front 1 gene | back 1 contains the genetic information |
front 2 allele | back 2 two or more different forms of a gene that code for different variations of the same trait |
front 3 gene locus | back 3 the specific location of a gene on a chromosome |
front 4 chromosome | back 4 a DNA molecule with proteins |
front 5 true breeding | back 5 offspring of their crosses are all like the parents in one or more traits |
front 6 homozygous | back 6 same identical alleles |
front 7 heterozygous | back 7 different alleles |
front 8 dominant allele | back 8 masks the presence of the homozygous allele |
front 9 recessive allele | back 9 only expressed when in homozygous state |
front 10 incomplete dominance | back 10 two alleles that when heterozygous create an blended phenotype |
front 11 codominance | back 11 two alleles neither of which dominates the other, heterozygous exhibits both forms of the trait |
front 12 multiple traits | back 12 a gene that has more than two different alleles for a trait within a population |
front 13 genotype | back 13 description of an allele |
front 14 phenotype | back 14 observable traits of an individual |
front 15 probabilty | back 15 likelihood of an event |
front 16 hybrid | back 16 a heterozygote for a specific trait |
front 17 monohybrid cross | back 17 a cross between individuals that are heterozygous for a single trait |
front 18 dihybrid cross | back 18 a cross between individuals that are heterozygous for two traits |
front 19 testcross | back 19 a cross between an individual with a dominant phenotype but unknown genotype against a homozygous recessive |
front 20 law of segraegation | back 20 individualinherits pairs of genes for traits and that the two genes segregate into separate gametes during meiosis |
