Genetics
Question | Answer |
---|---|
Dominant | the characteristic encoded for is always expressed |
Recessive | the characteristic encoded for is expressed only in the absence of a dominant |
Homozygous | having a gene with two of the same alleles |
Heterzygous | having a gene with two different alleles |
Phenotype | a characteristic encoded for by genes |
Genotype | allelic content of a gene pair |
Monohybrid Cross | considers one gene pair per parent |
Dihybrid Crosss | considers two gene pairs per parent |
Be able to calculate the expected genotypic and phenotypic rations for monohybrid crosses involving complete or incomplete dominance | Complete Phenotypic ratio: HD, HETER, HR Complete Genotypic ratio: D, R Incomplete Phenotypic ratio: HD(1), HETER, HD(2) Incomplete Genotypic ratio: HD(1), HETER,, HD(2) |
