Question

1. red roses are dominant to white roses, and tall are dominant to short. cross a flower that is homozygous red and tall with a flower that is white and heterozygous tall. what will be the possible genotypes and phenotypes of the offspring? show your work as a punnett square and write your answers as a phenotypic ratio.10. use the punnett square that you created in #9 to answer the following questions:a. what percentage of the offspring will be red and short?$\frac{0}{16} cdot 100% = 0%$

Explanation:

Step1: Define allele symbols

Let $R$ = red (dominant), $r$ = white (recessive); $T$ = tall (dominant), $t$ = short (recessive)

Step2: Identify parent genotypes

Homozygous red tall: $RRTT$; gametes = $RT$ (all)
White heterozygous tall: $rrTt$; gametes = $rT, rt$

Step3: Correct Punnett square setup

	$RT$	$RT$	$RT$	$RT$
$rt$	$RrTt$	$RrTt$	$RrTt$	$RrTt$

Step4: Analyze genotypes/phenotypes

• Genotypes: $RrTT$, $RrTt$
• Phenotypes: All red tall (since $R$ is dominant, $T$ is dominant)

Step5: Solve part 10a

Red short requires $R\_tt$. No offspring have $tt$, so percentage = $\frac{0}{16} \times 100\% = 0\%$

Answer:

For question 9:

• Possible genotypes: $RrTT$, $RrTt$
• Phenotypic ratio: 1 (red tall) : 0 (all other phenotypes)

For question 10a:

0%
