LHS Genetics Bio I

This is a stack of common genetics terms that you need to know for your test.

Heterozygous the type of genetic combination that occurs when an organism has two different alleles for one trait; an example is Bb
Haploid a cell, such as a gamete, that has only one set of chromosomes; represented by the symbol "n"
Diploid a cell that has two sets of chromosomes; is represented by the symbol "2n"
Complete Dominance an inheritance relationship in which one allele is completely dominant over the other; both BB and Bb will express the dominant phenotype
Homozygous the type of genetic combination that occurs when an organism possesses two identical alleles for one trait; when written, an example would be BB or bb
Monohybrid Cross a type of punnett square that examines one trait
Incomplete Dominance a type of inheritance in which F1 (first filial generation) hybrids have a phenotype that looks like a "blend" between the parental phenotypes
Phenotype a physical trait of an organism, such as eye color, that results from its genetic makeup
Genotype the combination of dominant and recessive genes (alleles) in an organism's cells
