Knowing that brown eyes dominate over blue, and dark hair – over light, write the genotypes for the following individuals: a – blue eyes and blonde hair b – brown eyes and blonde hair c – brown eyes and dark hair d – blue eyes and dark hair.

Let’s designate the gene for the development of brown eyes as S, and the gene for the development of blue eyes as s.

Let’s designate the gene that causes the development of dark hair as R, then the gene that causes the development of light-colored hair will be designated as r.

a) blue eyes and blonde hair – ssrr;

b) brown eyes and blonde hair – Ssrr, or SS rr;

c) brown eyes and dark hair – SSRR, or SsRr, or SSRr, or SSRR;

d) blue eyes and dark hair – ssRR, or ssRr.
