From Mendel’s pea plants to today’s genome mapping, our understanding of genetics has transformed how we see heredity, traits, and evolution. DNA’s code, once mysterious, now reveals a complex ...

In Mendelian inheritance patterns, you receive one version of a gene, called an allele, from each parent. These alleles can be dominant or recessive. Non-Mendelian genetics don’t completely follow ...

Genetic disorders can occur due to mutations in one gene (monogenic), multiple genes (multifactorial inheritance), and mutation in one or more chromosomes. Point mutations are where one nucleotide in ...
