You are doing lab work with a new species of beetle. You have isolated lines that breed true for either blue shells and long ant

enna, or green shells and short antenna. Crossing these lines yields F1 progeny with blue shells and long antenna. Crossing F1 progeny with beetles that have green shells and short antenna yield the following progeny: blue shell, long antenna 82 green shell, short antenna 78 blue shell, short antenna 37 green shell, long antenna 43 total 240 a. Which shell color and antenna length alleles are dominant?

Answer:

Due to the fact that when crossing the isolated lines, the F1 progeny expression resulted in all alleles having blue shells and long antennas,  the dominant <em>shell/color & length/antenna</em> combination is:

<em>"</em><em>Blue Shell & Long Antenna</em><em>"</em>

Crossing over occurs between homologous chromosomes, and is closely involved in genetic variation. <em>The stage that most contributes to </em><em>diversity</em><em> is stage C, </em>where you can see chromosomes after crossing-over.

----------------------------  

There are different mechanisms involved in producing genetic variation among descendants. These are,

  • Crossing-over between homologous chromosomes (prophase 1),
  • Random lining of homologous chromosomes (metaphase 1),
  • Random fertilization  

The Crossing-over events occur between two homologous chromosomes in the equatorial plane and make the daughter cells genetically different from the original one.

The Chiasma is the position where two homologous chromatids interchange genetic information, giving a place for new genetic material or information to be provided to descendants.

After crossing over, homologous chromosomes get separated again.  

In the attached imaged there are four different stages of meiosis.

Stage C is the one that contributes the most to diversity.

We can see that crossing over has already occurred between homologous chromosomes, and they have already interchanged segments.

<em>In the image you will see the difference between </em><em>chromosomes</em><em> that has gone through the</em><em> crossing over </em><em>mechanism, and </em><em>chromosomes</em><em> that has not. The difference in color represents segments interchange and variation.</em>

What were Louis Pasteur's experiments related to spontaneous generation?
Tamiku [17]
Spontaneous generation was a (refuted) theory that some forms of life can arise from inorganic matter. 

Louis Pasteur refuted it in a series of experiments, in which he boiled different matter (grape juice, broth) which would kill all the bacteria and let it stay for a long time to see if it would develop life (he also had a control condition in which he let the boiled liquid interact with the outside words, and those would develop bacterial life).
