Question

A tall pea plant is crossed with a short pea plant. All of the offspring that are produced are tall. Two of these tall offspring are crossed. The punnett squar for this second cross is shown.
what can be concluded from this cross.
A.Tall pea plant can only produce tall offspring.
B.Tall pea plants can only prouduce short offspring.
C.Tall pea plants can create tall,medium and. even short offspring.
D.Tall pe plants can carry the short trait and create some tall and short offspring.

Answer 1

Based on the information provided, we can deduce that tall pea plants can carry the recessive short trait, as evidenced by the first generation producing only tall offspring when a tall plant is crossed with a short plant. However, when two tall offspring (which could be heterozygous for the tall trait) are crossed, there is a possibility of producing both tall and short offspring in the next generation.

Thus, the correct conclusion from the options given is:

**D. Tall pea plants can carry the short trait and create some tall and short offspring.**

This conclusion aligns with the principles of Mendelian genetics, where tall (T) is dominant, and short (t) is recessive. If the tall offspring are heterozygous (Tt), crossing them may result in a combination of genotypes (TT, Tt, tt), leading to some offspring being short.
