Answer: False
The variations in expression depends on how genes code for proteins
that would specify whether it will be dominant or recessive allele. Within a population, there may be a number of
alleles for a given gene and these differences
can cause variations in the protein that is produced. The change in protein
expression affect traits due to the variations in protein activity or
expression that produce different phenotypes.
<span>Moreover, individuals that have copies of
different alleles are known as heterozygous
and individuals that have two copies of the same
allele are referred to a homozygous. The expression patterns observed in
inheritance will depend on whether the allele is found on an autosomal
chromosome or a sex chromosome, and on whether the allele is dominant or recessive.</span>
<span>A deletion has occurred in the chromosomal structure. This is because the gene represented by d has been removed from the list of genes after the breakage has occurred.</span>
Answer:
Symbiosis or Mutualism: When two species live together in a close association that is helpful to both species, the relationship is known as symbiosis. The oxpecker bird and the rhinoceros exhibit this relationship. The oxpecker receives protection and obtains food from the ticks and other pests infesting the rhino’s skin.

Fermentation is the process by which a carbohydrate molecule is broken down into alcohol and carbon dioxide in the absence of oxygen. During this process, two molecules of ATP is produced. In the absence of oxygen, pyruvate formed from glycolysis will undergo fermentation process. During the process of fermentation, NADH from glycolysis will be converted back to NAD+. This is necessary in order for glycolysis to continue. Thus, fermentation regenerate more NAD+ and only a few molecule of ATP.
