What does monohybrid inheritance mean?
The study of the inheritance of alleles for one gene
What does dihybrid inheritance mean?
The study of the inheritance of alleles for two genes
What does gene mean?
A sequence of DNA bases at a specific locus on a chromosome that codes for one polypeptide
What does allele mean?
An alternative form of a gene, found at the same locus (on another chromosome) but may produce a different phenotype
What does haploid mean?
One set of chromosomes
What does diploid mean?
Two sets of chromosomes
What does polyploid mean?
More than 2 sets of chromosomes
What does genome mean?
The complete set of genes in a cell
What does genotype mean?
The genetic constitution of an organism
What does phenotype mean?
The observable characteristics of an organism. A product of the interactions between the genotype and the environment
What does homozygous mean?
An organism that had the same alleles for a particular gene on each homologous chromosome
What does heterozygous mean?
An organism that has 2 different alleles for the same gene
What does dominant mean?
When one allele masks or prevents the expression of another
What does recessive mean?
When one allele is masked or prevented from expression by another
