• Human Genome

• Gene Therapy

• Meiosis

• Genetics

When a cell contains only one set of chromosomes.

• diploid

• haploid

• zygote

__________________ is the study of how traits are passed on, or inherited.

• Pedigrees

• Transformation

• Gene Therapy

• Genetics

Chromosomes that are paired together during meiosis and carry the same set of genes are called

• homologous alleles

• homologous genes

• homologous zygotes

• homologous chromosomes

In which phase does the DNA copy itself?

• interphase

• metaphase

• anaphase

• telophase

If 2n = 48 for a particular cell, then the chromosome number in each cell after meiosis would be
