Question

In pea plants, the gene for the color of the seed has two alleles. In the following Punnett square shown below, the dominant allele (Y) represents yellow and the recessive allele (y) represents green.



Based on the Punnett square, what percentage of offspring would be expected to have green seeds?

0%
25%
50%
100%

Answer 1

Am I right with D?

Answer 2

@az

Answer 3

Its not C

Answer 4

Y is for yellow and it's dominant

which means that if you have even 1 Y so either Yy or 2 Y's so YY
you would have yellow seeds

y is for green and it's recessive and to get that, you need to have yy

if you had a Y with the y
then the dominant yellow would take over and it would just be yellow

Answer 5

okay, so am i right with D?

Answer 6

No

Look at the Punnett square

we have

YY
YY
Yy
Yy

what colors are those going to be?

Answer 7

Yy is green right?

Answer 8

remember what I said

Y is dominant and is for yellow
y is recessive and is for green

Yellow will be when you have YY or Yy
Green will be when you have yy

Answer 9

Okay, so 0%
