Can a child have different genotype from his parents?

The child can only pass on an A gene to his offspring. If one parent contributes and A gene and the other contributes an O gene, the child will have A blood type, but, like his parents, he’ll also have both A and O genes that he may pass along to his children.

Can genotype change from AA to as?

Can my genotype change from AA to AS? – Quora. No change by any means is possible as they are inherited from the parents. The haemoglobin genotypes AA, AS, AC, or SS etc are obtained by inheritance and will stay lifelong.

Can a genotype be AA?

Types of Genotype The genotypes in humans are AA, AS, AC, SS. They refer to the hemoglobin gene constituents on the red blood cells.

Can parents have the same genotype?

One allele for every gene in an organism is inherited from each of that organism’s parents. In some cases, both parents provide the same allele of a given gene, and the offspring is referred to as homozygous (“homo” meaning “same”) for that allele.

How do I know my genotype?

Sometimes a genetic test will give you your genotype. Sometimes you just need a bit of genetic luck in your family tree to figure it out. And sometimes you can tell the two genotypes apart just by looking at someone. An obvious way to figure out you genotype is to have a genetic test done.

Can brothers have the same genotype?

Because of recombination, siblings only share about 50 percent of the same DNA, on average, Dennis says. So while biological siblings have the same family tree, their genetic code might be different in at least one of the areas looked at in a given test. That’s true even for fraternal twins.

Can siblings have different genotypes?

X and Y chromosome differences mean that brothers and sisters can never have identical genotypes. However, brothers have the same DNA on their Y chromosomes.

Can genotype AA and AA produce as?

Can AA and AA genotype give birth to AS? – Quora. No, one or both of the parents would have to have an AS or SS genotype. SCD denotes all genotypes containing at least one sickle gene, in which HbS makes up at least half the hemoglobin present.

Can as genotype marry as genotype?

However, AS and AS should not marry because there is every chance of having a child with Sickle Cell Disease, while AS and SS shouldn’t think of marrying.
