Suppose that the sex of the offspring of
a species
of fish is determined by water tempera- polyphenism
ture.
In this case, what type of trait is sex?
Polyphenism is a biological phenomenon
where a single genotype (genetic make-
polyphenism up) can produce multiple distinct pheno-
types (observable traits), depending on
environmental conditions.
Some species of butterflies develop dif-
ferent wing patterns depending on the
Polyphenism
season in which they mature.
This is an example of?
All female honeybees are genetically
similar, but nutrition (like royal jelly) de-
termines whether a female becomes a
worker or a queen.
In some species of reptiles, the temper-
Polyphenism
ature at which eggs incubate can deter-
mine whether the offspring are male or
female.
