Question

7.4. create a punnett square to predict the phenotype of offspring from parents with a known genotype both for single genes and for two independent genes.
in pea plants, the tall allele (t) is dominant to the short allele (t) and the yellow pea allele (y) is dominant to the green pea allele (y). in a cross between a ttyy pea and a ttyy pea, what are the odds that the offspring will be tall and have green peas?
1/2 1/4 1/8 1/16

Explanation:

Step1: Determine gametes

For \(TTYy\) plant: \(TY\) and \(Ty\) gametes.
For \(ttyy\) plant: \(ty\) gamete.

Step2: Create Punnett square

	\(TY\)	\(Ty\)

Step3: Analyze phenotypes

\(TtYy\) - tall, yellow; \(Ttyy\) - tall, green.
Total offspring = 2.
Number of tall - green (\(Ttyy\)) = 1.

Answer:

\(\frac{1}{2}\)
