What is the process of alleles of a gene pair separating completely and cleanly from each other during meiosis known as?
Independent Segregation
In a monohybrid cross, what is the result of crossing homozygous individuals that are different from each other at one gene locus?
Offspring will have a mix of genotypes and phenotypes
What is the result of a dihybrid cross involving two homozygous individuals that are different from each other at two gene loci?
