The mating of totally unrelated homozygous strains of corn produced a new strain of corn that was
very different from both parental strains in many characteristics. Give some reasons to explain this
phenomenon What will be an ideal response?
Concepts to Consider: The offspring strain of corn will be heterozygous for many of its traits. As
such, the observed differences may be due to incomplete dominance, codominance, multiple alleles,
epistatis, or polygenic inheritance

In summer squash, spherical-shaped fruit has been shown to be dominant to elongated fruit. On one
occasion, two different spherical varieties were crossed and produced all disk-shaped fruits. When these hybrid disk-shaped fruits were crossed, they produced 75 disk-shaped fruits, 48 spherical fruits, and 9 elongated fruits. Explain. What will be an ideal response?
