PRE-LAB QUESTIONS - Genetics - Lab #9 1. Humans inherit two alleles for every gene. For an example, gene "R" provides the instructions for face shape. The dominant allele for the gene is denoted as R and the recessive allele for the gene is denoted as r. The dominant phenotype is a round face shape and the recessive phenotype is a square face shape. Use this information to answer the questions below: What is the genotype of a homozygous dominant...

There are four alleles for the bald gene that control hair growth in an individual. A bald man who is heterozygous for the first two alleles has children with a non-bald woman who is homozygous for the third allele. All of their children are non-bald. How many gametes will the father produce? Write the allele(s). How many gametes will the mother produce? Write the allele(s). Draw the Punnett Square and the resulting offspring. Draw the relationship between alleles in the...

Practice Using a Punnett Square. Punnett Squares are tools to identify outcomes known genotypes. They can be used to help infer probabilities of genotypes and from a particular cross. of possible crosses between individuals of phenotypes amongst offspring lele forms "A" and "a". A woman is heterozygous, so she can produce eggs with Consider a gene with all 9. and Write them across the top of the Punnett Square below the following...

Which of the following is true regarding dihybrid crosses? A. Each parent involved in the cross is heterozygous for at least one of the two genes being assessed. B. Two gene loci are assessed and the parents can be any genotype at these two loci. C. There are 9 different fertilization possibilities. D. The ratio 9:3:3:1 means that of the possible outcomes in offspring; 9/16 will express the dominant phenotype for both loci, 3/16 will express the dominant phenotype for...

The occurrence of the NN blood group genotype in the US population is 1 in 400, consider NN as the homozygous recessive genotype in this population. You sample 1,000 individuals from a large population for the MN blood group, which can easily be measured since co-dominance is involved (i.e., you can detect the heterozygotes). They are typed accordingly: BLOOD TYPE GENOTYPE NUMBER OF INDIVIDUALS RESULTING FREQUENCY M MM 490 0.49 MN MN 420 0.42 N NN 90 0.09 Using the...
