Answer:
An organism's genotype is the set of genes that it carries. However, since an organism's genotype generally affects its phenotype, the phenotypes that make up the population are also likely to change.
Explanation:
For example, differences in the genotypes can produce different phenotypes.
The conditioned reinforcers known as tokens can be accumulated and traded for different reinforcers.
Any two suitable examples, such as a compliment, an invitation to dinner, the presence of a loved one, or a warm greeting are all suitable examples. These are all conditioned reinforcers since they are connected to stronger reinforcers. They cannot be accumulated and swapped for different backup reinforcers, hence they cannot be considered tokens.
What is backup reinforcer?
Backup reinforce is a reinforcer that serves as the foundation for a conditioned reinforcer. It is a reinforcer in a token system for which tokens can be traded in order to keep their reinforcing properties. For instance, poker chips can be converted into cash at the conclusion of a game of poker. The money serves as a secondary reinforcer in this situation. It is allowed to use any two relevant examples.

Mitosis begins with prophase, during which chromosomes recruit condensin and begin to undergo a condensation process that will continue until metaphase. In most species, cohesin is largely removed from the arms of the sister chromatids during prophase, allowing the individual sister chromatids to be resolved.
Prometaphase begins with the abrupt fragmentation of the nuclear envelope into many small vesicles that will eventually be divided between the future daughter cells. The breakdown of the nuclear membrane is an essential step for spindle assembly.
Next, chromosomes assume their most compacted state during metaphase, when the centromeres of all the cell's chromosomes line up at the equator of the spindle. Metaphase is particularly useful in cytogenetics, because chromosomes can be most easily visualized at this stage. Furthermore, cells can be experimentally arrested at metaphase with mitotic poisons such as colchicine.
The progression of cells from metaphase into anaphase is marked by the abrupt separation of sister chromatids. A major reason for chromatid separation is the precipitous degradation of the cohesin molecules joining the sister chromatids by the protease separase.
Mitosis ends with telophase, or the stage at which the chromosomes reach the poles. The nuclear membrane then reforms, and the chromosomes begin to decondense into their interphase conformations. Telophase is followed by cytokinesis, or the division of the cytoplasm into two daughter cells. The daughter cells that result from this process have identical genetic compositions.
Yes, heterozygous recessive is a thing it is a particular gene that has identical alleles its has the same letters for a dominant trait it's (XX) and for a recessive is lowercase (xx) just remember the alphabet the D is first then the R so D is capital and R is lower case
