. Limb bones within unrelated animals that have the same basic structures are considereda. vestigial structures.
b. homologous structures.
c. embryological.
d. analogous structures.

Answers

When you have unrelated animals in biology which have limbs that have the same basic structure we consider these things to be homologus. As the first poster noted, an example is a wing of a bird or a hand of a human. When we're talking about analogous structures, we're talking about things which perform the same function yet don't have the same structure.

in certain species of roses, white roses and red roses are incompletely dominant to each other. when a red rose and a white rose are crossed, a pink rose is produced. what is the probability of producing a white rose when a red rose is crossed with a pink rose

Answers

The answer is 0%.

If white and red roses are incompletely dominant, the phenotypes are as following:
AA - red roses
AB - pink roses
BB - white roses

So, a cross between a red (AA) and a pink rose (AB) will result in only red or pink roses:
Parents: AA x AB
Offspring: AA AA AB AB

If white and red roses are incompletely dominant, the phenotypes are as following:

AA - red roses

AB - pink roses

BB - white roses

So, a cross between a red (AA) and a pink rose (AB) will result in only red or pink roses:
