Chromosomal Theory of Inheritance

Family theories have been founded on research that cannot discriminate genetic and environmental influences and, consequently, most theories do not have highly developed models of gene—environment interplay in families. Behavioral genetic approaches, which can identify gene—environment interplay, have typically not been driven by family theories and have lacked adequate measurement of family processes. In this article, the authors describe behavioral genetic mechanisms and methods using representative examples of research on family processes, highlighting the advantages of an integrated approach. New directions in research and theory driven by an integrated approach are discussed. In the s, however, researchers looking at samples of family members that varied in degree of genetic relatedness e. If family environment is so influential, they asked, then why do siblings end up so different from each other?

A chromosome is a long DNA molecule with part or all of the genetic material of an organism. Most eukaryotic chromosomes include packaging proteins called histones which, aided by chaperone proteins , bind to and condense the DNA molecule to maintain its integrity. Chromosomes are normally visible under a light microscope only during the metaphase of cell division where all chromosomes are aligned in the center of the cell in their condensed form. The joined copies are now called sister chromatids. During metaphase the X-shaped structure is called a metaphase chromosome, which is highly condensed and thus easiest to distinguish and study. Chromosomal recombination during meiosis and subsequent sexual reproduction play a significant role in genetic diversity.

Genetics is a branch of biology concerned with the study of genes , genetic variation , and heredity in organisms. Though heredity had been observed for millennia, Gregor Mendel , Moravian scientist and Augustinian friar working in the 19th century in Brno , was the first to study genetics scientifically. Mendel studied "trait inheritance", patterns in the way traits are handed down from parents to offspring. He observed that organisms pea plants inherit traits by way of discrete "units of inheritance". This term, still used today, is a somewhat ambiguous definition of what is referred to as a gene.

    It was scarcely rational to reject all theories assuming the germ-cell to contain a number of definite substances that are the agents through which heredity takes.
