Biology for IGCSE & O level - Inheritance (Section 5 - No. 30)
Which of the following is a key principle of Mendel's Law of Segregation?
Alleles for a trait separate during gamete formation.
Genes located on different chromosomes assort independently.
Both alleles are always expressed in heterozygotes.
The phenotype is determined by multiple genes.
Explanation
The Law of Segregation states that alleles for a trait separate during meiosis, so each gamete receives only one allele for a gene.
