A genomic researcher is analyzing the genome of different species of raptors. She finds that a particular sequence in the Bald E

agle genome is identical to a sequence found in the Red Tailed Hawk, while most other sequences in those two genomes differ at many nucleotides. (The most recent common ancestor between Bald Eagles and Red Tailed Hawks was approximately 6.8 million years ago, which is plenty of time for mutation to generate DNA sequence variation.) Which of the following could explain the identical sequence in these otherwise differing genomes?
a. The sequence encodes a protein critical for the production of feather color.
b. The sequence encodes a gene that is critical for life and cannot be easily mutated while retaining function.
c. The sequence is from an intron of a gene that encodes a protein in connective tissue.
d. None of these

Answer:

d. None of these  

Explanation:

Probably the identical sequence found in both species<em> </em>is an<em> ultraconserved sequence. </em>

An <u>ultraconserved element</u> is a particular DNI sequence that remains exactly the same through evolution, with almost no modification, and that is shared by at least two completely different species.

These ultraconserved DNI portions seem to be highly essential for life. However, their function could not be determined yet. Most of them do not codify for proteins, but they could play a significant role in gene regulation.

It is suggested that these sequences are so significant for life that only a small change would compromise the organism´s aptitude.

What are three environmental factors that can influence plant phenotypes
sergij07 [2.7K]

The genotype describes the complete set of genes inherited by an individual, and the phenotype describes all aspects of the individual's morphology, physiology, behavior, and ecological relations. Light, water, temperature, soil structure are the environmental factors which influence the plant phenotype most. The growth is a very sensitive phenotypic trait that quickly responds to any sub-optimal environment. However, many more physiological responses occur that turn out in phenotypes that can be measured with non-invasive technology.

two parents with normal phenotypes have a daughter who genetically inherited a disorder. Explain how this is possible.
sukhopar [10]

Answer:

              Phenotype is physical appearance of the individual while genotype is the genetic makeup of the individual.

Explanation:

                      Two parents having normal phenotype but effected individual is due to the parents may be Carrier for the particular deseis and the gene responsible for the desies may be in recessive form and the parents are not effected.  The gene is not present in dominant form and can not show its effect but the parents are not effected and the daughter may be affected by certain desiese.

d. Deciduous trees such as most pines do not lose their leaves/foliage in winter.

Explanation:

Yes, Rachel Carson is the founder of the modern environmental movement as well as author of Silent Spring. She was an American marine biologist, author, and conservationist which started the modern environmental movement in order to save the environment form pollution. Yes, the Deciduous trees such as most pines do not lose their leaves/foliage in winter, they only lose those leaves that are too old. They are considered as evergreen plants.
