12 Allele Recessive Phenotype Offspring Homozygous Incomplete dominance
Two alleles blend their characteristics in a trait. Allele Recessive Phenotype Offspring Homozygous Incomplete dominance Codominance Dominant Gametes Genotype Proportion Genetic variation Heterozygous Complete dominance Sex-linked trait Multiple alleles Polygenic traits

13 Allele Recessive Phenotype Offspring Homozygous Incomplete dominance
One allele completely masks the other Allele Recessive Phenotype Offspring Homozygous Incomplete dominance Codominance Dominant Gametes Genotype Proportion Genetic variation Heterozygous Complete dominance Sex-linked gene Multiple alleles Polygenic traits

14 Allele Recessive Phenotype Offspring Homozygous Incomplete dominance
Both alleles are equally dominant – both are expressed. Allele Recessive Phenotype Offspring Homozygous Incomplete dominance Codominance Dominant Gametes Genotype Proportion Genetic variation Heterozygous Complete dominance Sex-linked gene Multiple alleles Polygenic traits

15 Allele Recessive Phenotype Offspring Homozygous Incomplete dominance
More than two alleles can code for a gene. Ex. Human blood type is controlled by three alleles: IA , IB and i. Allele Recessive Phenotype Offspring Homozygous Incomplete dominance Codominance Dominant Gametes Genotype Proportion Genetic variation Heterozygous Complete dominance Sex-linked gene Multiple alleles Polygenic traits

16 Allele Recessive Phenotype Offspring Homozygous Incomplete dominance
Caused by genes found on the X chromosome. Fewer females are afflicted because they have two X chromosomes and the other is usually normal. Ex. Colorblindness, Hemophilia (inability to clot blood) – both are recessive. Allele Recessive Phenotype Offspring Homozygous Incomplete dominance Codominance Dominant Gametes Genotype Proportion Genetic variation Heterozygous Complete dominance Sex-linked traits Multiple alleles Polygenic traits

17 Allele Recessive Phenotype Offspring Homozygous Incomplete dominance
More than two genes control a trait. This trait often show a wide range of phenotypes. Ex. The variety of skin color, in humans comes about partly because more than four different genes probably control this trait.

18 Show me (use letter “T” & “t”)
Recessive allele Homozygous recessive genotype Heterozygous genotype Two parents that are both heterozygous for a trait Dominant allele Homozygous dominant genotype One parent that is heterozygous and the other that is homozygous recessive tt Tt Tt x Tt T If time TT Tt x tt

19 Show me (using pieces in baggie)
What the gametes would be if a parent was AABB What the gametes would be if a parent was Aabb What the gametes would be if a parent was AaBb. AB, AB, Ab, AB Ab, Ab, ab, aB If time Ab, Ab, aB, ab

20 Predict their parents' genotypes

21 Results in 1/2 black pups and 1/2 blonde pups
