Rom4ik [11]

Answer:

genes for flower color and edge shape are linked. They do not assort independently.

Explanation:

<u>Available data:</u>

  • test cross between a purple-flowered pea plant having serrated leaves and a white-flowered pea plant having smooth edges.
  • serrated leaves → dominant trait
  • smooth edges → recessive trait
  • purple color → dominant trait
  • white color → recessive trait
  • F1: 4 purple-serrated:1 purple-smooth:1 white-serrated:4 white-smooth.

There are two genes involved in the cross. The expected ratios are 1:1:1:1 because we assume genes assort independently. However, we see a different phenotypic distribution. When phenotypic ratios differ from the expected ones, it means that genes are linked.

To know if two genes are linked in the same chromosome, we must observe the progeny distribution. If individuals, whose genes assort independently, are test crossed, they produce a progeny with equal phenotypic frequencies 1:1:1:1. But if instead of this distribution, we observe a different one, that is that phenotypes appear in different proportions, we can assume that genes are linked in the double heterozygote parent

Overall, how has science impacted human health?
mixas84 [53]

Answer:

The correct answer is: <em>C. Increased average lifespan to 78 in the US.</em>

Explanation:

Science has impacted human health by increasing the average lifespan to 78 in the US. Over the last couple of decades, the life expectancy of Americans has increased significantly than what it was 200 years ago. This can be attributed to:

1. Vaccinations- Since the invention of vaccinations, diseases such as tuberculosis, cholera and polio which were major causes of death 200 years ago have virtually been eradicated in the US.

2. Abundant and safer foods available- Commercial and large scale farming has made a wide variety of nutritious foods easier to obtain.

3. Improved sanitation- Safer drinking water, sewage treatment and stricter food inspection has significantly reduced the rate of illnesses due to poor hygiene and sanitation.  

In these ways, science has impacted human health by increasing the average lifespan to 78 in the US.
