Final answer:
The sex producing two different types of gametes with respect to sex chromosomes is the heterogametic sex, with males being an example in humans.
Step-by-step explanation:
The sex that produces two different types of gametes with respect to the sex chromosomes is called the heterogametic sex. In sexual reproduction, the mechanism that produces haploid gametes from diploid cells is called meiosis. This process involves two stages: meiosis I and meiosis II. In humans, the male sex is heterogametic, producing gametes with either an X or a Y chromosome (sperm), which results in either male or female offspring after fertilization. In contrast, the female sex is homogametic, producing gametes that contain a single type of sex chromosome, namely X (eggs).
