What is true about DNA mutations?

Biology
1 answer:
JulsSmile [24]2 years ago

Answer:

B

Explanation:

Crossing over is the process involved during meiosis of two chromosomes sharing genetic information with each other from each parent. This happens so the two daughter cells or sister chromatids have a variety of genetic information and so they are not completely identical. This leads to genetic diversity or variation.

Leaves in areas of ___ humidity have a steeper concentration gradient so water diffuses out of the leaf
tresset_1 [31]

Leaves in areas of low humidity have a steeper concentration gradient so water diffuses out of the leaf fast.

<h3>What is humidity?</h3>

Humidity is used to determine the concentration of water vapour that is available in the air.

when the vapour is high there is high relative humidity when the vapour is low there is low relative humidity and water leaves the surface of leaf fast.

Therefore, Leaves in areas of low humidity have a steeper concentration gradient so water diffuses out of the leaf fast.

Evolution can be guided by random processes. What is the effect called when some genotypes are lost in a small population over t
soldi70 [24.7K]

Answer:

Genetic drift

Explanation:

Genetic drift is defined as the random change in allelic frequencies from one generation to the other.

Genetic drift is an evolutionary mechanism in which the allelic frequencies in a population change through many generations. Its effects are harder in a small-sized population, meaning that this effect is inversely proportional to the population size. Genetic drift results in some alleles loss, even those that are beneficial for the population, and the fixation of some other alleles by an increase in their frequencies. The final consequence is to <u>randomly</u> fixate one of the alleles. Low-frequency alleles are the most likely to be lost. Genetic drift results in a loss of genetic variability within a population.  

Genetic drift has important effects on a population when this last one reduces its size dramatically because of a disaster -bottleneck effect- or because of a population split -founder effect-.
