Describe what happened when Mendel crossed purebred tall pea plants with purebred short pea plants.

You toss a coin five times and it lands heads up each time. What is the probability that it will land heads up on the sixth toss? Explain your answer.

In guinea pigs, the allele for black fur (B) is dominant over the allele for white fur (b). In a cross between a heterozygous black guinea pig (Bb) and a homozygous white guinea pig (bb), what is the probability that an offspring will have white fur? Use a Punnett square to answer the question.

Describe the role of transfer RNA in protein synthesis.

How can mutations affect protein synthesis?

In rabbits, the allele for a spotted coat is dominant over the allele for a solid-colored coat. A spotted rabbit was crossed with a solid-colored rabbit. The offspring all had spotted coats. What are the probable genotypes of the parents? Explain

A new mutation in mice causes the coat to be twice as thick as normal. In what environments would this mutation be helpful? Why?

Why are mutations that occur in an organism’s body cells not passed on to its offspring?

In peas, the allele for green pods (G) is dominant over the allele for yellow pods (g). The table shows the phenotypes of offspring produced from a cross of two plants with green pods.

Calculate what percent of the offspring produce green pods. Calculate what percent have yellow pods

In peas, the allele for green pods (G) is dominant over the allele for yellow pods (g). The table shows the phenotypes of offspring produced from a cross of two plants with green pods.

What is the genotype of the offspring with yellow pods? What are the possible genotypes of the offspring with green pods?

In peas, the allele for green pods (G) is dominant over the allele for yellow pods (g). The table shows the phenotypes of offspring produced from a cross of two plants with green pods.

What are the genotypes of the parents? How do you know?
