The law that best explains why an organism with the genotype Tt will exhibit only the dominant phenotype is the Law of Dominance. This principle, established by Gregor Mendel, states that in a heterozygous genotype, the dominant allele (T) masks the expression of the recessive allele (t). Consequently, the presence of one dominant allele is sufficient to produce the dominant phenotype, resulting in the organism displaying that trait.

What statement best describes a dominant allele?
A dominant allele is a variant of a gene that expresses its trait even when only one copy is present in the organism's genotype. This means that if an individual has at least one dominant allele for a particular trait, that trait will be visibly expressed, overshadowing any recessive alleles that may also be present. Dominant alleles are typically represented by uppercase letters in genetic notation.
When a trait has more than two different forms it would be best described by what terms. A. Recessive B. Dominant C. Incomplete dominance D. Phenotypic E. Multiple alleles?
E. Multiple alleles. Multiple alleles refers to a gene that has more than two alleles which can result in a larger number of possible trait variations. This is different from traits that are controlled by dominant and recessive alleles, or exhibit incomplete dominance.

To perform a testcross scientists cross an organism with an unknown genotype with a organism.?
If an individual is of the dominant phenotype, its genotype can be either AA or Aa (letter A picked for demonstration's sake). To do a good test cross, we have to be able to unambiguously tell which one of the genotypes the individual is. The best test cross would be conducted with a homozygous recessive (aa) individual. This way, if the cross generates 100% dominant phenotype, then the original individual was homozygous dominant. If the cross generates 50% dominant and 50% recessive phenotype, then the original individual was heterozygous.
Which statement best explains the observation that clones produced from the same organism may not be identical?
gene expression can be influed by the environment
The phenotypic ratio for a testcross with a homozygous individual and a heterozygous individual is?
If you're given a general situation, it's best to make one up of your own and see the results. Say the dominant trait is B and the recessive trait is b. Therefore, a heterozygote would be Bb. If you cross a Bb with a Bb, you will get BB, Bb, Bb, and bb. Any offspring with just one dominant allele will have the dominant trait. So three of the four (75%) are phenotypically dominant and one of the four (25%) is phenotypically recessive.
Which of these best explains how mutation can be beneficial to an organism?
Mutation can introduce new genetic variations that can lead to advantageous traits, such as increased resistance to diseases or better adaptation to changing environments. This can give the organism a survival advantage and increase its chances of reproductive success, ultimately aiding in evolutionary change and diversification.

Which statement best explains why a living organism in a wet mount moves into and out of focus within the field of view of a microscope?
The movement of a living organism in a wet mount is due to its natural mobility and activity. The organism may move up and down, into and out of focus, as it changes its position within the water droplet on the slide. This shifting focus is a common occurrence when observing live specimens under a microscope.
