Question

why sex?

1. what is unusual about the reproduction of the desert grassland whiptail lizard?
2. what are three disadvantages of sexual reproduction, particularly the presence of males?
3. most species on earth use (sexual / asexual ) reproduction.

Explanation:

1. The desert grassland whiptail lizard is unusual because it reproduces asexually (parthenogenesis). Females can produce offspring without mating with males.
2. Three disadvantages of sexual reproduction (due to males) could be:

• Males do not directly contribute to offspring production (in terms of gestation or egg - laying in some species).
• Energy is spent on mate - finding and courtship behaviors.
• Genetic recombination in sexual reproduction may break up beneficial gene combinations.

1. Most species on earth use sexual reproduction. Sexual reproduction provides genetic diversity which is important for adaptation to changing environments.

Answer:

1. It reproduces asexually (parthenogenesis).
2. - Males do not directly contribute to offspring production. - Energy is spent on mate - finding and courtship. - Genetic recombination may break up beneficial gene combinations.
