Write the alleles from one parent along the top of the box and the alleles from the other parent along the side of the box. Make a box with four sections. Write the alleles from one parent along the top of the box and the alleles from the other parent along the side of the box. 2 2 Complete the Punnett square by writing the gene combinations in the correct boxes. (Note: The dominant allele is listed first). Complete the Punnett square by writing the gene combinations in the correct boxes. (Note: The dominant allele is listed first). 3 3

(L) Pg 198 #8 Pg 199, #15 Assume that Y is the dominant allele for yellow seeds and y is the recessive allele for green seeds. What is the probability that a pea plant with the genotype Yy crossed with the genotype yy will have offspring with the genotype yy? Everyone in Squidward’s family has light blue skin which is dominant to light green skin. Assume that one of Squidward’s sons, who is heterozygous for the light blue body color, married a girl that was also heterozygous . What are the chances that the child will have light green skin.
