Can parents with brown eyes have a blue-eyed child?
Can parents with brown eyes 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.
What eye Colour is dominant?
The allele for brown eyes is the most dominant allele and is always dominant over the other two alleles and the allele for green eyes is always dominant over the allele for blue eyes, which is always recessive.
Do blue eyes overpower brown?
The brown version of gene 1 is dominant over the blue one. The way geneticists represent these two different versions of this eye color gene are B for brown and b for blue (the capital letter is always the dominant, the lowercase, the recessive). So you will have brown eyes with either BB or Bb and blue eyes with bb.
Do brown eyes overpower Blue eyes?
The brown-eye gene is dominant and overrides the blue-eye gene, so all the children have brown eyes. However, if the father also carries a blue-eye gene and a child inherits one from each parent, that child will have blue eyes.
Do brown eyes have lipochrome?
Melanin is a brown pigment, and lipochrome is a somewhat yellowish pigment. So for instance, people with brown eyes have a higher melanin concentration that makes their iris appear brown or almost black in some cases. Blue eyes, in contrast, have very little melanin and lipochrome.
Which parent determines eye color?
A persons eye color is determined by genetics, or the genes they receive from their parents. But, it isn’t as simple as a blue eyed parent makes a blue eyed baby. Since each person receives genetic information from both parents, a child can have a completely different eye color than both of their parents.
What is the genotype of brown eyes?
Therefore any individual with blue eyes contains two recessive alleles. If a dominant allele (Such as the allele for Brown eyes) is present within any individuals genotype, the individual will have brown eyes.
Will My Baby have blue eyes?
Eye Color and Genetics. For example, if you and your partner’s eyes are brown, but one of you had a parent that has blue eyes, there is still a small chance that your baby’s eyes will stay blue. If you have blues and your partner has brown, then your baby’s eyes have a 50% chance of either one.
