The earlobe trait is denoted by E and e alleles, whereas the eye trait is denoted by B and b alleles. The Punnet square allows identifying the expected proportions in the progeny.
<h3>The Punnett square and inheritance </h3>
The Punnett square is a diagram used to represent the gamete combinations in order to estimate genotypes and phenotypes in the progeny.
The earlobe trait is denoted by E and e alleles, thereby there are two types of gametes in heterozygous individuals.
In this case:
E e
E EE Ee
e Ee ee
Moreover, the eye trait is denoted by B and b alleles, thereby there are two types of gametes in heterozygous individuals.
In this case:
B b
B BB Bb
b Bb bb
