Without genetic variation, the mechanisms of evolutionary change will not occur. There are several sources of genetic variation within a breeding population: sexual reproduction, mutation, and gene flow. Illustrated here is a key
component of two of the three sources of genetic variation:recombination. How does recombination contribute to
evolution?
A)
B)
The exchange of genetic information during meiosis results in the
formation of new alleles.
During recombination, homologous chromosome exchange pieces of
genetic information, increasing genetic variability.
Once reproduction has occurred, chromosomes exchange pieces of genetic
information, resulting in a new set of chromosomes.
During recombination, homologous chromosome exchange pieces of
genetic information, creating mutations that drive evolutionary change.
C)
D)

answer; i do believe that the correct answer is; ///mendelian genes are at specific loci on the chromosome and, in turn, segregate during meiosis;

the correct answer, according to e2020, is the second choice there is an occluded front in region a and a cold front in region b.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
