Science Genetics

Gene a part of DNA found on a chromosome, it is responsible for inherited traits that make one person different from another, and they come in pairs
genetics the study of heredity
inheritance passing of traits from one generation to another
allele one gene pair
chromosome a structure found in the nucleus that contain genetic information
phenotype how organisms physically appear
genotype set of genes carried by the organism
dominant always expressed in the phenotype and represented by capital letters
recessive represented by lower case letters and is only expressed in the phenotype when its alleles are identical
homozygous they have same size alleles
hererozygous they have different size alleles
purebred homozygous
hybrid heterozygous
acquired traits traits that you are not born with
pedigree chart that shows and inheritance pattern of a family through multiple generations
incomplete dominance both alleles contribute to the phenotype and it results in a blended or mixed phenotype
multiple alleles when there are more than 2 versions of a trait in a population
co-dominance when both alleles are expressed in a heterozygous genotype
polygenetic trait when one trait is controlled by more than one gene
sex linked traits originate from genes found on sex chromosomes
