Principle of Independent Assortment
states that genes for different traits can segregate independently during the formation of gametes
neither allele is truly dominant. A heterozygote's phenotype is a mixture of both traits (RRxR'R'=RR')
both alleles are dominant. there's a presentation of both traits in a heterozygote (RRxWW=RW or red and white spots)
there are more than two alleles available for the trait. ex: coat color in rabbits (refer to notes)
traits are controlled by more than one gene. ex: skin, hair, eye color, height weight, etc. traits with lots of variation.
when homologs (paired chromosomes) fail to separate during meiosis. daughter cells have too many or too few chromosomes
sex linked traits
traits that are dominant or recessive depending on gender, disorder pertinent to gender, ie females cant be colorblind..traits can only be carried or present on X or female gene
an association between genes in sex chromosomes that makes some characteristics appear more frequently in one sex than in the other
