Dad: TtBb
Mom: ttbb
You have to use distribution for dihybrid crosses. Meaning, the first allele of each trait has a equal chance of being paired with the other allele of the other trait. So for example with Dad, I will number the traits:
T(1)t(2)B(3)b(4)
To set up the possibilities from Dad, it would be 13, 14, 23, 24: TB, Tb, tB, tb. Same idea goes for Mom, except since all alleles are the same, you only need to make one column for Mom, since if you did all 4, the other 3 would just be repeats of the 1.
Cross:
tb
TB TtBb
Tb Ttbb
tB ttBb
tb ttbb
The phenotypic ratio is 1 Tall Brown: 1 Tall Blue: 1 Short Brown: 1 Short Blue

Refined carbohydrates tend to be much in lower in
fiber and vitamins than whole grains. These are complex carbs that have had fiber removed from them
leaving reproduce simple carbohydrates. These are rapidly absorbed causing a
blood sugar increase, which is followed by some crash. During the milling
process, the germ and bran is peeled and the grain's endosperm is crushed. The
final product becomes easier to gnaw and digest. The main reason manufacturers
process the grain is to lengthen shell life.
Answer:
Cork is a protective tissue that separates the living cells of the plant from the outside environment. The formation of cork in the periderm is the result of the activity of a secondary meristem, the cork cambium, or phellogen.
