Answer: Option D " all of the above "
Explanation: DNA can be a great source of information when used as a forensic evidence. This technique has many advantages and disadvantages when used as a source of information in case of crime.
Identical twins: There are some common fragments of DNA that is same in identical twins so it can be a difficulty in deciding the criminal.
Not enough of a sample: DNA should be present in a detectable amount to be used an sample for evidence, less than this detectable amount is a waste and cannot be used as a sample for evidence.
Contaminated and degraded sample: If the sample of DNA is contaminated or degraded then the result might be incorrect and might not be used as a sample for forensic evidence.
Hence, the correct answers are all of the above.
False
The genotype of an organism does not constitute its observable characteristics but rather its phenotype. A genotype of an organism is the genetic makeup of an organism while the phenotype is the visible characteristics.
It is, however, significant to understand that the phenotype of an organism is as a result of the interaction between the genotype and the environment.
Answer:
Algae is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping, including species from multiple distinct clades. Included organisms range from unicellular microalgae, such as Chlorella and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga which may grow up to 50 m in length. Most are aquatic and autotrophic and lack many of the distinct cell and tissue types, such as stomata, xylem and phloem, which are found in land plants.
Explanation:
'Im different"
Answer:
B. cv+cv w+w
Explanation:
Fruit flies have a special nomenclature to write the genotype of individuals.
- If the mutation is recessive, you have to write it with lowercase letter(s).
- If the mutation is dominant, you have to write it with capital letter(s).
- Wild-type alleles are indicated with a superscript plus (+).
In this problem, both crossveinless (cv) and white (w) mutations are recessive.
<u>For that reason, a heterozygous individual's genotype for both genes will be written as:</u>
<h2>
cv⁺ cv w⁺ w</h2>
