Answer:
The reasons are explained below -
Explanation:
The large finches living on the Galapagos islands are different from the original source population from a nearby islands because of the following reasons -
- A natural selection favored only the large finches because they are more fit to the current environmental conditions.
- A genetic drift has been occurred in the two populations living on the nearby islands.
- Due to the separation of habitat on both the islands, the gene flow between the two islands is reduced.
All the above listed reasons are responsible for the difference in the finches found on the two islands.
Answer:
True
Explanation:
Tropical rain forest are one of the important biomes of the world that is characterized by a short or no dry season and a precipitation of overall 60 mm each month. They are also known as lowland equatorial evergreen rainforest. If we talk about location, they mostly are found between fall between the Tropic of Cancer and the Capricorn since they lie near to equator and they receive sufficient amount of sunshine and rain.
Due to their location near the equators, they receive greater amount of sunshine than other biomes and when sunshine is greater the rate of water evaporation is also greater that results in more rainfall.

Answer:
<h2>(14+16)/1000 *100= 3</h2>
Explanation:
Parental combinations are always more common then other recombinant progenies.
A female fly is heterozygous for three X-linked genes crossed with an abc/Y male. . If single crossover occurs between a & b and between b & c, then the double cross is that, which occurs in both.
Double cross over progeny are always least in number, so here double cross occurs are in abC 14 and ABc 16.
So we are expecting that number of double cross over progeny= (14+16)/1000 *100= 3
