11 Curriculum Framework 3. The pattern of inheritance (monohybrid, dihybrid, sex-linked, and genes linked on the same homologous chromosome) can often be predicted from data that gives the parent genotype/ phenotype and/or the offspring phenotypes/genotypes.
12 Mendelian Genetics Law of Dominance - if the two alleles at a locus differ, then one (the dominant allele) determines the organism s appearance, and the other (the recessive allele) has no noticeable effect on appearance 2
13 Human Traits with simple dominance: Widows peak Handedness Free earlobes Cleft Chin Dimples Freckles PTC testing Polydactyly Bent little finger Nearsightedness Mid-digit hair 3
14 Dominant does not mean numerous Frequency of Dominant Alleles Dominant alleles are not necessarily more common in populations than recessive alleles For example, one baby out of 400 in the United States is born with extra fingers or toes
15 In humans, alleles for dark hair are genetically dominant, while alleles for light hair are recessive. Which of the following statements is/are most likely to be correct? a. Dark hair alleles are more common than light hair alleles in all areas of Europe. b. Dark hair alleles are more common than light hair alleles in southern Europe but not in northern Europe. c. Dark hair alleles are equally common in all parts of Europe. d. Dark hair is dominant to light hair in southern Europe but recessive to light hair in northern Europe.
16 Curriculum Framework b. Segregation and independent assortment of chromosomes result in genetic variation.. Segregation and independent assortment can be applied to genes that are on different chromosomes. 2. Genes that are adjacent and close to each other on the same chromosome tend to move as a unit; the probability that they will segregate as a unit is a function of the distance between them.
17 Mendelian Genetics Law of segregation: the two alleles for a heritable character separate (segregate) during gamete formation and end up in different gametes 7
