Are blue eyes heterozygous or homozygous?
Being homozygous for a particular gene means you inherited two identical versions. It’s the opposite of a heterozygous genotype, where the alleles are different. People who have recessive traits, like blue eyes or red hair, are always homozygous for that gene.
Are blue eyes dominant or recessive?
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.
What is blue eye genotype?
The different variants of genes are referred to as alleles. The gey gene has one allele that gives rise to green eyes and one allele that gives rise to blue eyes. The bey2 gene has one allele for brown eyes and one for blue eyes.
What is an example of a heterozygous trait?
Heterozygous means that an organism has two different alleles of a gene. For example, pea plants can have red flowers and either be homozygous dominant (red-red), or heterozygous (red-white). If they have white flowers, then they are homozygous recessive (white-white).
Can a brown-eyed father and a blue-eyed mother have a blue-eyed child?
The only way to present blue eyes is to inherit two copies of the blue-eyed gene. However, brown-eyed parents can pass a recessive blue-eyed gene. Therefore, two brown-eyed partners can birth a blue-eyed baby. Brown eyes + blue eyes = 50% chance of blue eyes, but only if the brown-eyed parent carries a blue-eyed gene.
Can 2 brown-eyed parents have a blue-eyed child?
Brown (and sometimes green) is considered dominant. So a brown-eyed person may carry both a brown version and a non-brown version of the gene, and either copy may be passed to his children. Two brown-eyed parents (if both are heterozygous) can have a blue-eyed baby.
Can two blue-eyed parents have a green eyed child?
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…
What do blue eyes represent?
Therefore, they are sometimes attributed to “eternal youth.” Blue eyes are heralded by some to be the most desirable and attractive of eye colors, and those who have them possess a calm and peaceful personality. Blue eyes are also representative of knowledge.
