Answer:
homo-zygous lethal dominant
Explanation:
A homo-zygous lethal pattern is a type of inheritance where an allele is lethal in homo-zygous individuals. In normal dominance, the expected genotype ratio when F1 heterozygous individuals are crossed is 1:2:1 (i.e. 1 homo-zygous dominant: 2 heterozygous individuals and 1 homo-zygous recessive), while the phenotypic ratio is 3:1 (3 individuals expressing the dominant allele: 1 individual only expressing the recessive allele). In this case, the homo-zygous lethal allele changes the expected F2 phenotypic ratio to 2:1 (i.e., 2 heterozygous singing Beetles : 1 homo-zygous recessive non-singing Beetles), where the partially dominant allele is lethal in homo-zygous individuals.
It is true.
The organism will die at a faster rate. <span>The competitive exclusion principle states that no two organisms can occupy exactly the same niche in exactly the same habitat at exactly the same time. This is also true according to several online sources.</span>
The answer is A. to see if samples contain the same DNA.
When an allosteric enzyme is directly affected by a molecule that is not its substrate, this effect on the enzyme is called a heterotropic effect.
<h3>What is an allosteric enzyme?</h3>
Allosteric enzymes are catalysts that exhibit a site for binding that is distinct from the active site.
Allosteric enzymes are controlled by many effector compounds that can bind to different sites.
The active site of the enzyme is the molecular domain of this protein where reactants can bind during a chemical reaction.
The heterotropic effects occur when the ligands of allosteric modulators (effectors) are linked to the enzyme.
An allosteric modulator is a molecule that binds to the enzyme in a site different to the active site and this binding alters its tridimensional conformation, thereby activating it or deactivating it.
In conclusion, when an allosteric enzyme is directly affected by a molecule that is not its substrate, this effect on the enzyme is called a heterotropic effect.
