Answer:
D. In autopolyploidy, one parental species contributes to the polyploidy; in allopolyploidy, two parental species contribute to the polyploidy.
Explanation:
Autopolyploidy is the polyploidy that arises when the organisms have more than two complete sets of the same genome. For example, if a diploid species is represented as "AA", its autopolyploid with four complete sets of the genome can be represented as "AAAA".
On the other hand, allopolyploidy occurs when the polyploid carries more than two complete sets of the genome from separate species. For example, if two diploid species are represented as "AA" and "BB", their allopolyploid with four complete sets of the genome can be represented as "AABB".
Answer:
True-breeding plants.
Explanation:
The self pollination in plants that produces progeny with similar characteristics or traits is called True-breeding plant. The parent and progeny both are identical genetically in true-breeding plants. The alleles shared between both offspring and parental plant is also same. The homozygous alleles are present in such organisms. The presence of homozygous alleles mean both alleles are same thus resulting in similar characters. Thus, plants that if left to self pollinate produce offspring identical to themselves are called True-breeding plants.
Answer:
To make sure that the experiment is accurate, the scientist must make carry out an appropriate observation, which would lead to the formation of good hypothesis. Good experimental method is an other criteria to look forward for the accurate experimental results. Methods are applied in collection of data and other things and in compiling results using statistical methods to carry out an accurate experiment.
Answer: A-T or G-C
Explanation:
The single-nucleotide polymorphism in human genomes is a substitution of a single nucleotide which occur in a specific position at the genome. The A-T nucleotide may appear dominant in the most population, while the remaining minor population may have the G-C nucleotide. The DNA molecule in the population at this site have A-T or G-C.

Either the cell wall or the cell membrane
