The answer should be allele(s).
Alleles are alternative forms of genes. For example in eye color, there is brown eye allele that produces brown eyes or blue eye alleles that produces blue eyes.
However, note that there may be dominant or recessive alleles. Dominant alleles are always expressed, meanwhile, recessive allele is only expressed when there is no dominant allele existing.
An example is let say brown eye allele is dominant and blue eye allele is recessive. The eye gene is controlled by 2 alleles. If I had one brown eye allele and 1 blue, my eyes will be brown, because brown eye allele is dominant.
Answer:
Their function is to package DNA into structural units called nucleosomes. Histones are the main proteins in chromatin. Chromatin is a combination of DNA and protein which makes up the contents of a cell nucleus. Because DNA wraps around histones, they also play a role in gene regulation.
I hope this helped and is the right answer.

Answer:
Behavioral sciences
Explanation:
Behavioral or behavioral sciences are a set of disciplines that focus their attention on human behavior to the extent that it influences and is influenced by the attitudes, behavior and need of other people. The disciplines that are part of the behavioral sciences are: anthropology, pedagogy, political science, psychiatry, psychology, criminology and sociology. or any other behavior that varie.
A pure-breeding double-mutant (apricot, blunt) has aabb genotype, wild-type wasp has genotype AABB. If we cross them:
P: aabb x AABB
F1: all the genotypes would be AaBb
If we ten cross the F1 dihybrids with the double-mutant line:
AaBb x aabb
F2: (table)
The four phenotypes are: 1) wild-type, 2) wild type apricot-short, 3) pale orange-wild type blunt, 4) double-mutant.
The possible haploid genotypes of the gamete it received from the F1 dihybrid: AB, Ab, aB, ab. AB and ab are nonrecombinant (nonREC), like those from parents, while Ab and aB gamets are recombinant (REC) .
Explanation:
arbon dioxide is a colorless gas with a density about 53% higher than that of dry air. Carbon dioxide molecules consist of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth's atmosphere as a trace gas. The current concentration is about 0.04% by volume, having risen from pre-industrial levels of 280 ppm.
