The parents are both recessive (Ss) for sickle cell anemia.
The parents are both recessive (Ss) for sickle cell anemia.
X*X and XY
Depends on the disease- dominant gene or recessive gene- and the genotypes of the parents.
People receive a total of 46 genotypes from their parents.
the genotypes of their parents
The parents have normal genotypes, because Klinefelter's syndrome is not inherited.
The letters on the outside are the genotypes of two parents. Inside are the possible genotypes of possible offspring of the two
The parents can pass on only the alleles of their genotypes to their offspring. Therefore, the offspring genotypes and phenotypes are dependent solely upon the alleles inherited from the parents.
25% will have the disease if both parents carry the gene. 50% will be carriers. 25% will be neither.
A Punnett square is used to lay out the possible genotypes of offspring based on the genotypes of the parents being bred. From this, the probabilities of certain phenotypes and genotypes can be determined.
That depends entirely on the genotypes of the parents.
