There are giraffes that show an incomplete dominance in neck size. A giraffe with a tall neck (TT) is crossed with a giraffe with a medium neck (TS). What fraction of giraffes will
also be tall?
25%
O 75%
O 50%
100%

50%

Explanation:

(TT) Is fully tall. (TS) Is medium. So it can be assumed that (SS) is short. When forming a cross, you cross TT and TS to generate a phenotypic ratio of 1x1 or a genotypic ratio of 1 TT, 1 TS. Making it exactly split in half in 50/100.

Hope this helps!
