In genetics, the bobtail trait is typically recessive because it is masked by the dominant long tail trait. This means that an individual needs to inherit two copies of the bobtail allele to express the bobtail trait, whereas only one copy of the long tail allele is needed to display the long tail trait.

Are tight eyelids a dominate or recessive trait?
Trait inheritance is more complex than a simple dominance or recessive model. The expression of eyelid tightness can be influenced by multiple genes and environmental factors, making it difficult to categorize as solely dominant or recessive.
Is turner syndrome a dominant or recessive?
yes it is a recessive trait
Are dominant or recessive alleles easier to remove by selection?
Natural selection favors whatever allele provides a selective advantage, so in theory it can operate on either. However, if a recessive allele provides an advantage it will soon shift and become the dominant allele, so it could be argued that natural selection favors dominant alleles. This is only partly true. A dominant gene always has some effect on the characteristics of the organism, even if the owner only has one of them. A recessive gene only affects the characteristics if there is no equivalent dominant gene to mask the effect. If both parents possess the recessive gene there is a chance the offspring will have two of them and this will show in their characteristics. When this happens, natural selection operates on the recessive gene. Much of the time, a recessive gene is present but natural selection does not affect it because there is a dominant gene that masks the effect. If natural selection favours the recessive gene, the dominant gene will quite quickly disappear from the population. This does not make the recessive gene 'dominant' it's just tht there's no longer any competition. If selection favours the dominant gene however, the recessive gene can linger in the population for much longer, because even when it is present, it is not selected against for most of the time. That is why conditions like heamophilia survives for a long time in humans, and you suddenly discover a white deer after many years in a herd of brown deer.
What letters represent the alleles?
Dominant AllelesUsually dominant alleles are represented as capital letters, whereas recessive alleles are represented by the lowercase letter. Presumably, the capital letter will help you remember which is which -- dominant correlates with capital. However, you can assign alleles whatever letter, number, or symbol you want - as long as it produces the same genotype and phenotype ratio. The symbols/letters that are created for Punnett Squares or another process are purely for organizational purposes. Think of it this way: if you have a heterozygous organism that mates with a homozygous organism of the same species, how will you find the genotypes and phenotypes of the offspring? Well, you certainly aren't going to figure it out abstractly in your head. Assigning letters to dominant/recessive alleles is just to keep track of where the alleles are possibly going and the results. If you want the dominant allele to be "R" and the recessive allele to be "r", then that's perfectly acceptable. And if you want to represent the dominant allele with a Batman symbol and the recessive allele with a radioactive symbol, then that's fine too... as long as you know that the Batman symbol represents the dominant allele and the radioactive allele the recessive.
Question 7 of 10 Multiple Choice Please select the best answer and click submit. For a certain breed of cat short tails are dominant (T) and long tails are recessive (t). The Punnett square below show?
It seems like the question is incomplete, as it refers to a Punnett square that is not provided. However, in general, a Punnett square can be used to predict the genotypes and phenotypes of offspring based on the parental genotypes. If you provide the specific genotypes of the parents or the Punnett square details, I can help you determine the best answer.
For a certain breed of cat short tails are dominant (T) and long tails are recessive (t). The Punnett square below shows a cross between two parents. What is the phenotype ratio for this cross?
(Apex) 2 long, 2 short.
Can someone give you a List of dominant or recessive personality traits?

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 fraction of the progeny of the cross BbTt x BBtt will have black fur and long tails?
50% of the progeny will have black fur and long tails. This is because all of the offspring will inherit at least one dominant B allele for black fur, and 50% will inherit a dominant T allele for long tails.
Are tight eyelids a dominate or recessive trait?
Trait inheritance is more complex than a simple dominance or recessive model. The expression of eyelid tightness can be influenced by multiple genes and environmental factors, making it difficult to categorize as solely dominant or recessive.
If a mouse inherits a dominant gene for a long tail and a recessive gene for a short tail what tail length will the mouse have?
whatever type of tail it wants to.Answer: When a dominant gene is present, it will always be expressed. The only time a recessive gene is expressed is when no dominant gene is present. Therefore, the mouse in question will have a long tail.
How can you tell which one of your dog is recessive?
You can easily tell which is your dogs is recessive and which is dominant through observation. Some recessive behaviour is showing their stomach to the dominant one, licking the corner to the dominant dogs mouth, avoiding eye contact with the dominant dog, if the dominant dog growls the recessive one will back off, and following behind the dominant dog on walks, as in the wild the leader leads. If your dogs are fight it means they are challenging each others dominance to determine a pecking order. You should let them challenge each other as long as it doesn't turn onto a proper fight where one of them can get hurt.
Which letters are used for dominated and recessive characteristics?
Capital letters are often used for dominant characteristics and lower case letters are used for the recessive characteristics. The letter you use really doesn't matter as long as you follow the capitalization rules for the characteristics.
Is turner syndrome a dominant or recessive?
yes it is a recessive trait

If short hair (L) is dominant to long hair (I) ,animals with LL and Ll have the same?
LL and Ll will both express the dominant gene, in this case short hair. Only an animal with both recessive genes (ll) will have long hair.
How do cats use their long tails?
Cats use their tails for balance and like dogs, to communicate and show their "Pack Rank". A less dominant cat will hold her tail lower than the "leader".
For a certain breed of cat short tails are dominant (T) and long tails are recessive (t). The Punnett square below shows a cross between two parents. What is the phenotype ratio for this cross?
2 long, 2 short
