the genetic code is carried by the DNA molecule in most organisms?
This is based on my assumption that brown is dominant over blue.
Since both parent have parents who are homo_zygous recessive, this tells us that both parents will be hetero_zygous.
When you cross two hetero_zygous parents, it can produce these genotypic and phenotypic ratios:
<u>Genotypic</u>
BB : Bb : bb
1 : 2 : 1
<u>Phenotypic</u>
brown : blue
3 : 1
Therefore there is a 75% chance that they will produce a brown-eyed offspring.
A large cloud of gas (hydrogen) and dust a nebula begins to collapse
The collapsing cloud begins to spin
The spinning collapsing cloud flattens into a rotating disk
Material in the disk begins to accumulate in the center
As the material coalesces in center, it becomes dense, compresses, and heats up.
More and more material coalesces to form a protostar.
The protostar continuse to accomulate material from the surronding disk and grow.
Eventually, the protostar becomes massive enough, dense enough and hot enough to cause the process of nuclear fusion to begin.
Nuclear Fussion isotops of hydrogen atoms (deuterium, tritium) combine to form helium atoms, energy, and subatomic particles.
Once nuclear fusion begins the protostar's “ignition” to nuclear fusion creates a solar wind that drives remaining gas and dust to the outer parts of the disk.
Then the young star stops accumulating material.
Solution:
In phylogenetic inference, an evolutionary novelty (or derived character) is referred to as Plesiomorphy
Relating to or denoting the process by which different kinds of living organisms are believed to have developed from earlier forms during the history of the earth.
Thus this is the required answer.
