6. Why does meiosis increase genetic variation in the offspring, but mitosis does not? (1 point)
brilliants [131]
Meiosis involves crossing over where chromosomes exchange genetic segments, resulting in different sets of chromosomes. Each time an egg or sperm created, it is different due to this recombination. Mitosis on the other hand is non-sex cells replicating exact copies of themselves which lead to no genetic variation as they aren't involved in producing offspring.

Which is the most likely result if the Ubx gene was activated either before or after it normally is activated in the sequence of
BigorU [14]

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.
