The main land life was as exceptionally crude plants extremely close to the water line of the coasts, presumably greeneries and green growth and were of a non-vascular nature.
The Ordovician Period started with a noteworthy eradication called the Cambrian– Ordovician annihilation occasion, about 485.4 Mya (million years prior). It went on for around 42 million years and finished with the Ordovician– Silurian elimination occasions, about 443.8 Mya (ICS, 2004) which cleared out 60% of marine genera.
The timeframe that occurred 488 to 443 million years back. Amid the Ordovician time frame, some portion of the Paleozoic time, a rich assortment of marine life thrived in the tremendous oceans and the primary crude plants started to show up ashore—before the second biggest mass annihilation ever finished the period.
If it was a double heterozygote, then aabb will be AaAaBbBb.
It will form 4 types of gametes since we have Aa, Bb. It will have aB, AB, ab, Ab.
An individual will form
only 2 type of gametes, Aa, Bb.

Answer:
The trait must make the individual more fit to survive. True
Explanation:
Darwin proposed that genetic variations are present in natural populations. Some genetic traits become beneficial under the changed environmental conditions. The organisms with these genetic traits are able to survive and reproduce better than the organisms that lack them. This results in an increased proportion of the beneficial genetic traits in the population over generations as the individuals having those traits reproduce more.
The presence of antibiotic resistance is a beneficial genetic trait that allows bacteria to survive in the presence of antibiotics. Natural selection favors the bacterial having antibiotic resistance and increases their proportions in the population over generations.
