The answer is nucleic acid. Every nucleic acid is composed by a base, a sugar and a phosphate group. And they can form DNA or RNA by combining together.
<span>Mitosis is Asexual reproduction. It promotes genetic consistency because all offspring are exactly identical to the parent, unlike meiosis where homologous chromosomes are randomly dispersed between four daughter cells. organisms that only reproduce asexually are at a disadvantage because all organisms in their population are identical so if there were to be a major environmental change, they would have less of a chance of survival compared to a population of sexually reproducing organisms that are all genetically different.</span>
Answer:
A cross between two pure breeding tall (TT) and dwarf (tt) parent plants produce uniform F
Explanation:
generation of dominant individuals (Tt).
According to the law of dominance, a trait is represented by two contrasting factors of a gene in a heterozygous individual; the allele/factor that can express itself in a heterozygous individual is called as a dominant trait. Another factor whose effect is masked by the presence of a dominant factor is called a recessive factor. The recessive factor, t, is present in F
hybrids but its expression is masked by the factor for a dominant trait, T.
Answer:
A mutation is a change in a genetic sequence. Mutations include changes as small as the substitution of a single DNA building block, or nucleotide base, with another nucleotide base. Meanwhile, larger mutations can affect many genes on a chromosome. ... Other mutations result in abnormal protein products.
