In a flowering plant species, if red flower color (R) is dominant over white flower color (r), what are the possible genotypes for a red-flowering plant?

Back

The possible genotypes are RR or Rr.

Front

What is a Punnett square used for?

Back

A Punnett square is used to predict the genotypes of offspring from parental genotypes.

Front

Define genotype.

Back

Genotype is the genetic makeup of an organism, represented by alleles.

Front

What is the difference between homozygous and heterozygous?

Back

Homozygous means having two identical alleles for a trait, while heterozygous means having two different alleles.

Front

If a plant has the genotype Tt, what is its phenotype?

Back

The phenotype is tall, since T (tall) is dominant.
