"The heterozygous genotype resulted from inheriting different alleles from each parent."

"In a heterozygous individual, one allele may be dominant while the other is recessive."

"Researchers often study heterozygous organisms to understand genetic variation."

"The heterozygous exhibited traits that differed from the homozygous individuals."

"To analyze genetic diversity, scientists often focus on heterozygous populations."

"Being heterozygous for a trait can provide a survival advantage in certain environments."
