Question

chromosome number
body cells contain a full set of chromosomes from each
parent. these ____________ chromosomes
contain matching gene sequences. since body cells
contain both sets from each parent, they are called
__________ (2n). __________, or sex cells, have
only one set of chromosomes and are
called ____________ (n).

Explanation:

• Homologous chromosomes are pairs of chromosomes (one from each parent) that have the same gene sequences.
• Diploid cells (\(2N\)) have two sets of chromosomes (one from each parent), which is the case for body cells.
• Gametes (sex cells like sperm and egg) are haploid (\(N\)) as they have only one set of chromosomes.

Answer:

1. homologous
2. diploid
3. Gametes
4. haploid
