Gametes of the parents would be:

PpTt : PT ; Pt ; pT ; pt

Pptt : Pt ; Pt; pt ; pt


You can do this easily using the FOIL method on each genotype. Just like in math, F stands for first; O stands for outside; I stands for inside; and L stands for last. I'll do one parent genotype and maybe you will understand how this was done:


GENOTYPE: <em>PpTt</em>


<em>F- </em><em>irst of each pair. P and T</em>


P p T t


Gamete: <em>PT</em>


<em>O </em><em>- utside allele of the pair. P and t</em>


P p T t


Gamete: Pt


<em>I - </em><em>inside alleles of the pair. p and T</em>


P p T t


Gamete: pT


<em>L</em><em>-ast or end allele of each pair. p and t</em>


P p T t


Gamete: pt
