Answer:
The involvement of more than two genes.
Explanation:
The polygenic characteristics have many phenotypes because more than two genes governs the phenotype of individual organism. The single gene contains a pair of alleles that codes for two phenotype and two genes will code for 4 phenotype. Thus, more than two genes for example, three genes will have six phenotypes.
The skin color and height are polygenic characterstics in humans.

3. How far apart are Y and B?
Answer:
Y and B are 16 map units apart
Explanation:
Hope this kina help :)
The answer should be B, prokaryotic cells use binary fission as a means of "reproduction"
Answer:
Co-dominance because he expresses both of the alleles simultaneously
Explanation:
The ABO blood group system is used by humans. This blood group type is controlled by multiple alleles. Alleles A and B are both dominant over allele O but are co-dominant. Co-dominance is a type of inheritance pattern in which two alleles of a gene both express themselves i.e. neither is recessive.
This is the case of this family whose parents have a genotype of AO (blood type A) and BO (blood type B) respectively. The children have blood types A, B, and AB. However, the child with genotype AB possesses both the A and B allele, which are both expressed in his blood group (phenotype), hence, it can be said that the child is exhibiting CO-DOMINANCE for the blood group trait.
Answer:
1- substitution.
2- neutral.
Explanation:
The change in the genetic sequence of the organisms known as mutation. Mutations might be sudden and heritable in nature. spontaneous mutation and induced mutation are types of mutation.
A change that causes a change in single base pair of a gene sequence is called substitution mutation. The original leucine sequence is GTT and the mutated sequence is GTG. Thus T has been substituted by G.
Mutation can be beneficial, detrimental or neutral. The neutral mutation is that does not affect the physical change. Both GTT and GTG code for the same amino acid so it would be neutral.
