COMPLETE SOLUTIONS VERIFIED RATED 100%


gene


sequence of DNA that encodes a specific protein


allele


one of two or more alternative forms of a gene

-might be identical or different


Gregor Mendel


uncovered basic laws of inheritance


true-breeding


always producing offspring identical to the parent for one or more traits; homozygous


dominant allele


allele that is expressed whenever it is present


recessive allele


allele whose expression is masked if a dominant allele is present

, genotype


an individual's combination of alleles for a particular gene (YY or Yy or yy)


homozygous dominant


type of genotype, having 2 dominant alleles for a gene (YY)


heterozygous


type of genotype, having one dominant and one recessive allele (Yy)


homozygous recessive


type of genotype, having 2 recessive alleles (yy)


phenotype


observable characteristic of an organism (green or blue)


wild-type


the most common phenotype, genotype, or allele


mutant


a genotype, phenotype, or allele is a variant that arises wen a gene undergoes mutation.


P generation


(parental generation) - the first generation (true-breeding) in a genetic cross


F1 generation


(first filial generation) - the offspring of the P generation in a genetic cross


F2 generation
