- Q1In the human body, skin, liver, muscle, and nerve cells all originated from one cell containing half-genomes contributed from each parent. This process is known as –differentiationcleavagespeciationexpression30s
- Q2Muscle cells of one animal differ from muscle cells of another animal due to differences in –the cell cyclegenetic sequenceDNAgene expression30s
- Q3Cell differentiation is critical during embryonic development. The process of cell differentiation results in the production of many types of cells, including germ, somatic, and stem cells. Cell differentiation is most directly regulated by —DNAsugarslipidsATP30s

- Q5If several pea plants with the genotype T TYy are crossed with pea plants with the genotype Ttyy, what percentage of the offspring will be expected to have the T TYy allele combination?75%50%25%40%45s
- Q6In cocker spaniels the allele for a black coat color (B) is dominant over the allele for a brown coat color (b). If a brown cocker spaniel is crossed with a heterozygous black cocker spaniel, which of the following genotypic ratios can be expected0 BB: 2 Bb: 2 bb2 BB: 0 Bb: 2 bb2 BB: 1 Bb: 0 bb1 BB: 2 Bb: 1 bb45s
- Q7Tomato plants usually have hairy stems. Hairless stems are present in tomato plants that are homozygous recessive for this trait. If the stem characteristics are determined by a single gene, what is the expected outcome of crossing two tomato plants that are heterozygous for hairy stems?50% hairy stems: 50% hairless stems75% hairy stems: 25% hairless stems100% hairless stems100% hairy stems45s
- Q8In cattle the allele for cloven hooves (H) is dominant over the allele for mule-foot hooves (h). The phenotype for each trait is shown in this picture. What is the probability of cloven hooves in the offspring of parents that are heterozygous for the trait?75%50%100%25%45s
- Q9In guinea pigs, the allele for a rough coat (R) is dominant for the allele for a smooth coat (r). A heterozygous guinea pig and a homozygous recessive guinea pig are mated. Which of the following lists the distribution of genotypes most likely to be seen in the offspring?100% Rr25% RR, 50% Rr, and 25% rr75% Rr and 25% rr50% Rr and 50% rr45s
- Q10In cattle, the allele for short horns (S) is dominant over the allele for long horns (s). Two heterozygous short-horn cattle are bred and produced four offspring. What percentage would you expect to have long horns?50%75%100%25%45s

- Q12Jennifer’s brown and white dog had four puppies. Three of the puppies were solid brown and one was brown and white, like the mother. Jennifer concluded that –coat color is not a genetic traitbrown is a dominant coat colorwhite is a dominant coat colorbrown is a recessive coat color45s
- Q13Brown eyes are dominant over blue eyes for a particular litter of puppies. What could account for a litter of puppies that had more blue eyes than brown eyes?Genes from both parents were dominant.Genes from both parents were recessiveEach parent provided both dominant and recessive genes in equal numbers.One parent provided dominant genes and one parent provided recessive genes.45s

Which of the following must be true about the genetic material of a fruit fly with long wings?It must be heterozygous for short wings OR homozygous for short wings.It must be homozygous for long wings OR heterozygous for long wings.It must be heterozygous for long wings OR heterozygous for short wings.It must be homozygous for long wings OR homozygous for short wings.45s
