incomplete dominance

an inheritance pattern in which neither allele is domiant an the offspring demostrates an intermediate form of the allele from the parents, showing a new form of the trait

Rh factor represents the presence of the rhesus protein on blood.

✔ Rh* blood contains the rhesus protein.

Traits can also be recessive , which means they can be masked.

Alleles are different versions of the same gene in an organism.

Mendelian inheritance states that traits are determined when offspring receive one allele for each trait from one parent each parent.

Traits can be dominant , which means they can be seen and are capable of masking a different trait.

Polygenic inheritance is determined by multiple ⇒ genes located at different loci on different chromosomes.

Genes

The principle of dominance is a Mendelian inheritance pattern. It states traits that are dominant mask the traits that are dominant.

Incomplete dominance is a non-Mendelian inheritance pattern. It states that neither trait is dominant. The traits appear to blend together.

Type AB blood is the universal recipient

Rh+ blood can receive Rh+ or Rh- blood. Rh+✔ Rh- blood can receive Rh- blood.

Rh- blood does not contain the rhesus protein.

Type ✔ O blood is the universal donor.

Blood type is an example of

codominance

Codominance is a non-Mendelian inheritance pattern. It states that both traits are dominant and both appear in the organism. Neither trait is masked.

Blood type is determined by the antigens on the blood cells.

How did the 1898 discovery of blood types affect society? Check all that apply.

New ways to preserve and transport blood for blood transfusions were discovered. Blood transfusion safety was improved. Scientists discovered that elements of blood could be separated by centrifuge. Scientists discovered that plasma could be preserved by freezing.

Polygenic traits follow a non-Mendelian inheritance pattern.
