Answer the guide question in your notebook. Multiple Alleles Mendel studied just two alleles of his pea genes, but real populations of- ten have multiple alleles of a given gene, In this activity you will learn how to crossed the gene for coat color in rabbits (the C gene) which comes in four color alleles (C, Cch, Ch, c) as shown by the figure De below.

Performance Task: Regular Biology Name: Who Gets the Money? Worksheet O bindgdoaolon0ne Part Two: Co-dominance and Incomplete dominance Now that have been eliminated, lawyers order blood tests to try to prove their claims. The lawyers have also done some research and read that hair texture is inherited. Type A and type B blood are co-dominant over type O. Rh+ blood is dominant over Rh- blood. Hair texture exhibits incomplete dominance. Homozygous dominants (HH) have curly hair. Homozygous recessives (hh) hawe straight hair. Heterozygotes (Hh) have wavy hair. Homozygous type A blood, heterozygous Rh+, straight hair. Heterozygous type B blood, homozygous Rh+, wavy hai Heterozygous type A blood, heterozygous Rh+, wavy hair. Heterozygous type A blood, homozygous Rh+, wavy hair. Type O blood, Rh-, straight hair.

MENDELIAN GENETICS Define the following terms: Gene: Homozygous: Allele: Heterozygous: Phenotype: Dominant: Genotype: Recessive: P, F1, F2 generations: Introduction to probability To understand genetics, it is essential to understand probability. The numerical value of the probability of an event can range from 0 (impossible) to 1 (certainty). For example, what is the probability of flipping a coin and getting tails? There are two possible outcomes (heads and tails) that are equally likely, but we are looking for the probability of just one of them (tails). Probability of tails = ½ = 0.5. What is the probability of tossing a six-sided die and getting a four? What is the probability of tossing a six-sided die and getting an even number? What is the probability of tossing a six-sided die and NOT getting a four? The first law of probability states that the results of one trial do NOT influence the results of later trials for…

Station 4: Pedigrees inidoned : no Pattern of inheritance (monohybrid, dihybrid, sex-linked, and genetically linked genes) can often be predicted from data, including pedigree, that give the parent genotype/phenotype and the offspring genotypes/phenotypes. III I II 1. Identify the type of inheritance in each of the following pedigrees(autosomal dominant, autosomal recessive, sex linked) AND EXPLAIN why it is that type of inheritance 20 2 21 O O 2. The pedigree below shows a family with a history of a recessive disease. DETERMINE the genotype of each individual for an autosomal trait

C. Give the genotypic and phenotypic ratios 1. Hemophilia is a disease caused by a gene found on the X chromosome. The recessive allele causes the disease. Tall (T) is dominant over short (t). A homozygous tall female carrier marries a short hemophiliac male. Predict the genotype and phenotype of their offspring.   2. In mice, the ability to run normally is a dominant trait. Mice with this trait are called running mice (R). The recessive trait causes mice to run in circles only. Mice with this trait are called waltzing mice (r). Hair color is also inherited in mice. Black hair (B) is dominant over brown hair (b). 2 heterozygous running, heterozygous black mice were crossed. Give the genotypic and phenotypic ratios of their offspring.

Lab Exercises: In these exercises, you will learn to use the Punnett square to determine geno- typic and phenotypic outcomes for monohybrid, dihybrid, incomplete, codominant, epistatic, and sex-linked traits.

Monohybrid Cross Worksheet Directions:  Answer each of the following questions using a Punnett Square and the rules of monohybrid crosses. The allele for dimples (D) is dominant to the allele for no dimples (d).  A man heterozygous for dimples marries a woman who is also heterozygous for dimples.   What is the man’s genotype and the woman’s genotype? What is the man’s phenotype and the woman’s phenotype? Do a cross to determine all potential dimple genotypes and phenotypes for the offspring of this man and woman. The allele for hitchhiker’s thumb (h) is recessive to straight thumb (H).  If a man and his wife are both homozygous recessive, will any of their offspring potentially have hitchhikers thumb?  What is the man’s genotype and the woman’s genotype?
