Unit 4 week 4
1. Punnett Squares
⪢ A diagram used to predict the genotypes
of a particular cross or breeding
experiment.
⪢ Named after Reginald Punnett who created
the technique.

READ THE INSTRUCTIONS!
If you read carefully, it’s
really simple. If you don’t
read, you’re going to get
confused and frustrated…

5. Cross a red flower (RR) with a heterozygous
red flower (Rr).
What will the offspring look like (phenotype)?
What will be the possible genotypes?
6. What is Independent Assortment?
⪢ States that the alleles of two (or more)
different genes get sorted into gametes
independently of one another
⪢ In other words, the allele a gamete receives
for one gene does not influence the allele
received for another gene
7.
8. What is the Law of Segregation?
⪢ Only one of the two gene copies
present in an organism is
distributed to each gamete (egg or
sperm cell) that it makes
⪢ Where the gene ends up is totally
random
