The results from Corn # 1 and corn No #2 show that alleles assort independently into gametes. Due to this genetic variations occur.
Homozygous means that the alleles for a gene are similar. Heterozygous means that the alleles for a gene are different.
A dominant trait is the one in which the dominant allele suppresses the effect of the recessive allele. The recessive allele gets masked by the dominant allele.
