The correct answer is B. 1 red; 2 pink; 1 white
Explanation:
In genetics, the combination of alleles (genotype) determines the phenotype or physical features; for example, in this case, the color of the flowers in the snapdragon plants can be determined by the combination of dominant alleles (R) and recessive (r) alleles. Additionally, in the case presented, a dominant allele combined with a recessive allele (Rr) leads to pink snapdragon plants, while two dominant alleles (RR) lead to red snapdragon plants, and two recessive alleles (rr) lead to white snapdragon plants.
According to this, the generation F2 shown in the chart produced 1 red plant because there is only one plant with RR genotype; 2 pink plants because there are two plants with Rr genotype; and finally one white plant because the last plant has an rr genotype.
Answer:
The main difference is the presence of a nucleus.
Explanation:
One of the biggest differences is the presence of a nucleus with an envelope. This is very important because in eukaryotes it is present, but in prokaryotes, the genetic material is in the cytosol, although it's not exactly dispersed, it's slightly grouped. Also, the DNA in prokaryotes is organized in circular chromosomes while in eukaryotes it's organized in linear chromosomes arranged in an X shape. There are many more differences, but these two are the more important ones.
