genetics Flashcards

1261794422	alleles	Different forms of a gene
1261794423	dominant	Describes a trait that covers over, or dominates, another form of that trait.
1261794424	genetics	Scientific study of heredity
1261794425	genome	All the genetic information in an organism; all of an organism's chromosomes.
1261794426	genotype	Genetic makeup of an organism
1261794427	heredity	Passing of traits from parents to offspring
1261794428	heterozygous	An organism that has two different alleles for a trait
1261794429	incomplete dominance	A pattern of inheritance in which two alleles, inherited from the parents, are neither dominant nor recessive. The resulting offspring have a phenotype that is a blending of the parental traits.
1261794430	co- dominance	When both alleles in the heterozygote are expressed in the phenotype. Written with capitol letters with superscript
1261794431	pedigree	A diagram that shows the occurrence of a genetic trait in several generations of a family
1261794432	phenotype	An organism's physical appearance, or visible traits.
1261794433	polygenic inheritance	of many inheritance
1261794434	probability	A number that describes how likely it is that an event will occur
1261794435	recessive	An allele that is masked when a dominant allele is present
1261794436	sex-linked gene	gene located on the X or Y chromosome
1261794437	antigen	A protein that, when introduced in the blood, triggers the production of an antibody
1261794438	antibody,	noun, a blood protein produced in response to and counterattacking a specific antigen
1261794439	segregation of alleles	partner genes on homologous chromosomes are separated and end up in different sex cells
1261794440	Independent assortment	Independent segregation of genes during the formation of gametes
1261794441	duplicated chromosomes	a chromosome that is composed of two sister chromatids held together in a centromere
