If an AC genotype man and an AS genotype woman marry, each of their children has a 25% chance of being born with a sickle cell disease (SS genotype), a 50% chance of being a carrier like their parents (AS genotype), and a 25% chance of having a normal genotype (AA).
Marriage has nothing do to with genotypes. Marriage, a blow to the head, oranges, and playing golf are all the same in that they don't affect genotypes in any way.Now...perhaps you meant to ask about the offspring of a man and a woman with such genotypes. Traditionally marriage precedes the birth of a child, but not always, so call it what it is: sex. So the question is if a man (genotype AS) has sex with a woman (genotype AS), will the baby be at risk for sickle cell anemia. There is a 25% chance that the child will have the disease (genotype SS).Again, to drive the point home, the proper wording of this question should not include "can" even if we get rid of the marriage nonsense. Ability here is not an issue. We also can't answer if they should have a baby, because that is entirely their decision even if they know the risks.
Individuals with the Ss genotype are resistant to malaria because the presence of the sickle cell trait (S gene) alters the shape of red blood cells, making it difficult for the malaria parasite to infect and replicate within the cells. This in turn reduces the severity of malaria symptoms and provides a natural defense mechanism against the disease.
If both parents have sickle cell trait, they each carry one normal allele (A) and one sickle cell allele (S). The possible genotypes for their children are AA (normal), AS (carrier), and SS (sickle cell disease), with a probability of 25% for each genotype. Therefore, the chance of having three children who are homozygous for normal red blood cells (AA) is ( (0.25)^3 ), which equals 1/64, or about 1.56%.
Let's say that the squarepants shape is dominant over the circlepants shape. I'm going to say that the dominant form of the gene is S. If he is heterozygous, then it would be Ss.
No, an AAA and SS combination can only produce an Aa genotype. The offspring will inherit one allele from each parent, resulting in a heterozygous genotype. For an AAA genotype to be produced, both parents must have the same alleles for the specific gene.
It is not possible. NO
im not sure u guess plz thx man
There are three outcomes if a person with an AS genotype marries a person with another AS genotype. The offspring has a 50 percent chance of inheriting the AS genotype, and a 25% chance of having a child with an AA or SS genotype. Most couples who share the AS genotype choose not to procreate.
no they can only have children with as as as as
You cannot do a cross to determine the genotypes of individuals because there is only one gene here. Genotype consists of the entire genetic makeup of the individual, which cannot be determined by a single gene. Only the alleles S or s is used to express this particular gene. If you're looking for a monohybrid cross between Ss and Ss, while separately wanting a result between ss and ss, then the answers are as follows: Ss x Ss 25% SS 50% Ss 25% ss ss x ss = 100% ss
First child will always prevail from being SS. Some even have AA, but most of the time. Its AS.

No, AA and SS cannot give birth to AA offspring. In this scenario, there would be a 50% chance of producing AS offspring (heterozygous) and a 50% chance of producing SS offspring (homozygous recessive).
25% The four possibilities are aa as as ss
The blood test is called a hemoglobin electrophoresis test, which is used to determine an individual's hemoglobin genotype. A result of 'AA' indicates normal hemoglobin, 'AS' indicates sickle cell trait (carrier), and 'SS' indicates sickle cell disease.
"Ss" refers to a genotype, representing the genetic makeup of an individual for a specific trait. The genotype "Ss" indicates that the individual carries one dominant allele (S) and one recessive allele (s) for that particular trait. The phenotype, on the other hand, is the observable physical or physiological expression of the genotype, which may vary depending on the dominance relationships between the alleles.
