Question

Draw a Punnett square of an Ss x ss cross. The S allele codes for long stems in pea plants and the s allele codes for short stems. If S is dominant to s, what percentage of the offspring would you expect to have each phenotype?

Answer 1

Answer:

Hope this helps

Answer 2

The punnet square is used to predict phenotypes.

50% of the offsprings would have long stems, while the other 50% would have short stems.

See attachment for the SS vs ss cross

From the attachment, we have the following observations

$n = 4$ --- number of squares

$Ss =2$

$ss = 2$

Because S is dominant over s;we can write Ss as S.

So, we have:

$n = 4$

$S = 2$

$s =2$

The percentage of each offspring calculated as follows is:

$S\% = \frac{S}{n} \times 100\%$

$S\% = \frac{2}{4} \times 100\%$

$S\% = 0.5 \times 100\%$

$S\% = 50\%$

$s\% = \frac{s}{n} \times 100\%$

$s\% = \frac{2}{4} \times 100\%$

$s\% = 0.5 \times 100\%$

$s\% = 50\%$

Hence, 50% of the offsprings would have long stems, while the other 50% would have short stems.
