<span>The correct option is A. Founder's effect is the reduced genetic variability that occur as a result of population production from a small number of colonizing parents. The founder's effects is one of the ways by which nature can randomly produce new species from existing population.</span>

in chickens, the allele for black feathers is co-dominant with the allele for white feathers. black-feathered and white-feathere
Vladimir79 [104]

In chickens, the black wing allele is co-dominant with the white wing allele. Black and white birds are homozygous for the black (B) allele or the white (W) allele.

In genetics the terms, codominance refers to the pattern of inheritance in which the two versions (alleles) of the same gene are being expressed separately to produce the different traits in the individual. In perfect dominance, only the one allele of the genotype is also present in the phenotype. In codominant cases, both the alleles of the genotype are present in the phenotype. In the case of the imperfect dominance, the phenotype shows the mixture of genotypic alleles. In the genetics terms, codominance refers to the pattern of inheritance in which the two versions (alleles) of the same gene are expressed and separately to produce the different traits in the individual.

Which of these serves as a reference for comparison during a scientific investigation?
icang [17]
That would be C. The control group is the group where no variable has been changed for it and it’s how something normally would be.

For example if we’re experimenting the effect of excess water on plant growth the plant getting normal amount of water is the control group and the plant getting excess water is the test group(or groups in most cases there is more than one).

You can use the growth of the control plant as a reference of how the growth of the other plant has been affected(wether it has been increased or decreased or stayed the same)

Any smaller forms that held to a star like shape are adolescents. The shrimp pertaining to a more acceptable 'shrimp' shape is a matured adult. Brine shrimp have certain stages of maturity.

What is produced during transcription
Westkost [7]
During transcription, RNA molecules re produced, mRNA specifically. Transcription in protein synthesis is when the mRNA is created using the template of DNA. It is the process of transcribing DNA to mRNA which is catalyzed by RNA polymerase. Transcription encompasses manufacturing, splicing, and adding of caps and tales of the mRNA. All of these happen in the nucleus of the cell. <span>Replication, transcription, and translation are three different terms. Replication means duplication of DNA. Transcription is the multiplication or duplication of genetic information into mRNA and translation is protein production through activities of ribosome.
