Aperson with a phenotype of hbss has sickle cell disease. a person with a phenotype of hbas allele carries the sickle cell trait. a person with a phenotype of hbaa does not have sickle cell disease and does not carry the trait. the punnett square shows the phenotype of two people carrying the sickle cell trait. hb a s a aa as s as ss what are the chances that their offspring will have sickle cell anemia? 0% 25% 50% 100%

A person with a phenotype of HbSS has sickle cell disease. A person with a phenotype of HbAS allele carries the sickle cell trait. A person with a phenotype of HbAA does not have sickle cell disease and does not carry the trait. The Punnett square in the image shows the resulting progeny after a cross between the two individuals of the genotype, HbAS, who are carrying the sickle cell gene. The probability of offspring getting sickle cell disease turns out to be, 25%.

his research revealed two genetically different groups of prokaryotes, which justified splitting kingdom monera into two kingdoms. the genetic and cellular differences were so great, that these two kingdoms were eventually placed into different domains in the current three-domain system.
