b) G. H. Hardy
c) William Bateson
d) Reginald Punnett

2. What is the apprentice of an organism or the trait that is seen?
a) genotype
b) Punnett square
c) allele
d) phenotype

3. Why are Punnett squares used?
a) To physically help scientists understand physics
b) to help author books on genetics
c) To determine the probability that an offspring would have a specific trait
d) To decode the human genome

Answer 1

The offspring are represented by the four boxes and carry each box represents 25% chance that the offspring will carry a particular trait.

The offspring will have a dominant genotype unless two recessive alleles are passed to it.
1. Homozygous Dominant - Ex. RR
2. Heterozygous - Ex. Rr
3. Homozygous Recessive - Ex. rr

1)What percent chance will the offspring have red flowers?
2) What combination of parent genotypes would assure that the offspring would have white flowers?
