Question

in pea plants, the trait of being tall (t) is dominant to to being short (t). cross a heterozygous tall plant with a short plant. what is the phenotype ratio of the offspring?
○ 4 tt
○ 2 tall: 2 short
○ 2 tt: 2 tt
○ 4 tall

Explanation:

Step1: Identify parent genotypes

Heterozygous tall plant: $Tt$; Short plant: $tt$

Step2: Set up Punnett square

	$T$	$t$
$t$	$Tt$	$tt$

Step3: Determine offspring phenotypes

$Tt$ = tall (2 individuals); $tt$ = short (2 individuals)

Step4: Calculate phenotype ratio

Ratio of tall to short: $2:2$ (simplifies to $1:1$, but matches the option format)

Answer:

2 Tall: 2 Short
