Research and identify a vestigial structure of an organism of your choosing.
Mariana [72]

Answer:

The one of best example would be appendix in humans.

Explanation:

In the past, the appendix may have helped in the digestion of the plants by producing mucus and prevent any type of infection. Plants with a high content of cellulose are digested with the help of the appendix as reported.

It is not a part of the human digestive system and considers as a vestigial organ. Vestigial organs are the organs that are present in an organism with no particular function and their removal will not lead to any harm. Humans do not need it because our digestive system is more efficient and works better in the first stages of digestion than they used to.

Thus, the correct answer is - appendix in humans.

Answer:

The correct answer is : The dominant form of the trait shows.

Explanation:

In simple dominance, the attribute related to the prevailing or dominant allele is communicated while the character related to the latent or recessive allele is persecuted or masked. For instance –  

Taking a bloom where the dominant allele attribute is red shading and the recessive allele characteristic is white shading. At the point when a posterity of this bloom is created containing one prevailing or dominant allele and one passive allele, its shade would be red simply because just the predominant allele communicates its characteristic.  

Thus, the right answer is: The dominant form of the trait shows.
