-
Alleles and Eye Coloration
There are a number of genes which can be concerned in figuring out eye colour, however a very powerful gene is the OCA2 gene. This gene codes for a protein known as the P protein, which is answerable for producing melanin. Melanin is the pigment that provides eyes their colour. -
Dominant and Recessive Alleles
The OCA2 gene has two fundamental alleles: a dominant allele (B) and a recessive allele (b). The dominant allele codes for a useful P protein, whereas the recessive allele codes for a non-functional P protein. -
Eye Coloration Inheritance
A baby inherits one allele from every dad or mum. If a baby inherits two dominant alleles (BB), they’ll have brown eyes. If a baby inherits one dominant allele and one recessive allele (Bb), they’ll have hazel eyes. If a baby inherits two recessive alleles (bb), they’ll have blue eyes. -
