Assume that the genes for hairline and earlobes are on different pairs of homologous chromosomes. Determine the genotypes and phenotypes of the offspring from a cross if both parents are heterozygous for both traits.
( First determine the genotypes for each parent. (2) Determine the gametes, but remember each gamete has one
allele for each trait (gametes are haploid). (3) Construct a Punnett square with 16 boxes that has four different
gametes from each parent along the top and the left edges. (This is an application to demonstrate Mendel's Law
of Independent Assortment.) ( List the results of genotypes and phenotypes as ratios. A
