Question | Answer |
selective breeding | the intentional mating of two animals in an attempt to produce offspring with desirable characteristics or for the elimination of a trait |
inbreeding | the mating of closely related individuals, as cousins, sire-daughter, brother-sister, or self-fertilized plants, which tends to increase the number of individuals that are homozygous for a trait and therefore increases the appearance of recessive traits. |
hybridization | to breed or cause the production of (a hybrid). |
cloning | the process of producing a clone |
genetic engineering | the development and application of scientific methods, procedures, and technologies that permit direct manipulation of genetic material in order to alter the hereditary traits of a cell, organism, or population. |
DNA fingerprinting | the use of a DNA probe for the identification of an individual, as for the matching of genes from a forensic sample with those of a criminal suspect. |
gene | the basic physical unit of heredity; a linear sequence of nucleotides along a segment of DNA that provides the coded instructions for synthesis of RNA, which, when translated into protein, leads to the expression of hereditary character. |
chromosome | any of several threadlike bodies, consisting of chromatin, that carry the genes in a linear order: the human species has 23 pairs, designated 1 to 22 in order of decreasing size and X and Y for the female and male sex chromosomes respectively |
DNA | deoxyribonucleic acid/ the set of nongenetic traits, qualities, or features that characterize a person or thing |
nucleotide | any of a group of molecules that, when linked together, form the building blocks of DNA |
nitrogen bases (A, T, C, G) | Adenine, Thymine, Cytosine, Guanine, |
double helix | the spiral arrangement of the two complementary strands of DNA. |
DNA replication | DNA replication is the process of producing two identical replicas from one original DNA molecule |
mutation | a sudden departure from the parent type in one or more heritable characteristics, caused by a change in a gene or a chromosome. |
sex chromosome | a chromosome, differing in shape or function from other chromosomes, that determines the sex of an individual |
