Grade 7 gradeScience subjectFree quiz

Grade 7 heredity connects DNA, genes, and alleles to traits you can and cannot see. Students separate inherited traits from acquired ones, use dominant and recessive language carefully, and read a Punnett square as a probability. Environment can still shape how a genotype appears as a phenotype.

What you practice

These are the Grade 7 Genetics & Heredity skills this quiz is built around.

  • Relate DNA, genes, and alleles, and distinguish genotype from phenotype.
  • Use a Punnett square to find genotypic and phenotypic probabilities for a single-gene cross.
  • Tell inherited traits from acquired traits and note that environment can affect expression.

A useful tip

A Punnett square gives expected probabilities, not a promise about one family. Four offspring do not have to match a 1:2:1 count just because that ratio is expected.
