Here are the answers to your questions:

Question 1:
The basic unit of heredity that is passed from parents to offspring is called a gene.

Question 2:
The different forms of a gene that can occupy a specific locus on a chromosome are called alleles.

Question 3:
A heterozygous genotype consists of one dominant and one recessive allele.

Question 4:
In Mendel's experiments with pea plants, the term "dominant" refers to the allele that is expressed in the phenotype of the heterozygote.

Question 5:
In a monohybrid cross of two heterozygous guinea pigs, the percentage of offspring that will be hairless (assuming hairless is recessive) will be 25%.
