Answer:
If two heterozygous tall pea plants are crossed, the probability of their offspring being tall is 75%
Answer:
Tt - 2/4 = 1/2 or 50% Heterozygous TALL
tt - 2/4 = 1/2 or 50% Homozygous Dwarf
Explanation:
So let's make a Punnett for this so you can see what the outcome is yourself:
Tall is <u>dominant</u> - T
Dwarf is <u>recessive</u> - t
Heterozygous means that they have one of each allele. The genotype of one parent would be then Tt.
***It is heterozygous tall because Tall is a dominant trait so if it is accompanied by the recessive trait dwarf, then the Tall allele would mask it.
The other parent is a dwarf plant. The genotype would then be tt.
*** Now for a recessive trait to appear, it should not have a dominant trait mixed with it, which could mask it. The result then is homozygous recessive or homozygous Dwarf.
So now that we know the genotypes of the parent plants, we can put it into a Punnet:
t t
T Tt Tt
t tt tt
As you can see, out of the 4 outcomes we have:
Tt - 2/4 = 1/2 or 50% Heterozygous TALL
tt - 2/4 = 1/2 or 50% Homozygous Dwarf
They might go extinct if they can't keep up with the competition
