If there are 150 dominant alleles and 50 recessive alleles for a trait, what is the allele frequency for recessive alleles for this trait? * O 0% O 25% O 50% O 75% O 100%​

a, i am pretty sure.

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".

explanation:

the sun shines white and black light to our planet. the white light has all the colors in it. in our upper atmosphere, we have dust particles and oxygen molecules. the white light meaning all of the colors in a rainbow shines through the upper levels of the atmopshere and the blue light scatters across the entire planet. that is why our sky is blue.
