State Mendel's principle of dominance?
Only the dominant trait can be seen in an organism that is hybrid for a pair of contrasting traits
What is the genetic composition determining a trait?
Genotype is the genetic makeup of a trait.
What does human height mean when it comes to polygenic trait?
Trait is controlled by more than one pair of genes.
What makes something a sex-linked trait instead of just a regular trait?
A sex linked trait can only be found on the x chromosome such as hemophilia, color blindness, and muscular dystrophy. These are traits that can only be inherited through chromosomes instead of regular traits coming through genes.
Would a disease caused by exposure to chemicals be considered a genetic trait?
A genetic trait is passed on through the genes. Which means that disease from exposure to chemicals is not inherited.
What alleles are mask in complete dominance?
A recessive trait is a trait with two contrasting alleles. In some cases contrasting alleles for a trait are codominan, that is, both are expressed.
What is the definition of a contrasting trait?
l.
What is it called when three or more contrasting genes control a trait?
Polygenic
Explain Mendel's law of independent?
Mendel's Law - The first law of Mendel states that "In a cross of parents that are pure for contrasting traits, only one form of the trait will appear in the next generation. Offspring that are hybrid for a trait will have only the dominant trait in the phenotype."
What is law of dominance and how do traits manifest if it is from a parent with this type of trait?
Mendel's law of dominance states that when two pure breeding organisms of contrasting traits (such as purple flower or white flower) are crossed, only one trait of the pair appears in the F1 generation. This is known as the dominant trait (purple), and the other unexpressed trait (white) is recessive.
The principle or law of heridity which states that only the dominant trait can be seen in an organism that contains in genes a pair of contrasting traits is called?
Mendles law of dominance
What is a contrasting form of a hereditary characteristic called?
I had this question on a test as a multiple choice so I know the answer is either genotype, heredity, allele or gene if that helps.
What does contrasting mean in music terms?
Contrasting in music is the same as contrasting in general: something is different. There might be a fast section and a contrasting slow section, a high section and contrasting low section, a major section and contrasting minor section, and so on.
What does Gregor Mendel law of dominance state?
Mendel's law of dominance states that if you have a pair of genes then the one that shows up in the offspring is most likely the dominant gene because the dominant is passed along more often than the recessive.
What are the two contrasting regions?
There are more than two contrasting region. The top two contrasting region are the East and the West.
Two plants are crossed resulting in offspring with 3 to 1 ratio for a particular trait?
that the parents were true-breeding for contrasting traits. NOT TRUE. If so, all the offspring would be identical genotypes. Think of a classic cross that gives you a 3:1 ratio and write it out. It would suggest that the parents were both heterozygous for a single trait.
Why is it essential that the primary stain and the counterstain be of contrasting colors?
It is essential that primary stain and the counterstain be of contrasting colors so that the target of the primary stain can easily be differentiated on a contrasting background.
