California Content Standards: Grade 7
2. A typical cell of any organism contains genetic instructions that specify its traits.
Those traits may be modified by environmental influences. As a basis for understanding this concept:
a. Students know the differences between the life cycles and reproduction methods of sexual and asexual
b. Students know sexual reproduction produces offspring that inherit half their genes from each parent.
c. Students know an inherited trait can be determined by one or more genes.
know plant and animal cells contain many thousands of different
genes and typically have two copies of every gene. The two copies (or alleles) of the gene may or may not be identical, and
one may be dominant in determining the phenotype while the other is recessive.
know DNA (deoxyribonucleic acid) is the genetic material of
living organisms and is located in the chromosomes of each cell.
