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.

Why are solid particles required for cloud formation?
viktelen [127]

In a classic experiment using pea shape, Mendel conducted two separate genetic crosses. In the first cross the parent plants wer
Kamila [148]

The question is incomplete. The rest of the question is :

From these experiments, Mendel developed four hypotheses. They include all but ___________. A. One heritable factor may be dominant and mask the other factor. B. Any organism that "shows" a heritable factor must be homozygous. Eliminate C. An organism has two "heritable factors", now called genes, one from each parent. D. sperm or egg carries only one heritable factor for each trait in the offspring.

Answer:

<em>The hypothesis which is excluded is B 'Any organism that "shows" a heritable factor must be homozygous.'</em>

Explanation:

The hypothesis is wrong because even heterozygous traits are heritable.

The hypothesis mentioned in option B cannot be considered correct because Mendel's studies showed that all traits can be inherited from the parents. All factors whether dominant or recessive, homozygous or heterozygous are heritable characteristics. Mendel's study also confirmed that genes might carry homozygous or heterozygous alleles and these alleles independently assort into gametes and are heritable.

All other hypotheses are correct and their authenticity was validated after Mendel performed his experiments.
