Quantitative traits vary in characteristics and are influenced by two or more genes and environmental factors. They are often continuous and difficult to predict, and are documented using numbers and percentages. Polygenic inheritance and quantitative trait locus are involved in their formation, and they appear in nearly all organisms. Examples include height, intelligence quotient, and […]
Trait anxiety is a personality disorder where people perceive situations as more dangerous than they are, leading to excessive fear and a feeling of doom. It can cause panic attacks, phobias, and other mental conditions, and is triggered by a physiological response that causes adrenaline to be released. Genetics and environmental factors can play a […]
Dominant traits occur when one copy of a gene overrides another, while recessive traits only appear if both copies of the gene are inherited. Gregor Mendel’s research on peas in the 19th century popularized the concept. Eye color is determined by genes in different alleles that interact with each other to create various colors. A […]
Recessive traits require two copies of the gene to manifest, while dominant traits only require one. Gregor Mendel first proposed the concept of dominant and recessive traits in genetics. Inheritance of genetic material from both parents creates homozygous or heterozygous alleles, with one allele remaining inactive in heterozygous individuals, representing a recessive trait. Mendel’s work […]
