Lubov Fominskaja [6]

Some skeletal traits that define modern homo sapiens are a small face, high rounded skull, small jaws, bony chin , vertical and high forehead, a narrow nasal aperture, narrow upper body and long legs is known as mental eminence.

<h3>What are skeletal traits?</h3>
  • The morphological diversity of the domestic dog serves as an example of how mammalian skeletal traits may evolve quickly and undergo significant modifications.
  • Here, we employ principal component analysis to identify systems of features characterizing skeletal traits in a population of Portuguese Water Dogs.
  • Through this research, phenotypic variation is divided into separate parts that can be utilized to analyze the genetic networks controlling intricate skeletal traits.
  • We demonstrate that unlinked quantitative trait loci associated with these major components separately support both inverse correlations between structures and correlations within skeletal traits (for example, within the skull or among the bones of the limbs) (e.g., skull vs. limb bones).

Question 1(Multiple Choice Worth 3 points)
shepuryov [24]

Answer:

1. It involves multiple trials

2. 2 red: 2 white

3. Process 1 describes cloning and process 2 describes artificial selection

4. Furry Feet

5. Large scale insulin could be produced in relatively lesser time

6. A lowercase letter

7. 0%

8. rr

9. 50%

10. The allele for white flowers is recessive in the pea plant

Explanation:

1. Repetition, this means to do over and over. This would involve multiple trials and this is done to test the reliability of the results and determine if the hypothesis holds true or not.

2. If you put your cross in a Punnett square it would look like this:

      R    r                            

r     Rr   rr                          

r     Rr   rr

Based on your problem: R = red; r = white

If the genotype would have a dominant allele (R), then the dominant trait will come out, if it has only recessive alleles (r) then the recessive trait will come out. So as you can see there are 2 red and 2 white. So the ratio would be 2:2 or 1:1.

3. Process 1 is considered as cloning, and to be more specific, reproductive cloning. The aim of this is to produce an offspring that has the same genetic make up as the original or parent organism. Process 2 is an example of artificial selection. This is also known as selective breeding where breeders choose certain traits to pass on to the off springs by selecting the organisms that have the traits desired.

4. Furry feet of polar bears provide them extra traction when they walk on snow. The fur also provides extra warmth. They also have foot pads on the soles of their feet that help them as well. Together, polar bear have something that works like snow boots.

5. Large-scale insulin could be produced in relatively lesser time because bacteria reproduce through asexual means. They produce copies of themselves that are genetically identical. An advantage of asexual reproduction is the process occurs in a much faster rate. With that said, insulin supply would increase, which will help many diabetic patients.

6. Recessive alleles in a genotype are represented by a lowercase letter. On the other hand, dominant alleles are represented by a capital letter. Squares and circles are used in pedigree charts to represent the whole genotype of an organism for a specific trait.

7. The answer would be 0% because cystic fibrosis is a RECESSIVE gene disorder. For it to be expressed or observable in an individual , t<u>hey should have two recessive alleles</u>. As you can see in the end result, none of the offsprings have 2 recessive alleles. The genotype Aa, has a recessive allele, but it will not be expressed because the dominant trait will mask it.

8. When we talk about homozygous, this means the alleles are the same. And when you say heterozygous, this means that the organism would have a dominant and recessive allele. the recessive llele is represented by a lowercase letter. So if the organism is homozygous recessive, the genotype would have two lowercase letters. (rr)

9. The scenario shows the genotype is pp. This means that the pea plant is homozygous recessive. As explained before, recessive traits are represented by lowercase letters. So this would mean that the white color is a recessive trait. The answer would then be the allele for white flowers is recessive in the pea plant.

10. Mitosis and meiosis are both forms of cell division. Mitosis produces daughter cells that are exactly the same as the parent cell, while Meiosis produces daughter cells that are different. They produce what we call haploid cells, which has only half the chromosomes of the parent cell. Gametes or sex cells are produced through meiosis, while body cells are produced through mitosis.

Zina [86]

Answer:

A terrarium with a plant and a snail

Explanation:

This is because snail uses oxygen for cellular respiration and releases carbondioxide as by product.

Where as plants uses carbondioxide exhaled for photosynthesis in the presence of light energy and chlorophyll with water to produce glucose and oxygen. Therefore cycle if oxygen and carbondioxide gases is continuous.
