In order to produce a non-flying hero...
each parent must have at least one recessive allele to give (they could be heterozygous or homozygous recessive)
there is no way to figure out anything from the offspring phenotype
one parent must be homozygous recessive and the other must be homozygous dominant
one parent must be homozygous recessive, doesn't matter about the other parent
What is a trait?
an inherited physical characteristics passed from parent to offspring.
the passing of traits from parents to offspring

What is a punnett square?
A model used to show the cross of true-breeding pea plants.
A model used to determine exact genotypes of offspring.
A model used to predict possible genotypes of offspring.
None of the choices are correct.
A heterozygous tall (Tt) pea plant with a heterozygous tall (Tt) pea plant were crossed. Note: tt indicates a short plant. The punnet square is below. What are the correct ratios and percentages of the offspring's genotypes?
TT= 1/4= 25%, Tt= 1/2= 50%, tt= 1/4= 25%
Tt= 1/2= 75%, tt= 1/4= 25%
Tt= 1/2= 50%, tt= 1/2= 50%
TT= 1/2= 50%, Tt= 1/2= 50%, tt= 1/4= 25%
