Final answer:
The law of segregation states that during gamete formation, alleles for each gene segregate so that each gamete carries only one allele for each gene. Each parent can only pass on one allele for each trait. This allows for the inheritance of specific alleles from each parent.
Step-by-step explanation:
The law of segregation, proposed by Gregor Mendel, states that during gamete formation, the alleles for each gene segregate from each other so that each gamete carries only one allele for each gene. This means that each parent can only pass on one allele for each trait to their offspring.
For example, if a parent plant has two different alleles for seed color, one for yellow and one for green, the alleles segregate during gamete formation, and the offspring will inherit either the yellow or green allele from the parent.
