heredity beginnings (part 1) test

A mother and father have two daughters. The daughters have some similar and some different physical features. Which statement BEST explains why the girls’ physical appearance includes both similar and different features?

• one daughter received fewer genes than the other

• each daughter received a different number of genes from each parent

• the daughters received a random set of genes from both parents

• one daughter received all her genes from her father and the other daughter received all her genes from her mother

Which statement is true about DNA?

• DNA is an exact copy from parent to offspring

• DNA is not necessary for an organism to reproduce

• DNA contains genes that determine specific traits for an organism

• Organisms create their own DNA sequence that is not like their parents

The genetic code is determined by:

• the sequence of phosphates in DNA

• the sequence of sugars in DNA

• the sequence of nitrogen bases in DNA

• the sequence of acids in DNA
