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.
Is it possible for two parents with brown hair to have an offspring with blonde hair?
If two blonde haired people have a child the child will be blonde as everybody has two hair genes (one from each parent) and you pass one of your genes to your child, to be blonde you have to have two blonde haired genes and as you can only pass blonde genes to your child they will certainly be blonde.Source(s):GCSE science lessons Hi I am sorry to rain on your party but i believe you are incorrect. The reason why is because you can carry a trait but if you are an owner of trait then you have that trait plus others. For example my aunt has blonde hair and her hubby has blonde hair that went to dirty blonde to brown naturally. However, they have a red-head. How is this possible? Doesn't heredity have rules? I am so confussed.
Is blonde hair recessive or dominant?
Recessive gene of X chromosome. more common in men as they have only one x chromosome but in female there are 2 X chromosome. If one of X chromosome in female has this recessive gene, they become a carrier. If both the X chromosome in female has this gene, they show baldness
Can a baby come out blonde if you are brunette?
Yes, it is possible for a baby to be born with blonde hair even if both parents have brunette hair. Hair color is determined by a combination of genes from both parents, so there can be variations in hair color among offspring.
Can two blonde parents have a dark haired child?
Yes, two blonde parents can have a dark-haired child if they both carry a recessive gene for dark hair. The dark hair trait could be passed down from previous generations. Hair color is determined by a combination of parental genes, so genetic variability allows for different combinations of traits in offspring.
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!
If both parents have blonde hair why can their children have brown red or very dark hair?
Children can inherit hair color from a combination of genes contributed by both parents, including recessive and dominant traits. Even if both parents have blonde hair, they may carry hidden genes for darker hair colors, which can be passed down to their offspring. Additionally, genetic variation and mutations can also lead to unexpected hair colors in children. Thus, the diversity in hair color can result from the complex interplay of multiple genes.
Can a child have blonde hair if the mother father both have brown hair?
It depends on whether or not blond hair is a dominant gene or a recessive gene. For example: B= brown, b= blonde (in this case brown is dominant). You may have BB or Bb and your partner BB or Bb if one of you is heterozygous (BB) then no you can't but if both of you are homozygous dominant then yes there is a 25% chance of a blonde child. In this case both parents could be brown haired and the child blond.
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.
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.
