Nov 30, 1998 · The traits of a living thing depend on the complex mixture of interacting components inside it. Proteins do much of the chemical work inside cells, so they largely determine what those traits are.

Traits are determined by an individual's genotype, the summation of the genes in our DNA. A gene is a portion of a chromosome. A chromosome is composed of DNA and contains the genetic material for an organism. Humans have twenty-three pairs of chromosomes. Twenty-two of the pairs are called autosomes. Autosomes are typically very similar in males a...
How are traits passed from one generation to the next? This happens when gametes unite. When an egg is fertilized by a sperm, for each chromosome pair, we receive one chromosomefrom our father and one from our mother. For a particular trait, we receive what is known as an allelefrom our father and one allele from our mother. An allele is a differen...
When alleles are expressed via simple dominant versus recessive traits, the specific alleles inherited determine how the phenotype is expressed. When an individual has two dominant alleles, the phenotype is the dominant trait. Likewise, when an individual has one dominant allele and one recessive allele, the phenotype is still the dominant trait. W...
A longer second toe and attached earlobes are often cited as examples of a "weird trait" that follows the two dominant/recessive alleles forms of one gene inheritance. Again, however, evidence suggests that both attached earlobe and longer second toe inheritance are quite complex.

Dec 20, 2023 · These traits are determined by specific sections of DNA called genes, which are located on chromosomes. Humans have 23 pairs of chromosomes, with one set inherited from each parent. Each chromosome contains hundreds to thousands of genes, which determine various traits such as eye color, height, and hair texture. Alleles and Inheritance
Dec 20, 2023 · These traits are determined by specific sequences of DNA, known as genes, which are located on chromosomes within the cells of an organism. Human beings have approximately 20,000-25,000 genes, and each gene carries the instructions for one or more specific traits.
Inheritance is the passing of traits from parents to offspring. Our modern understanding of inheritance comes from a set of principles proposed by Austrian monk and researcher Gregor Mendel in 1865.
Mendel studied the inheritance of a number of well-defined traits, such as seed color, and was able to deduce general rules for their transmission. In all cases, he could correctly interpret the observed patterns of inheritance by assuming that each trait is determined by a pair of inherited factors, which are now called genes.

DNA contains the genes that serve as the blueprint for making proteins. Each protein has a unique sequence of amino acids. Since different amino acids have different chemistries (such as acidic vs. basic, or polar vs. nonpolar), the order of amino acids in a protein determines how the protein folds, thereby determining the shape and function of the protein.
