to the right ventricle. The ventricle contracts, pushing blood to the lungs via pulmonary arteries. In the lungs, blood absorbs oxygen and releases carbon dioxide. Oxygenated blood returns to the left atrium via pulmonary veins. Blood flows into the left ventricle
n disorders are inherited: Autosomal Recessive: Both alleles must be recessive; carriers are unaffected. Example: Cystic fibrosis. Autosomal Dominant: One dominant allele causes the disorder. Example: Huntington's disease. X-
of Human Chromosomes Gene Distribution Human chromosomes contain between approximately 200 to 2,000 genes. The distribution is uneven; chromosome 1 is gene-rich, whereas chromosome 21 has fewer genes despite being small. Function of Chromosomal
while others participate in more complex interactions. Common Inheritance Patterns in Humans To grasp human heredity fully, it’s important to recognize the typical inheritance patterns: Autosomal Dominant: Only one copy of the mutant
