  1. Bio 130 – Quiz March 28

  2. Q. 1 - Imagine crossing a pea heterozygous at the loci for flower color (white versus purple) and seed color (yellow versus green) with a second pea homozygous for flower color (white) and seed color (yellow). What types of gametes will the first pea produce? • two gamete types: white/white and purple/purple • two gamete types: white/yellow and purple/green • four gamete types: white/yellow, white/green, purple/yellow, purple/green • four gamete types: white/purple, yellow/green, white/white, and purple/purple • one gamete type: white/purple/yellow/green

  3. Q. 2 - A cross between homozygous purple-flowered and homozygous white-flowered pea plants results in offspring with purple flowers. This demonstrates • the blending model of genetics. • true-breeding. • dominance. • a dihybrid cross. • the mistakes made by Mendel.

  4. Q. 3 – In dachsunds Brown hair (B) is dominant to yellow hair (b). Curly hair (C) is dominant to straight hair (c). We mate a female BBcc with a male bbCC. What is the chance of a puppy with yellow curly hair? • 0 • 1/4 • 1/8 • 3/8 • 3/16

  5. Q. 4 – In dachsunds Brown hair (B) is dominant to yellow hair (b). Curly hair (C) is dominant to straight hair (c). We mate a female BbCc with a male bbCC. What is the chance of a puppy with yellow curly hair? • ½ • ¼ • 1/8 • 3/8 • 1/16
