Review

    • Allele the different forms of a gene, for example pea color has alleles for yellow and for green.
    • Chromatid one-half of the replicated chromosome. heterozygous chromosomes, chromatids
    • Diploid haveing both pairs of homologous chromosomes (n=46 in humans)
    • Dominant gene-type (allele) which is expressed in combination with recessive gene
    • Genotype genetic makeup
    • Haploid haveing one of each pair of homologous chromosomes (n=23 in humans)
    • Heterozygous having both kinds of gene for a trait
    • Homologous Chromosomes the pair of "identical" chromosomes, from the two parents heterozygous chromosomes, chromatids
    • Homozygous having only one kind of gene for a trait
    • Phenotype physical appearance (of a trait)
    • Recessive gene-type (allele) which is not expressed in combination with dominant gene
    • Mitosis
