Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If one parent has blue eyes and one parent has green eyes, the offspring will definitely have blue eyes.
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Yes. The parent with the green eyes most likely has the recessive gene for blue eyes. Their own eyes show up as green as green is dominant. parents pass on only one gene to their children and would therefor have passed on the gene for blue eyes.

Detailed explanation-2: -Blue will always be recessive. If both parents have a blue allele, it is likely that the child will have blue eyes. However, if one parent has green eyes and the other blue, your child will most likely have green eyes, as green is dominant over blue.

Detailed explanation-3: -First, the answer is yes to both questions: two blue-eyed parents can produce green or brown-eyed children. Eye color is not the simple decision between the brown (or green) and blue versions of a single gene. There are many genes involved and eye color ranges from brown to hazel to green to blue to…

Detailed explanation-4: -A couple’s children can have almost any eye color, even if it does not match those of either parent. Currently it is thought that eye color is determined by about six genes, so you can imagine how inheritance of eye color becomes very complicated.

Detailed explanation-5: -One parent with blue eyes and one parent with green eyes: 50% of chance of baby with blue eyes, 50% chance of baby with green eyes, 0% chance of baby with brown eyes.
