Question

If you plotted hormone levels for the lizard shown in gray, how would your graph differ from the graph in (b)?

Short answer

The estradiol level would be high in grey lizards when its level is low in a brown lizard. Similarly, the level of progesterone would be high in grey lizard when its level is low in a brown lizard.

Step-by-step solution

A. uniparens

A. uniparens individuals can switch sex roles almost two or three times during a breeding season. The sexual behavior of these lizards affects the ovulation cycles and alters the sex hormone levels such as estradiol and progesterone.

Role of sex hormones

Hormones that regulate sexual growth and development are called sex hormones. Sex hormones such as estradiol and progesterone are involved in mammalian reproduction. They are responsible for the growth and function of the uterus.

Hormones levels for gray lizard

The graph shows that when the brown lizard's estradiol level is low, the grey lizard's estradiol level would be high because it behaves like a female partner.

Similarly, when the brown lizard's progesterone level is low, the grey lizard's progesterone level would be high because of its sexual behavior as a female.
