Question

tall plants (t) are dominant over short plants (t). in a cross between dominant and recessive homozygous parents (tt x tt), 25% of the offspring should be homozygous recessive. true false

Explanation:

Step1: Determine parental gametes

The homozygous dominant parent (TT) can only produce T gametes, and the homozygous recessive parent (tt) can only produce t gametes.

Step2: Use Punnett - square analysis

When we cross TT and tt using a Punnett - square, all of the offspring will have the genotype Tt. There will be 0% homozygous recessive (tt) offspring.

Answer:

FALSE
