REVIEW CHAPTER TENGENETICS

Number One

Write down a genotype that would display the heterozygous trait.

Number Two In humans, brown eyes (B) are dominant over blue (b)*. A brown-eyed man marries a blue-eyed woman and they have three children, two of whom are brown-eyed and one of whom is blue-eyed. Draw the Punnett square that illustrates this marriage

Number ThreeWho is the father of genetics? What did he use to do his experiments?

Number FourLooking at the punnet square below, write the PHENOTYPIC ratio:

Number FiveThe different forms of a gene are called:

A. AlleleB. CharactersC. ChromosomesD. Phenotype

Number SixIf an organism has a diploid number of 20, what would their haploid number be?

Number Seven The gene for tallness (T) is dominant

over the gene for shortness (t) in pea plants. A homozygous dominant pea plant is crossed with a heterozygous pea plant, and 200 seeds are produced. Approximately how many of these seeds can be expected to produce plants that are homozygous dominant?
