A dominant gene (W) produces wire-haired texture in dogs; its recessive allele (w) produces smooth hair. A group of heterozygous

wire-haired individuals are crossed and their F1 progeny are then test-crossed. Determine the expected genotypic and phenotypic ratios among the test cross progeny:

Answer: Phenotypic ratio=2:2; Genotypic ratio= 2:2.

Explanation: Test cross is the breeding of an individual with Phenotypically recessive individuals.

Heterozygous wire-haired = Ww

Recessive trait= ww

Test crossing result of offspring= Ww Ww ww ww

Genotypic ratio (genetic composition) = 2:2

Phenotypic ratio= 2:2

2 offsprings are wire-haired and 2 Offspring are smooth-haired.

Answer:

I don’t necessarily suffer from the “CSI effect” because I know that what you see on TV isn’t what happens in reality. However, the one part that has caused me to fall into the “CSI effect” is that I thought the results were almost always, accurate and correct from a lab or test for example.

Explanation:  effects.....

1.It’s become more difficult to prosecute defendants

Today’s jurors want more hard evidence. They want the smoking gun and the DNA proof—the unmistakable proof that points to the perpetrator. But any legal professional will tell you this doesn’t always exist.

Some think this is why high-profile defendants like Casey Anthony and Robert Blake were acquitted in recent years. Circumstantial evidence and even eye-witness accounts don’t cut it in the shadow of the high-tech, flashy world of CSI and other shows. 21st century jurors are expecting sophisticated science to be included in every trial—even though it may not always reflect the reality of the case.

2.Jurors are becoming more knowledgeable

While CSI-viewers tend to have higher expectations for scientific evidence in trials, they also show patterns of superior legal knowledge compared to their non-CSI-watching counterparts. One survey indicated that CSI viewers were more likely to expect evidence relevant to a specific crime than non-CSI viewers. They also knew what type of evidence would be irrelevant to specific crimes.

However, more knowledgeable jurors isn’t always a good thing. Jurors may think they are more knowledgeable on forensic evidence than they truly are. They may be aware of forensic testing and its capabilities but not understand when it is appropriately used in a case.

3.It’s manipulating crime scenes

Criminals have access to the same television programming as the rest of us. Some believe the surplus in crime shows is changing their behavior as well. While these programs are not always entirely true, many of the proceedings are based upon facts.

Criminals are taking notes and becoming more skilled at covering their tracks. They know to wear gloves to avoid leaving fingerprints, and they know to use bleach to clean up incriminating evidence

4.Interest is increasing in the criminal justice field

If nothing else, crime shows are at least raising interest and awareness of the legal, medical and investigative professionals and what they do. Bringing the work of these often-overlooked criminal justice professionals to the public eye is introducing individuals to potential professional opportunities in the field.

How do sheet joints and exfoliation domes form in granite plutons?
fomenos
<span>Sheet fractures are accurate fractures defining slabs of rock that range from 0.5 to 10 meters thick. They normally form in sets parallel to the Earth's surface but may form in convex-upward or concave-upward sets. The most popular hypothesis of the formation of sheet fractures is that they are the result of expansion and tangential fracturing consequent on erosion offloading or pressure release.</span>

In Medicine, a diagnostic test can be used to identify a disease (sickness) or cause of symptoms.

This ultimately implies that, a diagnostic test avails medical professionals or experts the opportunity to identify illnesses and underlying causes of symptoms.

1. True: an oral examination limits the ability of a medical professional or expert (practitioner) to have knowledge of what is seen clinically.

3. The mechanism in which organisms best suited for their environment survive<br> and reproduce.
lys-0071 [83]

The mechanism in which organisms best suited for their environment survive

and reproduce <u>NATURAL SELECTION.</u>

<u></u>

Explanation:

When individuals in a population compete for resources or live in their environment, the individuals with the slightest advantage over the others have an increased chance of reaching maturity and  reproducing to passing down their genes to the next generations.

Natural selection works on the variations of the population to ‘select’ the best alleles of genes in the population that offer an advantage in ‘survival for the fittest’. This how natural selection fits a population to its environment. The greater the variation within a population, the higher its capacity to adapt to changes in the environment.
