Grade 9 gradeScience subjectFree quiz

Grade 9 genetics extends Mendelian ratios to incomplete dominance, codominance, sex-linked traits, and pedigrees. Students still use Punnett squares, but they also read a family chart and distinguish genotype from phenotype when environment plays a role. Probability language stays attached to a specific cross.

What you practice

These are the Grade 9 Genetics & Biotechnology skills this quiz is built around.

Solve a monohybrid or sex-linked Punnett square for genotypic and phenotypic ratios.
Interpret a pedigree for an autosomal or X-linked pattern.
Describe incomplete dominance or codominance as distinct from simple dominant-recessive.

A useful tip

In incomplete dominance, heterozygotes show a blended phenotype, as in red × white flowers yielding pink. Codominance shows both alleles, as in AB blood type, rather than a blend.
