Why some chromosomes are recessive and the others are domainent?

Actually a chromosome consists of many genes/alleles and is neither recessive or dominant in and of itself.

Traits determined by recessive genes located on the x chromosomes are said to be?
Some traits are determined by recessive genes on the X chromosomes. Many times these are genetic disorders and are called recessive genes.
Is a gender a dominant or recessive gean?
Purebreds can be recessive or dominant, depending on their genotype. A genotype for spots on a griaffe could be AA (purebred dominant), Aa (heterozygous dominant), or AA (purebred recessive)? AA and Aa would both show the dominant phenotype, but only AA and AA are purebreds.
Is a allergie a recessive or a dominant?
It depends on the allergy, I assume. Some allergies may be recessive while others are dominant, while others still may be completely unrelated to genes.
Why are some parents traits expressed in their offspring and others are not?
Some traits are recessive and some are dominant. The recessive trait could be masked/hidden because of the dominant trait. Two copies of recessive alleles are needed to be shown in the phenotype.
What are the states that some alleles are dominant and others are recessive?
Mendel's law of inheritance.
Is pku sex linked recessive or sex dominant?
I think I read somewhere that there are some variants of it that are recessive and others that are dominant.
What is chromosomes theory of inheritances?
We have learned over a very long time that the chromosomes carry genes that determine who we are and what we look like. Some genes are dominate and some are recessive. A person with a widow's peak hair line shows a dominate gene for hair line. He may also carry a gene for "round" hair line but it is recessive and not seen.
Why are some characteristics inherited and others are caused by the environment?
Some characteristics are caused by the environment, some by inherited factors, while some are caused by both environment and inherited factors.Male mammals carry XY sex chromosomes - female mammals carry XX chromosomes. Inherited disorders are caused by faulty genes on these chromosomes.Different versions of a gene are called alleles, and these alleles can be dominant or recessive. Genetic diagrams can show the possible outcomes of a particular cross.
What does the principle of dominance state?
Basically, it states there are two forms of a gene called alleles, heterozygous in this case, and one allele masks the expression of the other allele. This is simplified, as it can get complex with co-dominance and partial dominance.
When two or more forms of the gene for a single trait exist some forms may be?
dominant and others may be recessive.
When some substances can pass across them but others cannot?
membrane
During sexual reproduction the new offspring gets half its traits from its mother and half from its father?
The new offspring will receive 23 chromosomes from the mother and 23 chromosomes from the father, for a total of 46 chromosomes. So in theory a new offspring will receive half the traits from their mother and half from their father. But some of their traits are dominant or recessive to if that father has all recessive genes and the mother has all dominant genes. There is a greater possibility that the new off spring would have more traits similar to their mother.
