During the lifecycle of the plant we can encounter both haploid and diploid forms.
First two people will have widows peak, last two will have straight hairline.
widows peak: 50%
straight hairline: 50%
Answer: Option C) recombination
Explanation:
Recombination is the process in which the chromosomes are broken and the fragments are rejoined in new combinations.
In eukaryotes, recombination is achieved by reassortment of chromosomes during meiosis and by crossing over.
The feature that allows this to happen is a semipermeable membrane (selectively permeable membrane). This allows the cell to decide what gets in, it allows things like hydrocarbons and oxygen and water to pass, but prevents large sugars from getting in. The process of water passing through the holes in osmosis which is the diffusion of water across this semipermeable membrane.
The answers are Stabilizing selection, directional selection and disruptive selection respectively.
<h3><u>Explanation</u>:</h3>
In case of a population of a species, there exists both the homozygous alleles as well as the hybrid of the two characters. This leads to co existence of both hybrids and homozygotes together in a population.
Now because of the natural selection, there remains some characteristics in either homozygotes or in hybrids which gets special advantages over other. So nature selects the preferred race and the number of those individuals in the population increase.
If number of one of the homozygotes increase, then it's the directional selection.
If the number of the hybrids increase, then its Stabilizing selection.
And if both the homozygotes are selected, then it's divergent selection.
