Question

Tall (T) pea plants are dominant over short (t) pea plants.  What is the probability of getting 3 tall and 4 short pea plants from a cross between 2 heterozygous tall plants. (report to three nonzero digits.)

Expert Solution
Step 1

Law of dominance:-

This law indicates that in a heterozygous condition, the dominant allele is the one whose characters are expressed over the other allele, and the dominant characters are the ones whose characters are expressed over the other allele. Dominant characters are the characters that occur in the F1 generation. In the F2 generation, recessive traits appear.
