Answer:
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.
Explanation:
Before we answer your question, let's put your data into a Punnet square. The problem says that two heterozygous individuals will mate, so that means their phenotype is Pp.
P p
P PP Pp
p Pp pp
When you read a Punnet square to look for gentoypic ration, it refers to the Genotype, or let's just say the code and just count how many genotypes combinations you see out of the total, which in this case is 4.
PP = 1 out of 4 = 25%
Pp = 2 out of 4 = 50%
pp = 1 out of 4 = 50%
When we look at phenotype, we look for the trait that is expressed. If that is the case, you should remember that the dominant trait is ALWAYS expressed over the recessive. So if the genotype is Pp, the trait of the P is going to be expressed.
Polka-dot (P) = PP and Pp = 3 out of 4 = 75%
Solid (p) pp = 1 out of 4 = 25%
So looking at the result, the answer would then be B. 75% chance of a polka-dot tail and 25% chance of a solid tail (25%PP, 50%Pp and 25%pp).
Sensory organs are connected to the nerves in the body which is the feeling of pain or tickle they send signals to your brain to make sure the feeling is okay is pain is what is sent your brain tells you to stop
