Answer:
In biology, evolution is the change in the inherited traits of a population from generation to generation. These traits are the expression of genes that are copied and passed on to offspring during reproduction. ... Genetic drift arises from the role chance plays in whether a given individual will survive and reproduce.
Heredity - This is the passing on of traits from parents to their offspring either through sexual reproduction or asexual reproduction.

The stage of respiration that immediately follows the process duplicated is the Kreb's cycle.
<h3>What is the Kreb's cycle?</h3>
The Kreb's cycle is a cycle which oxidizes one molecule of acetylCoA to two carbon dioxide molecules per cycle with the production of the reducing equivalents NADH and FADH2 for the electron transport chain,.
The Kreb's cycle consists of eight enzymatic steps as follows:
- Condensation of acetyl CoA with oxaloacetate to form citrate catalyzed by citrate synthase.
- Conversion of citrate is converted to its isomer, isocitrate catalyzed by aconitase.
- Dehydrogenation and decarboxylation of isocitrate to form
It Is called, a mirror image or reflection.
Answer:
True breeding
Explanation:
One of the main reasons behind the success of Mendel's experiments was that he started the experiments with pea varieties that were true breeding. It is important to understand what a true breeding variety is, it is a plant or organism that is homozygous for a certain trait, in Mendel's case, the pea varieties were homozygous for seven traits, which are : seed coat tint, pod shape, seed shape, flower color, flower location, unripe pod color, and plant height. It means that the varieties contained two similar alleles of genes for these traits in pea plant varieties he chose. Due to the true breeding nature of these traits, the parent plants produced offspring that showed the phenotype just like their parents.
For example:
Here is a cross between plant with yellow flower with another plant containing yellow flower.Suppose allele for yellow is Y and allele for green is y. Let us see what happens in this breeding:
Parents: YY X YY
Offspring: YY
Again cross between offspring: YY X YY
Offspring: YY
This is true breeding in which offspring contain phenotype of parent in many successive generations.
Hope it helps!
