Why are many harmful alleles recessive?
The reason many harmful alleles are recessive is because the harmful alleles that were dominant stopped the carrier from reproducing so the allele was not carried on. A dominant trait is expressed if present and would harm the carrier. A recessive trait however can remain in the genotype of an individual and not the phenotype so they will not be harmed by the trait but can pass it on to offspring. In short: dominant harmful alleles stopped the carriers from producing so the allele was not spread.
What is an organism that is heterozygous for a harmful trait?
Assuming the deleterious trait is recessive, the individual would be called a carrier.
Are dominant alleles always more common?
A honozygous gene will be expressed, but not necessarily because it is dominant; it would be expressed because there is no alternative. If I ask you to pick one of two cards, and they are both the jack of diamonds, what card will you pick? To know if a gene is dominant you have to find out if it actually will be expressed even when there is a different gene for that trait, with which it is paired.
Genetic disorders are caused by?
Genetic Disorders are caused By a change in a person's DNA. Recessive alleles is the most human genetic disorder.
What does a cell wall do for the palnt cell?
Helps maintain plant's shape. Gives protection against the entrance of harmful subtances and microbes.
Why would harmful genes still get passed from generation if they were harmful to the individual?
Harmful recessive or dominant traits will remain in the population as long as the individuals are unaffected or only moderately affected allowing them to reproduce, or if recessive, they are at a low enough frequency in the population that they are rarely expressed and therefore not selected against at a significant rate.

How can a lethal allele continue to be present in a gene pool even when they are selected against?
A harmful recessive allele remains in the population because both homozygous dominant and heterozygous genotypes produce the dominant, healthy phenotype. So the heterozygous genotype keeps the harmful recessive allele in the population.
Is it true that people who are heterozygous recessive allele but who have a normal phenotype eill not pass the harmful recessive allele to their kids?
It depends on the genotype of the childs other parent. If your partner is heterozygous as well then there is a 25% chance your child will be homozygous recessive. If they are homozygous dominant then none of your children will have the phenotype of the recessive trait. They will just possibly be carriers of the recessive allele.
why are structures not removed by natural selection?
Vestigial structures do not harm the organism. Nature selects against only harmful traits.

Is the white tigers fur mutation dominant or benificial?
Well, the white tigers fur mutation isn't dominant nor beneficial (depends). The allele for white fur in tigers is recessive and even then not many tigers are heterozygous (One dominant allele and one recessive allele for those who do not know) Now it can be beneficial depending where the tigers live, there used to be Siberian Tigers who lived in the snow so it would be beneficial there but white fur will decrease stealth ability in the jungles, therefore alleles can be beneficial or harmful depending on the allele and where the organism lives.
Can you sleep with your siblings or is that against religion?
If you mean "sleep with" in the sense of sexual intercourse, that is against almost any religion, and it is very much frowned upon by most societies.The reason for this is that if you make children with close relatives, you have a high chance of those children being abnormal, due to a possible accumulation of recessive harmful genes.If you mean "sleep with" in the sense of sexual intercourse, that is against almost any religion, and it is very much frowned upon by most societies.The reason for this is that if you make children with close relatives, you have a high chance of those children being abnormal, due to a possible accumulation of recessive harmful genes.If you mean "sleep with" in the sense of sexual intercourse, that is against almost any religion, and it is very much frowned upon by most societies.The reason for this is that if you make children with close relatives, you have a high chance of those children being abnormal, due to a possible accumulation of recessive harmful genes.If you mean "sleep with" in the sense of sexual intercourse, that is against almost any religion, and it is very much frowned upon by most societies.The reason for this is that if you make children with close relatives, you have a high chance of those children being abnormal, due to a possible accumulation of recessive harmful genes.
What is group discrimination?
harmful intentional by a small number of dominant and group members with out direct support of norms and most other dominant group members. and example would be hazing, which is illegal but it can still happen with harmful intentions that are supported by a small number of a dominant group like a sorority.
