Mendelian genetics Flashcards
Gene
an inherited factor encoded in DNA that helps determine a characteristic
Allele
One of two or more alternative forms of a gene
Locus
Specific place on a chromosome occupied by an allele
Genotype
Set of alleles possessed by an individual organism
Heterozygote
an individual organism possessing two of the different alleles at a locus
Homozygote
an individual organism possessing two of the same alleles at a locus
Phenotype
The appearance of manifestation of a characteristic
Characteristic
an attribute or feature possessed by an organism
Mendels Law of Segregation
Allele pairs segregate during gamete formation, and randomly unite at fertilization
Mendels Law of Independent Assortment
Alleles of one gene sort into gametes independently of the alleles of another gene
