have a ____ percent chance of being heterzygous for that trait.
Will it be 0, 25, 50, 100?

Aa x Aa -- AA, Aa, aA, aa
Oh, 50%
It's not 25% because the AA and aa are not heterozygous, they are homozygous

Do a punnet square to figure this one out
Say the trait is represented by the letter 'b'
B= dominant, b=recessive
Bb x Bb
BB Bb
Bb bb
2 out of every 4 offspring in the next generation may be born heterozygous for that trait. 2/4= 50%

Definitely 50. If you do a Punnett square, you get one homozygous dominant, two heterozygous dominant, and one homozygous recessive. Therefore, it has a 50% chance of being heterozygous for the trait. Hope it helped!

TT Tt
Tt tt
Your Answer is 50% Heterozygous, 25% Homozygous TT, 25%Homozygous tt

It is 50% chance bcoz,
TT=25% (tall)
tt=25% (dwarf)
Tt=50% (intermediate) It is in heterozygous condition.

50% would be heterozygous, 25% would be homozygous dominant and the other 25% would be homozygous recessive.

b. if the gene for the trait of the parents are, say, AB, then the possible combinations are: AA AB AB BB so the answer is 1/4, or 25%.

It is definitely 50.
Just draw out a simple Punnet square. Two of the squares show heterozygotes. Two show homozygotes.

There is a 25% chance for TT, 25% chance for tt, and 50% chance for Tt.
