Final answer:
The statement is true; geneticists have discovered the existence of meiotic drive genes.
Step-by-step explanation:
True
Geneticists have indeed discovered the existence of meiotic drive genes. These genes have alleles that, when present in a heterozygous state, can become incorporated into more than 50 percent of the gametes. This phenomenon is known as meiotic drive, where certain alleles have a higher probability of being transmitted to the next generation.
