Fundamentals of Genetics

Heredity Passing of traits from parents to offspring Genetics Branch of biology that studies heredity Monohybrid Cross A cross between individuals that involves one pair of contrasting traits True-Breeding All of the offspring display only one form of a particular trait P Generation First two individuals crossed in a breeding Read more…

Genetics

Allele A variation of a gene’s nucleotide sequence (an alternative form of a gene).

Genetics Key Terms

Alleles alternate forms or varieties of a gene. The alleles for a trait occupy the same locus or position on homologous chromosomes and thus govern the same trait. Amino acid organic molecules that are building block of proteins. There are 20 different kinds of amino acids in living things. Proteins Read more…

Genetics chp 1-3

translational medicine genetic findings are directly translated into new and improved methods of diagnosis and treament The theory of epigenesis states that adult structures in the organism develop de novo from substances present in the egg In many species, there are two representatives of each chromosome. In such species, the Read more…

How does genetics influence our lives? Affect our height, weight, hair color, pigmentation, and susceptibility to diseases and disorders. Contribute to our intelligence and personality. What is a gene? Unit of heredity; coded/noncoded information in DNA. Is genetics a new field of study? Yes and No .People have understood the Read more…

Cell Division Reproduction of a cell; Two “daughter” cells that result are genetically identical to each other and to the original “parent” cell. Chromosomes Structures that contain most of the cell’s DNA. Asexual Reproduction Does not involve fertilization of the egg by sperm; offspring are genetic duplicates of their single Read more…

Genetics Ch. 2 Key Terms

Addition Rule See sum rule. Sum Rule – The probability of an event that can result from two or more equivalent outcomes. The probabilities of the contributing events are added, and their sum is the probability of the event in question. Also known as the addition rule. Anagenesis Phylogenetic evolution Read more…
