myrzilka [38]

Answer:

The correct answer is - DNA --> RNA --> amino acid --> protein --> phenotype.

1.  Carolus had expanded and developed a classification system of all species and types of organisms that were known in the 18th century. " A French naturalist names Lamarck" suggested that all the known organisms evolved toward perfection and complexity.
 
2. Lyell inferred the same changes happened in the past. Uniformitarianism merges and combined Hutton's ideas of gradual with Lyell's ideas and observations that changes a constant rate.

3. Gradualism is a theory or view of speciation that proceeds small, cumulative steps when time goes on rather than by major changes or others.

A gene can have many alleles. Why is it that any given person only carries two copies of each allele
Katyanochek1 [597]
Since diploid organisms have two copies of each chromosome, they have two of each gene. Since genes come in more than one version, an organism can have two of the same alleles of a gene, or two different alleles. This is important because alleles can be dominant, recessive, or codominant to each other.
