Dominant and recessive factors interact through the principles of inheritance, where dominant alleles mask the effects of recessive alleles in a heterozygous genotype. This means that if an organism carries one dominant and one recessive allele for a trait, the dominant trait will be expressed in the phenotype. Recessive traits only manifest when an individual has two copies of the recessive allele. Thus, the presence of a dominant allele can overshadow the influence of a recessive allele in determining observable characteristics.

What does it mean that an organism is homozygous dominant for a trait?
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)
Is folded tongue a reccessive or dominant?
The ability to fold your tongue is controlled by a dominant gene. If at least one parent can fold their tongue, their child is likely to also be able to do it.
How are autosomal disorders passed down?
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.
How did Mendel represent factors for dominant traits?
Mendel represented factors for dominant traits using uppercase letters, such as "A" for dominant alleles. This convention helps distinguish dominant traits from recessive traits, which are represented by lowercase letters.
What happens if an organism has two factors for a domintnat trait?
If an organism has two factors (alleles) for a dominant trait, the dominant allele will be expressed in the phenotype. This is because dominant traits mask the effect of recessive alleles, so the presence of two dominant alleles will result in the dominant trait being displayed.
What are heterozygous also called?
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
What does it mean that an organism is homozygous dominant for a trait?
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.
Mendel used what term to describe heterozygous pea plants?
He used the term hybrid.
When an allele mask the presence of another allele it is said to be?
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.
What color would baby's eyes be if both parents had brown eyes but grandmother had blue?
the baby will have brown eyes. this is because the gene for brown eyes is dominant, which means that it will always over rule a recessive gene (blue) eye gene and the only way a recessive gene could show up in a person is if there is no dominant gene present to push this gene out of the way. in other words, the only way the babyc ould have blue eyes is if both the parents had recccessive blue eye genes. however, you can be a carruer of a reccessive gene, as we have two genes of every kind. for example, one parent could have a dominant brown and a reccessive blue. but this wouldn't show in a person as blue is reccessive. get it? let me know if you need any more information on genetics. :)
How did Mendel represent factors for dominant traits?
Mendel represented factors for dominant traits using uppercase letters, such as "A" for dominant alleles. This convention helps distinguish dominant traits from recessive traits, which are represented by lowercase letters.
What is the definition of homozygous reccessive?
lowercase allele
Why do more people have attached rather than unattached earlobes?
The presence of attached or unattached earlobes is determined by genetics. The trait for unattached earlobes is dominant, meaning that it is more common in the population. This is why more people tend to have attached earlobes.
What is the unit of the biosphere called where nonliving and living factors interact?
They interact in the biosphere?
Is it possible for 2 homozygous recessive individuals to have a homozygous dominant child?
No, homozygous recessive indivuals MUST have two of the reccessive gene (bb), the possible combinations are bb,bb,bb,bb thus only a recessive trait is possible
