red beetle with genotype AABB is crossed with a yellow beetle with genotype aabb. The heterozygous F1 beetles are crossed to each other to make the F2 generation. If the beetle color trait is controlled by dominant epistasis of allele B over gene A, what phenotype would you expect for an individual with genotype aaBb?   Group of answer choices 1.red 2.yellow 3.another color, but not red or yellow 4.either red or yellow

In frost moths, two alleles of one gene determine the character difference of spotted versus striped wings and two alleles of a separate, independent gene determine the character difference of orange wing background versus white wing background. The results for four matings of moth phenotypes are shown below.     Number of progeny Mating Parental Phenotypes Spotted/orange Spotted/white Striped /orange Striped  /white 1 spotted/orange x striped/orange 623 0 637 0 2 spotted/white x striped/orange 0 0 0 712 3 spotted/white x striped/orange 122 131 128 133 4 spotted/orange x striped/white 0 0 430 422 striped= S(dominant) spotted=s (recessive) white= W(dominant) orange=w (recessive)   What are the genotypes of each parent in each cross?  If more than one genotype is possible, list the alternative possibilities.  (Remember that each mating involves a separate set of parents, so the 4 matings involve 8 separate…

In pea plants, round peas (R) are dominant to wrinkled peas (r). You do a test cross between a pea plant with wrinkled peas (genotype rr) and a plant of unknown genotype that has round peas. Result: 4 plants with round peas. What is the unknown parent? Use Punnett square on homework to help answer the question. O a. Homozygous dominant O b. Heterozygous O c. Homozygous recessive O d.

ABO blood group is co-dominant for AB and O is recessive. Rh (+/-) factor is completely dominant. A man with O/positive blood and a woman with A/negative blood have six children. All of their children have A + blood type. What can you conclude about the parents’ genotypes? Group of answer choices Both mother and father are likely homozygous  at both loci Mother was homozygous at the ABO locus but heterozygous at the Rh factor locus Father was homozygous at the ABO locus but heterozygous at the Rh factor locus Mother was heterozygous at both loci

If one human parent is heterozygous for blood type A (IAi), and the second parent is heterozygous for blood type B (IBi), what are the expected phenotypic ratios in their children? a. 1/4 with blood type AB, 1/4 with blood type A, 1/4 with blood type B, and 1/4 with blood type O b. 1/4 with blood type A (IAi), 1/2 with blood type AB (IAIB), and 1/4 with blood type B (IBi) c. 1/2 with blood type AB (IAIB), and 1/2 with blood type O (ii) d. 1/2 with blood type A (IAi), and 1/2 with blood type B (IBi) e. 1/2 with blood type A (IAi), and 1/2 with blood type O (ii)

Three different genes determine the coat colour of cats. One of the genes controls the black-based coat colour. There are three alleles for black-based coat colour genes with the following order of dominance: black (B) > chocolate (bch) > cinnamon (bc). Two black cats were crossed. The offspring produced were three black kittens and one chocolate kitten. What is the probability of having a male chocolate kitten? Select one: a. 0.50 b. 0.25 c. 0.13 d. 0.06

A scientist is investigating the inheritance of two autosomal recessive genes in rat, ear length (long is dominant to short) and fur color (gray is dominant to white). The table below provides the number of observed off-spring for each phenotype, when heterozygous rats are crossed.  What are the expected values for each phenotype? Phenotype Observed Expected Long, gray 189   Long, white 56   Short, gray 74   Short, white 23   Total 342

In swallowtail butterflies, let's pretend that the R gene codes for coloring on the forewing. The R1 allele, which codes for red color, is dominant to the R2 allele, which codes for white color. If R1 is a recessive lethal allele, what phenotypic ratio would you expect when crossing two swallowtails with red forewings?  1 red : 2 white  1 red : 3 white  3 red : 1 white  there is not enough information given to answer this question  1 red : 1 white  2 red : 1 white

In rabbits, black hair is due to a dominant allele B and brown hair to its recessive allele b.  Short hair (H) is dominant to long hair (h).  In a cross between a homozygous black, longhaired rabbit and a brown, homozygous shorthaired one, what would the F1 generation look like?  If you did not know the genotype of an F1 rabbit, you could determine its genotype by a test cross in which it is crossed with an animal with which phenotype AND genotype If you carried out this test cross, what phenotypes and in what ratio would you expect? What phenotypes in what ratio would be expected in the F2 generation?
