in a genetics laboratory, two heterozygous tall plants (Tt) are crossed. Complete the Punnett square below. (6 points)
To complete the Punnett square, we need to consider the possible combinations of alleles from each parent. The alleles for tallness (T) are dominant over the alleles for shortness (t).
So, the possible alleles that each parent can contribute are:
Parent 1: Tt
Parent 2: Tt
To create the Punnett square, we take one allele from each parent and place them in the square corresponding to their combination:
| T | t |
-------------------
T | TT | Tt |
-------------------
T | Tt | tt |
-------------------
So, the Punnett square for crossing two heterozygous tall plants (Tt x Tt) is:
| T | t |
-------------------
T | TT | Tt |
-------------------
T | Tt | tt |
