1. Warm Up

2. -Offspring possible genotypes: -Offspring possible phenotypes: -Ratio:
Be able to: 1. Use Punnett squares to predict genotypic and phenotypic ratios of offspring 2. Explain Mendel’s law of segregation and how it relates to a monohybrid cross.
1. A Tall plant (T) is dominant to a short plant (t). If all offspring of a cross are heterozygous, what were the genotypes of the parents?
2. In humans, brown eyes are dominant over blue eyes. What type of offspring would you expect if you crossed a heterozygous brown eyed person to a heterozygous brown eyed person?
