Answer: Incomplete dominance
Explanation: Incomplete dominance is a type of inheritance, specifically a type of intermediate inheritance when a dominant allele, or form of a gene, does not completely mask the effects of a recessive allele, and the organism’s resulting physical appearance shows a blending of both alleles. The result is a phenotype (expression) where the expressed physical trait is a combination of both of the phenotypes that belong to the alleles. One allele doesn’t mask or dominate the other alleles in this instance. It is also called semi-dominance or partial dominance.
In short, incomplete dominance is when neither gene is fully dominant, and the result is a brand new trait.
The Punnett square shows genetic inheritance as a simple model with only two different versions of alleles: dominant and recessive. In this simple relationship, dominant alleles always override the recessive alleles to be expressed in the organism’s appearance or phenotype. It was created by Gregor Mendel and was important because it contradicted popular ideas at the time that the traits of the parents were simply permanently blended within their offspring. However, modern biologists have discovered that inheritance isn’t as simple as this model would suggest.
An example of incomlete dominance in humans would be hypercholesterolemia.
Answer: 4 codon
Explanation:
We have two important data, that a molecule brought from Mars uses only three bases (A, C and T) and that it has 30 amino acids
Knowing that to encode 30 amino acids with 3 bases, you need to have 4 bases in your codon.
We have the possibility that having 4 bases can be encoded enough like this:
3 ^ 4 = 81.
however if we do the same procedure with 3 basic codons we will get an insufficient result
3 ^ 3 = 27
so the most likely codon number is 4
Water is the substance that does not use the aid of an active transport in the absorption of blood capillarities inside the kidney. An active transport would only be applicable if the molecule requires being transferred from an area lower concentration to the area of higher concentration across a membrane.
