Final answer:
Yes, two homozygous tall pea plants could produce short pea plants.
Step-by-step explanation:
The answer is d. Yes, two homozygous tall pea plants could produce short pea plants. While tall pea plants are dominant over short pea plants, it is still possible to produce short pea plants by crossing two homozygous tall plants. In this case, both parents have the genotype TT, meaning they possess two dominant tall alleles. However, they can still pass on the recessive short allele to their offspring.
