In a karyotype, chromosomes are arranged and numbered by size, from largest to smalles 13 of 30 genotype the combination of genes at a single locus or a number of loci 14 of 30 homozygote a one-locus genotype containing functionally identical genes 15 of 30 heterozygote a one-locus genotype containing functionally different genes 16 of 30 mitosos forms two daughter cells 17 of 30 meiosis forms 4 genetically different gametes 18 of 30 meiosis divides twice 19 of 30 mitosis divides once 20 of 30 types of mutation in dna chromosomal and gene/point 21 of 30 additive gene action / co-dominance performance of heterozygous animals is exactly intermediate of the two homozygous types 22 of 30 complete dominance a form of dominance in which the expression of the heterozygote is identical to the expression of the homozygous dominant genotype 23 of 30 Partial dominance when the effect of one allele is partially but not completely masked by the presence of another allele 24 of 30 over dominance when heterozygotes show more extreme performance than either homozygote 25 of 30 sex-linked genes genes located on the sex chromosomes rather than the autosomes 26 of 30 sex-limited gene trait is only shown in one sex - e.g. milk production 27 of 30 sex influenced genes e.g. sheep breeds males are forned, femals are polled 28 of 30 genomic imprinting effects of a particular genotype or appearance of function depend on which parent contributed each allele 29 of 30 Epistasis presence of an allele on one ocus influences the effect of an allele at a different locus 30 of 30
