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.
The predicted ratio of offspring in a mating of AAA and AAA would be 100% AAA. Since both parents have the same genotype, all of their offspring will inherit the same genotype.
If the parents both have the genotype Aa, their children could have the genotypes AA, Aa, or aa. The possible phenotypes for their children would be individuals with type A blood (AA or Aa genotype) or type O blood (aa genotype).
Only one; A. At least concerning this one trait.
This is a homogenous state of the gene coding for antigen A (consequently blood group A) on the plasma membrane of the erythrocytes.There are three genes that have been isolated as being responsible for blood groups i.e A,B,O.A and B codes for the presence of the respective antigen on the R.B.C while O codes for the absence of both antigen A&B.Gene A and B are co-dominant and thus an individual with genotype AB has blood group AB because both genes express themselves phenotypically.Genotype AO will still be phenotypically expressed as blood group A just like AA.
The answer is genotype
50% AA and 50% Aa
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.
The predicted ratio of offspring in a mating of AAA and AAA would be 100% AAA. Since both parents have the same genotype, all of their offspring will inherit the same genotype.
no they can only have children with as as as as
homozygous? homozygous? homozygous dominant
For the two given parents: 1 offspring will have the homozygous genotype: YY 1 offspring will have the homozygous genotype: yy 2 offspring will have the heterozygous genotype: Yy
The offspring's genotype will be AA. Both parents are homozygous dominant, AA, having only dominant alleles to pass on to their offspring. So each parent can pass on only the dominant allele (A) to its offspring. So the offspring will also be homozygous dominant, AA.
offspring will be produced in following AA :Aa:aa and is in the ratio of 1:2:1 so the probabiltiy is 50%
The genotypic ratio for two parents with the genotypes AAA and AAA is 1:0. This means that all offspring will have the genotype AAA.
Yes, in most societies. Genotyping is generally not done before marriage, so genotypes of the couple are unknown.
If the parents both have the genotype Aa, their children could have the genotypes AA, Aa, or aa. The possible phenotypes for their children would be individuals with type A blood (AA or Aa genotype) or type O blood (aa genotype).
