

Respuesta :

. 25% of the progeny are anticipated to carry the TTYy allele combination.

A cross as well as breeding experiment's genotypes can be predicted using the Punnett square, a diagram with squares. This square bears Reginald C. Punnett's name, who created this invention in 1905.

There will be two heterozygous plant crosses:   T         T                        Y         y

T   TT     TT                   y   Yy     yy

t    Tt       Tt                   y   Yy      yy

The ratio of TT=          The ratio of Yy=  

25% of all offspring from the cross between TTYy and Ttyy are represented by the ratio of TT= The ratio of Yy= The overall ratio of TTYy =.

As a result, the progeny is heterozygous. 25% of the progeny are anticipated to carry the TTYy allele combination.
