3. Suppose there is a Mendelian trait with incomplete dominance. Therefore, you can tell the genotype of every individual by its phenotype. If one of the two homozygotes occurs with a frequency of 6%, what would be the frequency in the population of the other homozygote?
Homework Answers
Suppose there are two alleles, A and B.
AA = phenotype a
AB = phenotype b
BB = phenotype c
Genotypic frequency of AA = 6% = 6/100 = 0.06
Allelic frequency of A = √0.0 6 = 0.245
Therefore, allelic frequency of B = 1 - 0.245 = 0.755
Genotypic frequency of BB = 0.755 × 0.755 = 0.57 = 57%
Other homozygote would be 57%.

1) Select the true statements about dominant and recessive genes, assuming complete penetrance of the genotype. Circle all that apply. (1.5) For an offspring to be phenotypically dominant for a trait, at least one parent will show the trait. For an offspring to be phenotypically recessive for a trait, at least one parent will show the trait. In incomplete dominant or codominant traits, heterozygotes will have a different phenotype than either homozygote. If both parents show a recessive trait, then...

Question 1 (30 points) Suppose a lizard species demonstrated incomplete dominance for its skin color. A homozygous individual (BB) would be blue. A homozygous (bb) individual would be red. A heterozygous (Bb) individual would be purple. What would be the phenotypes (skin color) and the genotypes (alleles: BB, Bb, bb) for the offspring of a blue lizard crossed with a red lizard? You can use a Punnett square to figure out the answer, but you don't need to include a...

Human Mendelian Traits Like most complex organisms, humans possess an enormous number of genetically inherited characteristics. Some of these are Mendelian in nature, i.e., one gene with two alleles (one true dominant, one true recessive) producing two easily observed traits. You and your partner will evaluate yourselves and each other for your phenotypes, then list the appropriate genotype possibilities. If you are dominant for the trait then assume you are heterozygous unless you know your parents phenotype. 1. Rolling the...

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...

You have three genes on the same chromosome - A, B and C. Each gene has two alleles in a dominant/recessive relationship. For these genes the homozygous recessive has the mutant phenotype for that trait, the dominant phenotype = wild type for that trait. allele A is dominant to a; phenotype a = mutant for trait a; phenotype A = wild type for trait A allele B is dominant to b; phenotype b = mutant for trait b; phenotype B...

Consider a hypothetical population with two genes. Each of these two genes have two alleles (A & a, B & b). These genes are not linked, and these genes are true dominant/recessive (i.e. not co-dominant or incomplete dominance... "A" dominant to "a" and "B" dominant to "b"). Suppose you perform a monohybrid cross of an AABB homozygote with an aabb homozygote through to the F2 generation. In 2019, the genotype frequency of individuals with "aa" (regardless of their B/b genes)...
