In a large population of randomly breeding organisms, the frequency of a recessive allele is initially 0.3. there is no migration and no selection. humans enter this ecosystem and selectively hunt individuals showing the dominant trait. when the gene frequency is reexamined at the end of the year,

The frequency of both  homozygous and heterozygous dominant species will start reducing and the frequency of homozygous recessive species will start increasing

Explanation:

Given-

Initial frequency of recessive allele is

Since there is no  migration and no selection the population follows Hardy's Weinberg's equilibrium.

Thus , the frequency of dominant allele as per Hardy Weinberg's equation would be -

Humans enter this ecosystem and selectively hunt individuals showing the dominant trait. This means that they would be killing both homozygous and heterozygous dominant species.

Therefore, the  frequency of both  homozygous and heterozygous dominant species will start reducing and the frequency of homozygous recessive species will start increasing.

explanation:

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
