dominant/recessive - Answer one phenotype completely masks the other
incomplete dominance - Answer blending in the heterozygous
co-dominance - Answer both phenotypes are shown in the heterozygous
lethal alleles - Answer alleles that cause early death
look for 2:1 ratio
sex-linkage - Answer will show different ratios between the normal cross and the reciprocal
cross
genetic linkage - Answer occurs between genes that lie so close together on a chromosome
that their alleles are unable to assort independently
produces more parental phenotypes than non-parental phenotypes
recombination - Answer refers to the process of recombining genes to produce new gene
combinations that differ from those of either parent
produces genetic variation in organisms
occurs as a result of separation of genes during meiosis, the random uniting of these genes
during fertilization
