In a flowering plant, tall (t) is dominant to short (t), and blue flowers (b) is dominant to white flowers (b). a tall plant with white flowers (ttbb) is crossed with a short plant with blue flowers (ttbb). what is the chance that the offspring will be short with white flowers?

25%

Explanation:

Following a cross between Ttbb and ttBb, the resulting offspring would be:

TtbB , TtbB , Ttbb , Ttbb , ttbB , ttbB , ttbb , ttbb , TtbB , TtbB , Ttbb , Ttbb , ttbB , ttbB , ttbb , ttbb

To have a clearer idea, see the attached image.

Of the 16 possible combinations from this dihybrid cross, there will be:

4 tall plants with blue flowers

4 tall plants with white flowers

4 short plants with blue flowers

4 short plants with white flowers

There are 4 possible genotypic recombinations that would yield short plants with white flowers out of a possible 16, so the chance that the offspring will be short with white flowers would be 4/16 which is 1/4 or 25%

Hope this helps

Ui do not known man just trying to answer my first question

Ithink option a is correct because you cannot donate a different blood group than yours because it won't match.option a says betsy can donate to mark. they have the same blood group so donation can happen.
