Step-by-step explanation:
Remember that when heterozygous traits are crossed, the gametes would be one homozygous dominant gamete, two heterozygous gametes, and one homozygous recessive. Thus, we obtain the following results:
TR, Tr, tR, and tr.
Notice that in this case, TR is the homozygous dominant gamete, Tr, tR are the heterogygous gametes and tr is the homozygous recessive gamete.
we can conclude that the correct answer is:
Answer:
TR, Tr, tR, and tr.
