Heart chambers — roles?
Atria receive, ventricles pump blood.
Alleles — dominant vs recessive?
Dominant masks recessive; expressed in heterozygotes.
Right Atrium — role?
Receives deoxygenated blood from body.
Left Atrium — role?
Receives oxygenated blood from lungs.
Right Ventricle — function?
Pumps blood to lungs for oxygenation.
Left Ventricle — role?
Pumps oxygenated blood to body.
Dominant allele — definition?
Expresses trait over recessive allele.
Recessive allele — definition?
Masked by dominant, shown in homozygous recessive.
Heart chambers — synchronized roles?
Work sequentially for blood flow, oxygenation, and circulation.
