In sweet pea plants, purple flower color is dominant over red flower color and long pollen grain shape is dominant over round po

llen grain shape. Two sweet pea plants that are heterozygous for both flower color and pollen grain shape are crossed with one another. A geneticist is surprised to observe that there are far fewer round, purple offspring and long, red offspring than were predicted by the 9:3:3:1 expected phenotypic ratio. Which of the following statements provides the most reasonable prediction to account for the deviation from the expected results?.

The most reasonable prediction to account for the deviation from the expected results is: in sweet pea plants, the gene for flower color and the gene for pollen grain shapes are genetically linked.

<h2>Who is the Father of Genetics?</h2>

Gregor Mendel is known as the Father of Genetics, as he established the principles governing the:

  • Laws of independent assortment,
  • Dominance, and
  • Segregation of genes.

However, certain exceptions to these principles exist, such as genetic linkage, which is an example of an exception to the law of independent assortment.

<h3>What is Genetic Linkage? </h3>

Genetic Linkage is the likelihood for genes or fragments of DNA adjacent together via chromosome to segregate simultaneously at meiosis and hence be inherited together.

The outcome of the parameters given can be interpreted as follows:

  • According to the Law of Independent Assortment, we need to know that two or more alleles of distinct genes assort separately or independently.

  • The genetic linkage takes place in the provided scenario, but it does not match the 9:3:3:1 ratio. This is because the genetic linkage does not obey the principles of independent assortment, hence, fewer purple offspring are produced.

  • As a result, mutations can cause Mendel laws to fail and have an effect on an organism's phenotypic features.

1. Kepler's three laws resulted from his careful analysis of ____ data, and were not derived from a mathematical model.
Sav [38]
<h2>1. Right answer: Observational </h2>

Kepler formulated the three laws of planetary motion <u>from observations made by</u> the Danish astronomer <u>Tycho Brahe of the orbit of Mars. </u>

These laws were enunciated to mathematically describe the movement of the planets in their orbits around the Sun. However, the scientific resources existing in his time did not allow him to prove these laws. It was Newton who did it after having developed the Differential and Integral Calculus and formulating the Laws of Universal Gravitation.

<h2>2.  Right answer: Aristotelian </h2>

Aristotle mistakenly thought that the Earth was the center of the universe, thus establishing a <u>geocentric cosmological model. </u>

According to this model, Aristotle proposed that the universe (the cosmos) was spherical and finite, with the Earth immobile at its center, composed of the four fundamental elements (made up of spherical layers): ground, water, air and fire; and the Sun along with the fixed planets in their respective concentric spheres revolving around the Earth. The outermost sphere being that of the stars and all these external elements being made of a fifth element which he called ether.

Which of the following foods do not require time and temperature control to limit the growth of pathogens and ensure safety.
OLEGan [10]

The temperature of a place often affect food. The option that is not of the Time/Temperature Control for Safety Foods is Processed garlic oil mixtures.

<h3 /><h3>Foods that require time and temperature control </h3>

There are different kinds of foods that require time and temperature control so that it can be safe. This food are known as TCS foods. They includes;

  • Milk and Dairy products
  • Eggs
  • Meat such as beef, pork, and lamb
  • Untreated garlic etc.

Garlic often stay  long does when process into oil in any temperature.  It can be safely store in oil for about 4 months in the freezer. Only garlic in oil mixture kept at room temperature for about two hours may not be useful.
