Answer:
The conditions for natural selection are:
- overproduction of offspring
- variation among organisms in a population
- favorable adaptations selected by nature
Explanation:
- Natural selection is the continuous process of reproduction and survival that is caused by the contrast and differences due to phenotype.
- Overproduction of species creates the competition and only the one survived through the natural selection grows to the next generation.
- Similarly variations in the phenotypic organization of species, their adaptation process etc causes the natural selection.
- Natural selection is the gateway for the evolution.
Answer: Called the meniscus.
The correct answer is option B, 50%
Let us take the following case:
Genotype of heterozygous parent - (Aa)
Genotype of homozygous parent – (aa)
Allele I - (Aa)
Allele II – (aa)
The cross between the two is shown below:
Aa X aa
Aa, Aa, aa, aa
There are 50 % Aa, and 50 % aa allele.
Thus, the allele I (Aa) is 50 %.
