There is no prescribed length of time it takes to photographically document a crime scene. The amount of time spent depends on the size and complication in the crime scene, how much there is to document and environmental factors like weather or danger to the investigative team. It can consist of thousands of photographs and hours of work.
Crime scene photography should not just focus on the obvious. The purpose of crime scene photography is to document what is there and where it is in relationship to the scene, whether it is obviously connected to the crime or not. For example, a photographer in Florida shot the inside of every cabinet and the refrigerator at a homicide scene in a home, just as a matter of procedure. It was later discovered that the victim had a receipt for a six-pack of beer, matching the beer shown in the photograph of the refrigerator. Relatives noted that the victim did not drink beer. Further investigation led the team to the convenience store where the beer was purchased and the surveillance tape showed the victim with an unknown person purchasing the beer. It turns out that the victim had picked up a hitchhiker, purchased beer for that person and come back to the house. The photograph of the refrigerator contents had created the link enabling the investigators to find the suspect.
No daughter (0%) will have the color blindness.
<h3>How to make a cross to find the genotype of the offspring?</h3>
Genotype of woman with normal vision = XX
Genotype of man with color blindness = XYᵇ
Gametes formed from woman = X and X
Gametes formed from man = Xᵇ and Y
Crossing both the parents (Using Punnett square):
X X
Xᵇ XXᵇ XXᵇ
Y XY XY
Out of the four progeny 2 are boys and 2 are girls.
Sons do not carry the gene for color blindness.
Daughters are the carrier for the color blindness.
No daughter will have the color blindness. They are the carriers for the disorder.

Answer:
The correct option is A.
Explanation:
There are two basic types of reproduction, they are asexual and sexual reproduction. Asexual reproduction involves the division of a mature organism into two different organisms through binary fission or other forms of asexual reproduction. In this case the offspring is similar both physically and genetically to the parent organism. There is no genetic diversity in this case and the same disease can easily wipe out the entire population of the organism.
Sexual reproduction on the other hand requires two different organisms. During the reproductive process the genetic materials from the two organisms get mixed up thoroughly, so they end up giving birth to offspring that are quite different from them genetically.
The diversity in genetics makes it possible for the offspring to cope with changing environmental conditions. Because, the offspring are diverse in constitution, some offspring will always be able to survive harsh environmental conditions due to their genetic make up.
Yes ,is the anger of these questions.
B. a form of gene is the correct answer
