If a child has blond hair and both of her parents have brown hair what does that tell you about the allele for blond hair?
Both of the parents were heterozygous with the blonde hair allele, which is recessive. When there are two parents that are heterozygous, there is a 25% chance their offspring will get two of the recessive alleles. A punnett square can be useful when determining the different phenotypes and genotypes possible in offspring
In order for a child to inherit a recessive trait both parents must be carriers of the recessive gene?
No. A recessive gene can be inherited from one parent, a dominant from another, or two alike dominants. (No such thing as two alike recessive, the gene with the furthest back dominant gene. Say a blonde little girl has a blonde hybrid mother and a brown hybrid father. She ended up getting brown recessive. Since both of her parents were hybrid, she only had a recessive hair color gene from one parent.
How did Apollo end up with blonde hair if neither his mother or his father have blonde hair?
not totally sure, but based off of genetics...both of his parents would have to have a recessive gene for blonde hair, and he was that 25% chance that they would have a blonde haired child.
What happens when an allele is dominate or recessive?
Well, a dominant allele carries dominant traits from parents to offspring. An example of a dominant trait is brown hair and brown eyes because these traits are most likely to show up on a human than a recessive allele. A recessive allele may carry a recessive trait from parents to offspring such as blonde hair and blue eyes, these are uncommon because they are recessive traits.
To have blond hair do both of your genes have to be for blond hair?
not necessarily.ok there are two parents each giving the child one gene. if one gene is recessive and one is dominant the dominant gene will decide the hair color. example the recessive gene is black hair and the dominant gene is blonde the child will most likely have blonde hair because the dominant gene is blonde hair. the dominant gene masks the recessive gene
If a child has blonde hair and both the parents have brown hair what does that tell you about the allele for blonde hair?
It tells you that even though the parents have brown hair, they have a recessive allele for blonde hair also. And even though brown is suppose to be visually dominant, it is not the case at all. Two brown heads can make a blonde or brown, and of course even red haired child. Another way to look at it may be the parents have the following alleles for hair color: (b,b) - (b,b) in which case the dominant allele is Blonde or Brown.
Can a white mother and mixed father have a white and blond baby?
Yes, they can have a baby with blond hair if the mother has the gene that produces blonde hair (recessive) and also if the father has the same gene. It would be best if they both had blonde hair, but two people with brown hair can still have a blonde haired baby. It all depends on the genes that the parents received from their parents.
Is blond or red hair dominent?
Neither, but blonde is less recessive.
Do blondes have to have blonde parents?
most likely blondes have blonde parents or light brown hair parents
Who are melanin recessive?
Melanin recessive are those with light skin, light eyes, and light hair.
If a child has blonde hair and both of her parents have brown hair what does that tell you about the allele for blonde hair?
It means the freckle trait is recessive. For example, if the allel for freckles is 'f', then the parents must have 'Ff' and both sent a 'f' to the offspring.If one sent a 'F', then the child would have freckles.OMG, gotta tell my science teacher about that, cuz we're learning about traits now and I'm shocked that I knew that!
Are there more blondes or brunettes in the world?
Blonde is a recessive trait. There are more brunettes.
