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.

Why is it that two normal parents could have a child with pku?
PKU, phenolketonuria, is a genetic disease caused by a recessive gene. So, a person with one normal and one faulty gene for this characteristic will not have the disease, you have to have two faulty genes to have the disease. If two people who each have one gene for PKU have a child, that child can inherit the gene from each parent and therefore will have two copies, causing the recessive trait to manifest.
What are the chances of inheriting a recessive hair color from your parents?
The chances of inheriting a recessive hair color from your parents depend on their genetic makeup. If both parents carry the recessive gene for a certain hair color, there is a 25 chance that their child will inherit that color.
The inheritance pattern that occurs equally in both sexes and skips generations is?
An example of an inheritance pattern that occurs equally in both sexes and skips generations is autosomal recessive inheritance. This means that for a child to inherit the trait or disorder, both parents must be carriers of the recessive gene. The trait may not appear in every generation due to the need for both parents to be carriers.
How could 2 parents with blood type A and B have a child with the blood type of O?
If both parents are carriers of the recessive O allele, they can pass it on to their child. In this case, their child would inherit one O allele from each parent and have blood type O. This is possible because blood type O is recessive to both blood types A and B.
What genotypes would the parents need to have in order to potentially have a child with cystic fibrosis?
In order to potentially have a child with cystic fibrosis, both parents would need to be carriers of the recessive gene for the condition. This means that both parents would need to have the genotype "Aa" for the child to have a chance of inheriting the condition.
Can a child have blue eyes if both parents eyes are brown and green?
It is possible for a child to have blue eyes if both parents are carriers of the recessive blue eye gene. Blue eyes are a recessive trait, so if both parents carry this gene, there is a chance their child could inherit blue eyes.
If both parents are carriers what will the child be?
When a recessive trait is inherited from both parents, it will be expressed. If the trait is hemophilia, the child will be a hemophiliac.
What happen when both parents Carrie a ressavie of gene?
If both parents carry a recessive gene, there is a 25% chance that their child will inherit two copies of the recessive gene, leading to the expressed trait or condition. There is a 50% chance the child will inherit one copy of the gene and be a carrier like the parents, and a 25% chance the child will not inherit the gene at all. This is based on the principles of Mendelian genetics.
Why is it that two normal parents could have a child with pku?
PKU, phenolketonuria, is a genetic disease caused by a recessive gene. So, a person with one normal and one faulty gene for this characteristic will not have the disease, you have to have two faulty genes to have the disease. If two people who each have one gene for PKU have a child, that child can inherit the gene from each parent and therefore will have two copies, causing the recessive trait to manifest.
Is it at all possible for two o negative parents to produce an a positive offspring?
Yes, it is possible for two O negative parents to have an A positive child if both parents are carriers of the A allele. The child would inherit one A allele from each parent, resulting in the A positive blood type.
What is the probability that each child born to two carriers of a recessive disorder allele will have the disorder?
The child will have the disorder, only if the recessive allele from both the parents is transferred to the child. Therefore, the probability is 1/4.
What are the chances of inheriting a recessive hair color from your parents?
The chances of inheriting a recessive hair color from your parents depend on their genetic makeup. If both parents carry the recessive gene for a certain hair color, there is a 25 chance that their child will inherit that color.
How would a child inherit PKU?
A child inherits PKU if both parents are carriers of the gene mutation that causes the condition. When both parents are carriers, there is a 25% chance with each pregnancy that the child will inherit two copies of the mutated gene and have PKU.
Can two O neg people have an A plus baby?
NO. The alleles that lead to "O-type" blood are recessive to the alleles that lead to "A-type" blood and the child would have to inherit this "A" from one of his/her parents. Given that both parents are "O", there is nobody to inherit the "A" from. (This issue also presents with the exclusive RH- in the parents and RH+ in the child, because RH+ is dominant over the recessive RH-.)
The inheritance pattern that occurs equally in both sexes and skips generations is?
An example of an inheritance pattern that occurs equally in both sexes and skips generations is autosomal recessive inheritance. This means that for a child to inherit the trait or disorder, both parents must be carriers of the recessive gene. The trait may not appear in every generation due to the need for both parents to be carriers.
If an individual expresses a dominant disease will the children always inherit the disease?
Not always. It depends if the individual is a hybrid- meaning they have both the dominant and the recessive gene. They can pass on the recessive gene instead of the dominant one, and assuming the other parents also passes on the recessive gene, the child will not inherit the disease.
How could 2 parents with blood type A and B have a child with the blood type of O?
If both parents are carriers of the recessive O allele, they can pass it on to their child. In this case, their child would inherit one O allele from each parent and have blood type O. This is possible because blood type O is recessive to both blood types A and B.
