Haploid cells
Are cells resulting from mitosis genetically identical or different to the parent cell?
Genetically identical
Are cells resulting from meiosis genetically identical or different to the parent cell?
Different
Define allele
Different forms of the same gene
Define chromosome
Structure that carries all the genetic information for an organism
Define heterozygous
having two different alleles (ex: Tt)
Define homozygous
having two of the same alleles (ex: TT or tt)
Define genotype
genetic make up for a particular trait
Define phenotype
physical expression of a particular trait
Define diploid
when a cell contains two complete sets of chromosomes
Define haploid
when a cell contains only one complete set of chromosomes
Define genetics
the study of heredity and how traits are inherited
