Answer:
A dominant allele is a variation of a gene that will produce a certain phenotype, even in the presence of other alleles. A dominant allele typically encodes for a functioning protein. ... When a dominant allele is completely dominant over another allele, the other allele is known as recessive.
A recessive allele is a variety of genetic code that does not create a phenotype if a dominant allele is present. ... A heterozygous individual will appear the same as a homozygous dominant individual. This means that an organisms with two dominant alleles appear the same as an organism with only one functioning allele.
The chemical formula would be
CTGA or any of the combinations of the four nitrogenous bases
The nucleotide is made up of four bases which makes it a tetranucleotide and the arrangement of each bases create a linear geometry.
Answer:
it is the change in one or more genes
I'd say zoology.
Zoology is the study of animals, generally speaking, and since birds are animals, the study of these fall into the field zoology. The study of birds though, is called ornithology.
