NGSS.HS-LS1-1

A phenotype describes the genetic make-up of an individual.

• True

• False

When Mendel crossed true-breeding tall plants (TT) with true-breeding short plants (tt), all of the offspring were tall because...

• The allele for tall plants is recessive.

• The allele for short plants is dominant.

• The allele for tall plants is dominant

What is the relationship between phenotype and genotype?

• The phenotype determines the genotype.

• The genotype determines the phenotype.

• There is no relationship between phenotype and genotype.
