The principle of dominance states that??..... a biology question?

Question

well what does it state. 1st person to anwser right will get 10 points

Answer 1

Dominance means that u have two allele which are homozygous example AA. And the chances of passing on the alleles is very high.

In Evolution, it is describing that the survival of the fittest. The top of the pyramid of that survival of the fittest is most dominant because it is the fittest to survive and reproduce.

Answer 2

1 C We can eliminate all other choices because we know for a fact they're not true. For any trait, there are a recessive, represented by a lower case, and a dominant, represented by capitals. #2 B I'm pretty sure this is the answer, but not completely. It's very reasonable because in order for a trait to appear, it has to be dominant, or homozygous recessive. The other choices don't suggest a homozygous recessive and are irreverent. Hope this helps, good luck!

Answer 3

One of Gregor Mendel's great discoveries was the Principle of Dominance. He noted that when he hybridized two parents with different versions of a particular trait, one of those versions apparently disappeared in the hybrid (heterozygous) offspring. If he then mated those offspring to each other, the vanished trait reappeared in the third generation, apparently completely unchanged despite being invisible in generation 2. He named the version of the trait which was visible in the hybrids the dominant and the one that was invisible in the hybrids the recessive.

We now know that Mendel discovered complete dominance, which is only one of several different kinds of dominance relationships. Dominance relationships result from the interactions of the gene products of different alleles of the same gene (not from interactions between different genes). Note that dominance is virtually always defined with respect to the phenotypic of the heterozygote.

Answer 4

The principle of dominance states that some alleles are dominant and others are recessive.

Answer 5

Dominance is when a trait masks another. The allele could be either AA or Aa. This really only applies to a single gene trait.

My science teacher in 7th grade tried to teach dominance to us using the example of right-handed dominance over left-handed. She said that two left-handed parents could never have a right-handed child. This is not the case as it is controlled by more than one gene, two left-handed parents have only a 27% chance of having a left-handed child. My sister and I are living proof of that since both of our parents are left-handed, and we are both right-handed.

Answer 6

Mendel's principal of dominance simply says that in a heterozygous individual (or hybrid) the dominant allele will show up in the phenotype and the recessive allele will not show.

That's it.
