Hox genes are regulatory genes

Question

in multicellular animals that code
for transcription factors that
determine the basic body plan in
a developing embryo. They act
as switches that turn other genes
on and off. Scientists have found
that a mutation in a fruit fly hox
gene produces flies with legs
instead of antennae sticking out
of their heads. Another hox gene
mutation results in fruit flies with
two pairs of wings instead of one
pair. Hox genes affect body plans
by controlling the expression of
many other genes.
Many multicellular animals have
the same hox genes. Which
statement is evidence for this
claim?
(1 point)

Answer 1

A comparison of the hox genes in different multicellular animals shows that they have similar sequences or structures.

Answer 2

the awnsers were
The body plans of complex animals typically have a large number of
mutations.
The body plans of complex animals are very similar to one another.
The body plans of complex animals change over generations.
There is a wide variety of body plans in complex animals.

Answer 3

The correct answer is "The body plans of complex animals are very similar to one another."
