In humans Attached earlobes (A) is dominant to unattached earlobes (a). Write all three possible genotypes and phenotypes below.

genotype Aa AA aa

Phenotype unattached earlobes, attached ear lobes

Explanation: genotype will be the combination of the genes. you have dominant (AA) recessive (aa) and heterozygous (Aa) the phenotype will be the expression from the genotype so for both dominant and heterozygous the phenotype is attached earlobes and for recessive the phenotype is unattached earlobes

blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. as the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated.
