Non Mendelian Genetics

In this problem, we are dealing with a Mendelian inheritance pattern, where the trait of plant height (tall vs. short) is determined by the alleles "T" and "t". The "T" allele is dominant for tall plants, while "t" is recessive for short plants. When two heterozygous plants (Tt) are crossed, the possible genotypes of the offspring are as follows:

1. The genotype of the parents is .

2. Using a Punnett square to determine the offspring's genotypes: The possible genotypes of the offspring are: - (homozygous dominant, tall) - (heterozygous, tall) - (homozygous recessive, short)

3. The probability of obtaining a short plant, which must have the genotype , is 1 out of 4 (or ). Thus, the probability of obtaining a short plant is .
