What law best explains why an organism with Tt will show only dominant phenotypic?
The law that best explains why an organism with the genotype Tt will exhibit only the dominant phenotype is the Law of Dominance. This principle, established by Gregor Mendel, states that in a heterozygous genotype, the dominant allele (T) masks the expression of the recessive allele (t). Consequently, the presence of one dominant allele is sufficient to produce the dominant phenotype, resulting in the organism displaying that trait.
How do alleles interact in intermediate inheritance?
In intermediate inheritance, two different alleles at a single gene locus interact to produce a phenotype that is a blend of the two alleles. This results in a phenotype that falls between the dominant and recessive traits, rather than showing a clear dominant-recessive relationship. Both alleles contribute to the final phenotype in a co-dominant or blending manner.
Why is the IB allele dominant to the i allele?
The IB allele is considered dominant to the i allele because it produces a functional enzyme that adds the B antigen to the surface of red blood cells, while the i allele does not produce any antigen. This means that when both alleles are present (IBi), the B antigen is expressed, resulting in the phenotype associated with the IB allele. In contrast, the presence of the i allele does not affect the expression of the B antigen, making IB phenotypically dominant.
What phenotype is produced by AA genotype?
The AA genotype typically produces the phenotype associated with the dominant allele A. This means that the dominant trait will be expressed in the individual with this genotype.
If a gene has one completely dominant allele and one recessive allele how many different traits can these alleles produce?
A gene with one completely dominant allele and one recessive allele can produce two different traits in a population. Individuals with two dominant alleles (homozygous dominant) and those with one dominant and one recessive allele (heterozygous) will exhibit the dominant trait, while only individuals with two recessive alleles (homozygous recessive) will display the recessive trait. Therefore, the two traits produced are the dominant trait and the recessive trait.
Alleles that are neither dominant nor recessive produce an inheritance pattern known as .?
codominace
A homozygous dominant parent will produce a gamete with?
They will produce gametes that are also homozygous.
At least how many genes must interact to produce a trait?
At least _____ genes must interact to produce a trait.
Do oceans produce sugar instead of salt?
No, oceans do not produce sugar. They contain salt due to the presence of dissolved minerals like sodium and chloride. Sugar is produced by plants through the process of photosynthesis, not by oceans.
Which two combinations of allels could produce a trait controlled by a dominant allele?
with TT or Tt
