What is a trait?
What is a specific characteristic or feature exhibited by an organism?

Why is the word homologous used to describe chromosome pairs, rather than the word identical?
Homologous chromosomes are pairs of chromosomes that appear similar, in terms of length and other characteristics but they are not identical to each other.

What is haploid?
Haploid - half the number of chromosomes

What is the differences between dominant and recessive?
Dominant - the form of a trait that always appears when an individual has an allele for it. Recessive - the form of a trait that only appears when an individual has two alleles for it.
