A) That organisms have changed over time
Answer:
45
Explanation:
Both parents are hetero-zygous, so each has alleles Ll.
When Ll crosses with Ll, we have
LL 25%
Ll 50%
ll 25%
So out of 180 offspring, we expect about 25% to have short wings, or
25%*180 = 45
Answer:
D. The insect develops legs in other parts of its body.
Explanation:
HOX genes, also known as homeotic genes, are evolutionarily conserved genes (containing homeobox sequences) that encode master regulators of embryonic development in animals. Hox genes modulate the body plan of an embryo along the head-tail axis. In general, these genes are arranged in the same order as they are transcriptionally expressed along the anteroposterior body axis. Moreover, Ultrabithorax (Ubx) is a Hox gene that is responsible for the proper development of the third thoracic segment in insects. In <em>Drosophila</em>, it has been shown that different segments of the leg regulate their size in response to Ubx expression.
