What is a monohybrid cross?
Think about the number of traits involved.
What does a Punnett square help you predict?
Consider what you are trying to find out about the offspring.
What is a monohybrid cross?
Think about the focus of the cross.
True or False: A Punnett square can predict phenotype ratios.
Recall what a Punnett square is used for.
If two heterozygous plants (Tt) are crossed, what is the probability that an offspring will be homozygous recessive (tt)?
Consider the total combinations in the Punnett square.
A plant shows a trait for tallness (T), but when crossed with a recessive plant (t), the offspring yield both tall and short plants. How would you determine the parent's genotype?
Recall how dominance works and what it means for offspring to show the recessive trait.
