Answer:
C
Explanation:
Assume that allele A is the dominant allele that produces the dominant phenotype (tall) in plants that have at least one allele A, and allele a is the recessive allele that produces the recessive phenotype (short) in plants that have two alleles a.
In the parental generation, a true-breeding tall plant has the AA genotype (phenotype: tall), and a true-breeding short plant has the aa genotype (phenotype: short).
We have the Gregor Mendel's cross as in the image attached here.
All of the F1 generation (offspring plants) have the Aa heterozygous genotype, and therefore, they are all tall.
The answer is c (the offspring plants have a genotype that was different from that of both parents).
Answer:
No, they are not. The concept of human races appears to be solidly grounded in present-day biology and our evolutionary history. But if you asked that conference of geneticists to give you a genetic definition of race, they wouldn’t be able to do it. Human races are not natural genetic groups; they are socially constructed categories. Genes certainly reflect geography, but unlike geography, human genetic differences don't fall along obvious natural boundaries that might define races.

Explanation:
I c have a true conclusion for my head but I think it is a good way for me to get
DNA replication goes in the 5' to 3' direction because DNA polymerase acts on the 3'-OH of the existing strand for adding free nucleotides. DNA replication can take place both the directions chemically. ... But these nucleotide triphosphates hydrolyze spontaneously under aqeuous conditions.
