...The origin of life on Earth is a set of paradoxes. In order for life to have gotten started, there must have been a genetic molecule.. something like DNA or RNA—capable of passing along blueprints for making proteins, the workhorse molecules of life.

<em>Deer are herbivores</em>
Explanation:
<em>Deer are herbivores, that is, they eat plants. The diet of a wild deer includes such things as grass, bark, twigs, berries, young shoots and other vegetation. Deer eat about two pounds of dry food each day for every 100 pounds of body weight.</em>
Answer:
A) Allele symbol: C/c
B) Wild-type: there are two options: Cc is 3 cotyledons are recessive, and cc if 3 cotyledons are dominant.
Explanation:
According to this example, the mutant plant with three cotyledons was crossed with a wild-type one. There were 298 wild-type plants and 302 mutants (three cotyledons). This means a 1:1 ratio.
So, to obtain a 1:1 ratio, one parent should be heterozygous and the other one should be homozygous recessive. As parents are phenotypically different, this trait can be recessive or dominant, but in both cases, one parent has to be heterozygous. If it is assumed that the trait is recessive, the mutant plant would be cc, and wild-type would be Cc. Another option is that the trait will be dominant, in this case, the mutant plant would be Cc and wild-type would be cc.
To know is the trait is dominant or recessive is necessary to make a new cross between the mutant plants of this F1.
In the attached Punnett Square is showed the two possible crosses.
