What are some very excellent examples of recessive and dominant genes,eyes,ears,hair,nose,handedness,and more?

Question

give me details,i wanyt as many as you can tell me about all the recessive genes you can tell me about,and all the dominant,EVERYTHING!,thank you :)

Answer 1

Autosomal recessive is a mode of inheritance of genetic trait located on the autosome, the 22 non sex-determining chromosomes. In opposition to autosomal dominant trait, a recessive trait only becomes phenotypically apparent when 2 copies of a gene two alleles are present. In other words, the subject is homozygous for the trait. Technically, the term recessive gene is impresive because it is not the gene that is recessive, but the phentype or trait or alleles. Gene therapy is a promising new field of medical research. Researchers try to supply copies of healthy genes to cells with variant or missing genes., so the ""good genes will take over. Viruses are often used to carry the healthy genes in to the targetted cells; because many viruses can insert their own DNA into targetted cells.

Here is a list of dominant traits and recessive traits.

DOMINANT TRAITS

eye coloring: brown eyes

Vision: farsightedness

Hair: dark hair,curly hair, non-
red hair, full head of hair, widow's peak

Facial features: dimples, unattached ear
lobes, broad lips,freckles
appendages : extra digits,fused digits short digits, finger lack joints, limb dwarfism,
clubbed thumb,double jointedness

Other: immunity to poison ivy,
normal, no PKU


RECESSIVE TRAITS

eyecoloring- grey, green, hazel, blue eyes

Vision- nearsightedness, color blindness

Hair- blond, light red hair

Facial features- no dimples, thin lips

Other- susceptibility to PKU

Recessive Disorders; Cystic fibrosis, lung disease; Tay-Sachs- nervous system problems, chronic granulotomasus, Bloom's Syndrome, Bleeding disorde, hemophylia, Sickle cell anemia- a blood disease.

Dominant Disorders Achondroplasia, a form of dwarfism, Marfan's syndrome- a connective tissue disorder, Huntington's Disease- a degenerative disease of the nervous system.

This is a vey detailed list. Hope it helps. It required extensive research.

Autism is not entirely genetic. If it was, there would be no cases of identical twins where one is autistic & one is not. But genetics is a major factor in autism. I usually tell people "a person does not inherit autism as much as they inherit the vunerability to develop autism." And many genes are involved. As many as 50 genes! THey could be dominant, but autism will only result if all the required genes are present. But lets say only 6 genes are required. Lets say Mommy has 3 of the genes & Daddy has 3 more genes. Neither parent has autism because they don;t have all the genes required. Only if a child inherits all 6 genes, will he be autistic. Believe it or not, that is the simple version. There seem to be different genes reqired for a boy to have autism than for a girl. Dr. Geraldine Dawson is my favorite researcher on the subject.

Answer 5

Red hair is a recessive gene, not a dominant, which is why it skips generations.

Answer 6

Brown is the dominant Eye colour. Blue, green and violet are recessive.

Answer 9

I don't know if I can give you Everything, since I don't know everything but I know a few. Although these are dominant traits, it doesn NOT mean that they are neccesarily common. I find that interesting, but its true. Thats why you can have three generation of no red hair in a family and all of the sudden out pops a red head. Its a dominant gene that does not go away, even over time.

Attached ear lobes, red hair, widows peak, darker hair color, 6th finger
