In order for a child to inherit a recessive trait both parents must be carriers of the recessive gene?
No. A recessive gene can be inherited from one parent, a dominant from another, or two alike dominants. (No such thing as two alike recessive, the gene with the furthest back dominant gene. Say a blonde little girl has a blonde hybrid mother and a brown hybrid father. She ended up getting brown recessive. Since both of her parents were hybrid, she only had a recessive hair color gene from one parent.
What is the name for finger and toes?
The technical name for the fingernail is onyx
Pinky finger bone?
The pinky finger is the little finger. The word "pinky" comes from the Dutch word "pink" which means little finger.
Which metacarpal is proximal to the little finger?
The fifth metacarpal articulates proximally with the little finger. The fifth proximal phalanx meets the fifth metacarpal at the knuckle of the pinkie finger.
Brown eyes are dominant over blue eyes in humans The genetic makeup of blue-eyed children who have brown-eyed parents must be?
B (dominant) is for brown and b (recessive) is for blue. If both parents have brown eyes, for them to have a blue-eyed child their genotypes (the combination of b's) must both be Bb, because they both need to provide a little b (to have blue eyes you must be double recessive (bb)). This is worked out using a Punnett Square. (example: https://mcglynn-bioreview4.wikispaces.com/file/view/basicpunnetsquare.jpg)
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

What happens to A trait controlled by a dominant gene?
yes, if two Bb parents have kids, there is a 3:1 ratio that their children will show a dominant trait (BB Bb Bb bb). For multiple alleles (3 or more) it gets a little more complicated. Some traits, like height, have 1000's of genes affecting them. Consult your biology teacher for more information.Yes. Because to have a dominant trait you can have two dominant alleles or just one dominant and one recessive (because a dominant allele negates the effect of a recessive allele.) To get a recessive trait it takes two recessive alleles as oppose to a dominant trait where it takes only 1 to have a dominant trait. Therefore Dominant traits are more common.
What is the difference between recessive disorders and dominant disorders?
A sex linked dominant trait could be on the X chromosome of either parent and the phenotype of any individual carrier would be that of the dominant trait. A father with the dominant characteristic on his single X chromosome would produce daughters that are 100% carriers and would not pass the characteristic on to his sons. A mother who is a dominant X linked carrier would pass the dominant characteristic on to half hersons and half her daughters all of which would show the trait phenotypically. A sex linked recessive father would produce 100% carrier daughters. His sons would not get the recessive allele from him. A sex linked recessive carrier (heterozygous) mother would pass the trait on to 50% of her children and 50% of her sons would show the recessive trait genetics.
On which finger do you traditionally wear a signet ring?
Traditionally on the little finger of your non dominant hand ie if right handed on your left little finger
Do genes determine inherited traits or DNA?
Dominant and recessive alleles. Genes encode for proteins, which do all sorts of functions in your cells and body as a whole. If you have a certain allele of a gene, it will code for a specific type of protein. Different alleles are why everyone looks different.

Is a pinky a finger.?
The pinky finger is the little finger. The word "pinky" comes from the Dutch word "pink" which means little finger.
Is the little finger a finger?
It is a finger, just called a pinky
How are alleles different from genes?
A gene is a section of DNA that codes for a specific protein. An allele is the different forms of that gene. The commonly used examples are things such as eye colour (although this is an over simplification as the true nature of the genes governing eye colour are a little more complex): You have a GENE for eye colour. That GENE comes in (normally) two forms. These two forms are called ALLELES. One ALLELE is for blue eyes and one ALLELE is for brown eyes. ALLELES can be DOMINANT, RECESSIVE or CO-DOMINANT.
What is the genotype of the offspring that do not share the parents phenotype?
Genotype is the coded for traitPhenotype is the visible characteristicSo in the case where both parents had heterozygous dominant Brown eyes (Bb - big B for brown, dominant gene; little b for blue recessive gene); it is possible for the child to have blue eyes, by being homozygous recessive (bb).However this is an educated guess, as your question does not make sense.
What are the five fingers?
Thumb, index finger, middle finger, ring finger, little finger.
