Is kleinfelters syndrome recessive?
Kleinfelters is a chromosomal "trisomy" of the sex chromosomes. It is not inherited in a recessive or dominant manner.
What can be dominant or recessive?
Alleles can be dominant or recessive
Is Trisomy 8 dominant or recessive?
neither, it is not heridetary, it happens when there is a problem between sperm and egg and some of the cells don't split properly. it's a chance occurence
What is dominant recessive?
There is dominant and there is recessive. There is no dominant recessive. A dominant gene will always be expressed when present, such as in the homozygous dominant genotype (RR), or heterozygous genotype (Rr). A recessive allele is only expressed when the genotype is homozygous recessive (rr).
Can someone give you a List of dominant or recessive personality traits?
1. Shape of face (probably polygenic) Oval dominant, square recessive 2. Cleft in chin No cleft dominant, cleft recessive 3. Hair curl (probably polygenic) Assume incomplete dominance Curly: homozygous Wavy: heterozygous Straight: homozygous 4. Hairline Widow peak dominant, straight hairline recessive 5. Eyebrow size Broad dominant, slender recessive 6. Eyebrow shape Separated dominant, joined recessive 7. Eyelash length Long dominant, short recessive 8. Dimples Dimples dominant, no dimples recessive 9. Earlobes Free lobe dominant, attached recessive 10. Eye shape Almond dominant, round recessive 11. Freckles Freckles dominant, no freckles recessive 12. Tongue rolling Roller dominant, nonroller recessive 13. Tongue folding Inability dominant, ability recessive 14. Finger mid-digital hair Hair dominant, no hair recessive 15. Hitch-hiker's thumb Straight thumb dominant, hitch-hiker thumb recessive 16. Bent little finger Bent dominant, straight recessive 17. Interlaced fingers Left thumb over right dominant, right over left recessive 18. Hair on back of hand Hair dominant, no hair recessive 19. Tendons of Palmar Muscle Two tendons dominant, three tendons recessive
Is melanoma dominant or recessive?
is malignant melanoma dominant or recessive
What is the difference dominant and recessive trait?
Dominant traits are the traits that mask the recessive traits. The dominant traits are stronger than recessive!
Is Edward's syndrome caused by a recessive gene?
Edward's syndrome is not technically recessive or dominant, because it is not caused by a single gene. Rather it happens due to a trisomy of chromosome 18 (or just of a part of said chromosome). Parent's may be healthy and still have offspring with the syndrome not because its recessive, but because the trisomy arises during meiosis of the gametes. Whatever happens to the gametes affects only the offspring not the carrier parent.
Is a widows peak dominant or recessive?
Dominant definitely not dominant. It is recessive objectively and subjectively and unequivocally.
Is trisomy dominant o recessive?
Its not a question of dominant or recessive, because Trisomy doesn't refer to a gene. Trisomy is a chromosome disjunction, meaning that its a failure at the level of chromosomes. In most cases it is caused by a triple of the 21st chromosome (normal people just have it two times). So in Meiosis this triplett wouldl be theoretically split: one in the first daughter cell and two in the second cell. (We ignore the low chance of another disjunction, were all three copies of the 21st chromosome get in one daughter cell and none in the other). Mathematically the chance of passing trisomy on is roughly about 50%. But most people with that trait aren't fertile.
Is a situation in which a dominant allele completely masks a recessive allele for a gene.?
If you have 2 dominant alleles, the gene will be dominant, if you have 2 recessive alleles, the gene will be recessive. But if you have 1 recessive and 1 dominant, the Dominant allele will mask the recessive one.
How do you xxplain dominant and recessive?
Recessive
