If AaBbCcDd is mated to AaBbCcDd (no gene interactions among all genes), what is the probability that the offspring will have either the phenotype aaB_CcDD or the genotype AAbbCcD_?
Homework Answers
AaBbCcDd × AaBbCcDd
This is a tetrahybrid cross. Convert it to 4 monohybrid crosses.
Aa × Aa = 3/4 A_, 1/4 aa = 1/4 AA, 2/4 Aa, 1/4 aa
Bb × Bb = 3/4 B_, 1/4 bb = 1/4 BB, 2/4 Bb, 1/4 bb
Cc × Cc = 3/4 C_, 1/4 cc = 1/4 CC, 2/4 Cc, 1/4 cc
Dd × Dd = 3/4 D_, 1/4 dd = 1/4 DD, 2/4 Dd, 1/4 dd
Probability of phenotype aaB_CcDd = 1/4 × 3/4 × 2/4 × 1/4 = 6/256
Probability of genotype AAbbCcD_ = 1/4 × 1/4 × 2/4 × 3/4 = 6/256
Final answer = 6/256 + 6/256 = 12/256 = 6/128 = 3/64
Answer is 3/64
Please rate high.

In a certain plant species, inheritance of fruit size is controlled by four genes, each of which has two alleles that show incomplete dominance and each of which contributes equally to an individual’s phenotype. Plants with the largest fruits have the genotype AABBCCDD, while those with the smallest fruits have the genotype aabbccdd. a) How many possible genotypes for fruit size are there in this species? b) Based on genotype alone (ignoring environmental factors), how many possible phenotypes for fruit...

Which of the following statements is false? Epistasis involves interactions among different genes, to influence phenotype. When an allele is dominant, the heterozygous combination is the same phenotypically as one of the homozygotes. Dominance refers to the form of expression of a gene in relation to its allele (or alleles). Epistasis involves interactions between alleles of a single gene.

7) You cross individuals with genotypes as given below. The seven genes have a typical Mendelian pattern of inheritance, and each gene has two alleles that have a complete dominance relationship: AaBbCcddEeFFgg X aabbCcDdEeFfGg A) What is the probability that one offspring from this mating will have the genotype AaBbccDdeeFFGg (4 pts.)? B) What is the probability that one offspring from this mating will express the dominant phenotype for all seven genes (4 pts.)?

In chickens, comb shape is determined by non-epistatic interactions between genes at two loci (R, r and P, p). A walnut comb is produced when at least one dominant gene R is present at one Single Rose locus and at least one dominant gene C P is present at a second locus (genotype R P ). A rose comb is produced when at least one dominant gene is present at the first locus and two recessive genes are present at...

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...
