Genetics explores inheritance patterns from "summary" of The Biology Book by DK
Genetics delves into the intricate world of inheritance, seeking to uncover the patterns that dictate the transmission of traits from one generation to the next. At its core, genetics is the study of genes, the units of heredity that carry the instructions for building and maintaining an organism. These genes are passed down from parents to offspring, shaping everything from physical characteristics to predispositions for certain diseases. Through the study of genetics, scientists have been able to unravel the mechanisms by which traits are inherited. One of the fundamental principles of genetics is the concept of dominant and recessive alleles. Dominant alleles are those that are expressed in an organism's phenotype, or physical appearance, while recessive alleles are masked by dominant ones. This interplay between dominant and recessive alleles gives rise to the diversity of traits observed in populations. Another important aspect of genetics is the concept of genetic variation. Genetic variation refers to the differences in DNA sequences amo...
