Answer:

The correct answer would be B) there are no similarities in the embryos of all four groups.

There are similarities in various stages of the embryonic development of different species. They look very similar in the early stages of development. The ancestors of the different animals are same and this implies that they are related.

For example, the embryo of both human and fish has gill slit but in the later stages, the gill slit of human embryo disappears. The difference in later stages shows the evolution of different traits but the beginning of creatures are same.

It is why comparative embryology is also used to provide evidence of evolution.

Thus, the development of four vertebrates and suggests all of the following EXCEPT there are no similarities in the embryos of all four groups.

In a plant called jimsonweed, flowers can be white or purple. A jimsonweed plant with white flowers is crossed with a jimsonweed

STALIN [3.7K]

Answer:

Although statements are not given in the question, we could make the most possible deduction as follows:

The allele for purple flowers is dominant whereas allele for white flowers is recessive.

Explanation:

According to the question,

Purple flower plant was crossed with white flower plant.
All offsprings have purple flowers.

Here we have one possibility that both parents were homozygous but in their own traits. Purple flower plants were "PP" and white flower plants were "pp" So, the first progeny (direct offsprings) would have "Pp". So, as per considerations, purple is dominant allele which will mask the recessive allele thus defining the color of all offsprings as purple. However, further cross of their generation will definitely end up into purple and white flowers (3:1) but this condition is not mentioned in the statement.
