The inheritance of biological characteristics is determined by individual units called ​ (a)   , which are passed from parents to offspring. Where two or more ​ (b)   of the gene for a single trait exist, some alleles may be​ (c)   and others may be recessive.

• genes

• alleles

• dominant

• gametes

Answer explanation

The inheritance of biological characteristics is determined by individual units called genes, which are passed from parents to offspring. Where two or more alleles of the gene for a single trait exist, some alleles may be dominant and others may be recessive.
