The colour of a mouses fir is determined by a single gene. different versions of a gene are known as alleles.

Explain how a gene codes for a characteristic?

From the assertion above, every genotype is made up of a pair of allele which one is donated from a parent to form a genotype. The dominant gene determines the characteristics that the offspring would exude.

Explanation:

if parent A donates an allele T and parent B donates an allele t, both parents now has Tt has a pair of allele but the ones from parent A dominates which is T over t, then such offspring exudes tallness which is a gene inherited from one of the parents

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
