What are some examples of human traits that are not inherited by simple rules of inheritence in which one allele is dominant and the other is recessive?
While all traits are influenced in some way by genes, not all traits can be said to be controlled by genes. For example, a person's weight depends upon how much food that person eats, which is influenced by the environment; genetics will give you an appetite, but that does not necessarily mean that food will be available for you to eat. Similarly, we could say that an appreciation of Rock Music is not controlled by genetics, even though there is a genetic basis for the capacity to enjoy music. Still, if you never hear rock music you won't appreciate it, regardless of your genetics.

What is recessive traite?
relating to or denoting heritable characteristics controlled by genes that are expressed in offspring only when inherited from both parents, i.e., when not masked by a dominant characteristic inherited from one parent.
What are examples of recessive traits and dominant traits?
That's strictly a human view point. In fact there is no such difference, you just have two different proteins (one from each gene) which have behaviors relative to each other. How we (us, people) interpret the somatic result of the competition between them is labeled "dominant or recessive". For example - assume one form is totally non functional, then the somatic result would be classed as recessive.
All indiviuals who express a dominant trait?
All individuals who express a dominant trait possess at least one dominant allele for that specific trait. This means that even if they carry a recessive allele, the dominant trait will be expressed phenotypically. Dominant traits can mask the presence of recessive traits, leading to a variety of observable characteristics in a population. Examples include traits like brown eyes or curly hair, which can be passed on to offspring regardless of the recessive alleles they may carry.
Which MPS are inherited in an autosomal recessive manner?
Some examples of metabolic disorders inherited in an autosomal recessive manner include phenylketonuria (PKU), cystic fibrosis, and Tay-Sachs disease. In autosomal recessive inheritance, two copies of the abnormal gene are needed to manifest the disorder.
What gene shows up even when inherited only from one parent?
Lets say that your dad has brown hair, and your mom has red hair. The brown would be the dominant gene (B) and the red hair would be recessive (b). So you would most likely have brown hair since it is dominant. But if both parents had red hair (b) it would still be recessive. So the genes you inherited would be bb. You would then have red hair. If they both had brown (BB) then you would have brown. But if your parents did have brown and red hair, then you would have Bb. You would still then have brown hair since brown is the dominant color. But then if you have children, They would get one of each, so if you married someone with red hair, there is a possibility of your child of having red hair. I am not entirely sure if this answers the question, so I am sorry if it didn't. Hope it helped.
What is recessive traite?

What are some examples of dominant or recessive genes?
Examples of dominant genes include brown eyes and attached earlobes, where the dominant allele will be expressed over its recessive counterpart. Recessive genes include blue eyes and detached earlobes, which will only be expressed when an individual has two copies of the recessive allele.
What allele is covered up by the dominant allele?
An allele that's masked by a dominant gene is called a "Recessive"recessiverecessive traitThe recessive allele. Often depicted as the "small r" in examples: Rr, R=dominant, r= recessive.
What is a dominate trait?
Dominant trait is a genetics term. A dominant trait is one which will be expressed if one of the parents has the gene for that trait. A recessive trait is one that will be expressed only if both parents carry the trait.
Trait of an organism that can be masked by the dominant by the dominant form of a trait?
A recessive trait is a characteristic of an organism that can be masked by the dominant form of a trait. It is only expressed when an individual inherits two copies of the recessive allele. Examples include blue eye color being masked by brown eye color.

What genes are recessive traits?
These traits are called dominant traits. They will overcome the recessive gene and the dominant trait will be expressed. A recessive gene needs two alleles present in its genotype to be expressed.
What is an example of dominant inheritance?
Dominant Inheritance is when one parent has a dominant gene and the other has a recessive gene. The dominant gene overpowers the recessive gene, and only the dominant gene is phenotypically expressed.Source: http://www.accessexcellence.org/RC/VL/GG/recessive.phpSome examples are variegate porphyria, Huntington's disease and myotonic dystrophy.source: http://genome.wellcome.ac.uk/doc_WTD020849.html
What is recensive characters?
Recessive characters are traits that are expressed in an organism only when two copies of the recessive allele are present, meaning that the organism must inherit one recessive allele from each parent. If a dominant allele is present, it will mask the expression of the recessive allele. This concept is central to Mendelian genetics, where traits are determined by pairs of alleles, one from each parent. Examples include traits like blue eye color or certain inherited disorders.
All indiviuals who express a dominant trait?

Can you provide some examples of Hardy-Weinberg equilibrium practice problems along with their answers?
Here are a couple of examples of Hardy-Weinberg equilibrium practice problems: In a population of 500 individuals, 25 exhibit the recessive trait for a certain gene. What is the frequency of the dominant allele in the population? Answer: Let p be the frequency of the dominant allele and q be the frequency of the recessive allele. Since q2 0.25, q 0.5. Therefore, p 1 - q 1 - 0.5 0.5. The frequency of the dominant allele is 0.5. In a population of 1000 individuals, 64 exhibit the dominant trait for a certain gene. What is the frequency of the recessive allele in the population? Answer: Let p be the frequency of the dominant allele and q be the frequency of the recessive allele. Since p2 0.64, p 0.64 0.8. Therefore, q 1 - p 1 - 0.8 0.2. The frequency of the recessive allele is 0.2.
