small sections of chromosomes that code for proteins that make traits

• Cell wall

• nucleus

• genetic engineering

• genes

Identical twins and clippings from plants that grow into new plants are examples of .... because DNA is identical to siblings

• clones

• mutations

• autosomal chromosomes

• sex chromosomes

Changes in genes or chromosomes are called...

• clones

• autosomal chromosomes

• sex cells

• mutations

This is a chart that helps scientists, physicians and families track traits in families

• mutation

• pedigree

• punnett square

• artificial selection

gametes, or sperm and egg are also called...

• sex chromosomes

• autosomal chromosomes

• sex cells

• clones

These are most (self-body) chromosomes, not sex chromosomes
