Are tight eyelids a dominate or recessive trait?
It depends on the "lenght" of your eyelashes. If you have long eyelashes than it is dominant. If you have short eyelashes than it is recessive.
What is the difference between a homozygous trait and a heterozygous trait and can you please provide an example for each?
a homozygous trait is when an offspring has either both dominant genes or both recessive genes from its parents. a heterozygous trait is when an offspring has both dominant and recessive genes. for example: a long-tailed cat is dominant and a short-tailed cat is recessive. the long-tailed cat (homozygous dominant) had offsprings with the short-tailed cat (homozygous recessive). by doing the punnett square, 100% of their offspring will be heterozygous.
Is turner syndrome a dominant or recessive?
yes it is a recessive trait
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 jacobsen syndrome dominant?
Jacobsen symptom is neither dominant nor recessive because it is not a sex-linked disorder. This disorder is a mutation, specifically a partial deletion. Part of the long arm (q) of chromosome 11 is deleted.
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?
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

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.
Are lobe eyes a recessive trait in drosophila?
yes, vestigial wings are recessive and autosomal.
Which letters are used for dominated and recessive characteristics?
In genetics, dominant traits are typically represented by uppercase letters (e.g., "A"), while recessive traits are represented by lowercase letters (e.g., "a"). This notation helps geneticists distinguish between dominant and recessive alleles in a genetic cross.
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".
A dominant phenotype will only be expressed if the individual is homozygous dominant for that trait?
Well actually not necessarily. An individual can be homozygous or heterozygous dominant for a trait. As long as they have that dominant allele in that specific genetic trait, they will automatically express the dominant phenotype. If a person is homozygous dominant, it just means that they will pass on both dominant traits to the offspring. If a person is heterozygous dominant , it means that they will pass on both a dominant and recessive trait to their offspring.Hope that helps ! =D
