What type of dominance is a blending of the two alleles to make a phenotype somewhere between the parent’s phenotypes? a incompl
jekas [21]

Answer:

A. Incomplete dominance.

Explanation:

Incomplete dominance is the ability of two alleles to produce a heterozygous phenotype different from the two homozygous phenotypes.

Example is when a pure stock of red flowered (RR) four o'clock plant is been crossed with a white flowered(rr) one, the offspring are all pink flowered(Rr), showing a blending of flower colour character. Self pollination of the pink flowered F1 individual produce a mixture of F2 individual bearing red, pink and white flowers in the ratio of 1:2:1. This reappearance of the red flowered and white flowered forms in the F2 generation shows that alleles R and r have remained unaltered in the F1 generation.

If a mutation results in an organism with new characteristics, what might eventually be formed?
Temka [501]

If a mutation results in an organism with new characteristics then eventually a new species will be formed if more such mutations will continue to accumulate in the individual. Mutations result into the accumulation of variations in an individual and when such variations keep on accumulating in a particular organism consistently it leads to formation of a new species or we can say that evolution has occured.

Mrac [35]

Answer;

The mismatched pair is;

C) receptor proteins — bind with enzymes

Explanation;

- A receptor protein is a protein molecule that receives chemical signals from outside a cell. When such chemical signals bind to a receptor, they cause some form of cellular/tissue response, e.g. a change in the electrical activity of a cell.

-They are generally trans-membrane proteins, which bind to signaling molecules outside the cell and subsequently transmit the signal through a sequence of molecular switches to internal signaling pathways. There are two types of receptors: internal receptors and cell-surface receptors.
