info@snapandsolve.comExplanation: Genes are segments of DNA located on chromosomes, which are found in the nucleus of cells. Each gene contains the instructions for the development of specific traits by coding for proteins. Chromosomes come in pairs, and humans typically have 23 pairs, with one chromosome of each pair inherited from each parent. This means that each individual inherits two versions of each gene, known as alleles, which can be dominant or recessive. The combination of these alleles determines the expression of a trait. For example, if a trait is determined by a dominant allele, only one copy is needed for the trait to be expressed. Conversely, a recessive trait requires two copies of the recessive allele. Scientific research has shown that this genetic inheritance follows Mendelian principles, which explain how traits are passed from parents to offspring through predictable patterns.
