Explanation:
Homozygous means same while heterozygous means different.
3.) If a man and a woman both have brown eyes, yet they have a child with blue eyes, both parents must be heterozygous brown.
4.) Bob is heterozygous R and Sally is homozygous r. This is because Rolling your tongue is dominant over not rolling your tongue. For Bob to be able to roll his tongue while having a mother who cannot, he must be Rr. If Sally cannot roll her tongue she must be rr.
5.) The man is heterozygous black. His wife is homozygous blonde. Black hair is dominant to blonde hair. If the man had black hair and his mother had blonde hair, he must be Bb. His wife having blonde hair means she is bb.
