(a) E is the gene for brown eye colour and e is the gene for blue eye colour. Which gene is (i) recessive, and (ii) dominant?(b) Both father and mother have the genes Ee in their cells. What colour are their eyes?
(c)Which combination of genes in the zygote will produce children with blue eyes?
(d)Which combinations of genes in the zygote will produce children with brown eyes?
(a) (i) Gene e for blue eye colour is recessive, and (ii) Gene E for brown eye colour is dominant.
(b) Both father and mother containing the genes Ee in their cells are with brown eye colour (because gene E is dominant over gene e).
(c) In the zygote, gene ee will produce children with blue eyes.
(d) In the zygote, heterozygous form of gene Ee and homozygous form of gene EE will produce children with brown eyes.
