Its Recessive
Homozygous Dominant for a trait means that an organism has two dominant alleles for that trait. Here's an example: Trait: Widow's Peak Widow's Peak allele: Dominant (D) No widow's peak allele: Reccessive(d) Homozygous Dominant (DD) Homozygous Reccessive (dd) Heterozygous (Dd)
the disorder is usually either autosomal recessive or autosomal dominant. they are passed down from the parents to the next generation. autosomal reccessive diseases only are when one parent gives one reccessive allele and the other parent gives the other reccessive allele. A dominant autosomal disorder can be inherited with one or two of the alleles.
no it is recessiveFamily studies clearly demonstrate that tongue rolling is not a simple genetic character, and twin studies demonstrate that it is influenced by both genetics and the environment. Despite this, tongue rolling is probably the most commonly used classroom example of a simple genetic trait in humans. Sturtevant (1965) said he was "embarrassed to see it listed in some current works as an established Mendelian case." You should not use tongue rolling to demonstrate basic genetics.No. Your mom is.
yes
Tongue rolling is homozygous dominant and all issue from this pairing will be tongue rollers. This is the only result that is allowable with a standard Punnett square or branch diagram representation. T = tongue roller t = non-tongue roller TT X tt = 4 Tt ======With tongue rolling expressed.
heterozygous genotypes are two different traits which one is reccessive and one is dominant. to be homozygous means that both the traits are either both reccessive or both dominant
Homozygous Dominant for a trait means that an organism has two dominant alleles for that trait. Here's an example: Trait: Widow's Peak Widow's Peak allele: Dominant (D) No widow's peak allele: Reccessive(d) Homozygous Dominant (DD) Homozygous Reccessive (dd) Heterozygous (Dd)

A dominant autosomal disorder can be inherited with one or two of the alleles.
He used the term hybrid.
Cause attached earlobes are the dominant trait. Unattached earlobes are reccessive.
It is twice the length of its tongue folded in half
Answer: Compressional stress.
Answer: Compressional stress.
Being able to roll your tongue is dominant, not being able to is recessive. Therefore, if you can roll your tongue, you have either a homozygous dominant gene for being able to roll your tongue, or a heterozygous gene. If you cannot, then you have a homozygous recessive gene.
It depends on what your trait is. Let's say that your trait was tongue roller. Rolling your tongue is dominant over non-tongue rollers so we would use R for Rolling your tongue. For the recessive trait, non-tongue roller, we use the same letter as the dominant trait except it is lowercase. So non-tongue roller would be r.
dominant is a genetic factor that blocks another genetic factor. recessive is a genetic factor that is blocked by the presence of a dominant factor.
Dominent. Simple- you have two types of Alleles, Dominent and Reccessive. Imagine a punnet square for the allele that causes albinoism (A). One parent has Aa, or one dominent allele and one reccessive allele for the trait. If the dominent skin-tone gene wasn't there (A), then it would be AA and he would be an albino. But since he has a dominent allele, he has normal color. If he made a baby with another Aa combination, they would have 25% chance of having an AA baby with no reccessive allele, a 50% chance of having an identical Aa combination, and a 25% chance of having an albino baby, AA.
