There is a change in amino acids sequence causes these mutations, If there is an error in the order of amino acids during the process of multiplication, there is a special enzyme to repair errors
Dominant refers to the relationship between two versions of a gene. Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked.

Answer:
Enzyme-controlled chemical reactions combining carbon dioxide and glucose water. The photosynthetic rate is affected by the temperature much like any other enzyme-controlled reaction.
Explanation:
At low temperatures, the number of molecular collisions between enzymes and substrates limits the photosynthetic rate. Enzymes are denatured at high temperatures.
Enzymes are protein molecules used in biological reactions by living organisms. The proteins are folded in a very specific form, which enables them to effectively bind to the molecules of interest. The enzymes used for photosynthesis perform less efficiently at a low temperature between 32 and 50 degrees Fahrenheit 0, 10, and 10 degrees Celsius, which lowers the photosynthesis rate.This will lead to lower glucose synthesis and slow growth. In the case of plants in a greenhouse, this is prevented by installing a greenhouse heater and thermostat.
The phenotype is - 75 % red and 25 %brown.
The genotype is hRhR - 25%
hBkhR - 50%
hBrhBk - 25%.
<h3><u>Explanation:</u></h3>
The cross given here is a simple dominant - recessive relationship between the three types of alleles of hair colour. The genes of this characteristics are present in autosomes, so will be segregated equally among all the sexes of the offsprings.
Now the genotype of auburn and red with black mother is given. So during gametogenesis, the gametes from the parents will be
Father - hBr and hR
Mother - hBk and hR
So, the probable combinations are hBrhBk, hBrhR and hBkhR.
The frequency of the combinations are 25%, 25% and 50% respectively.
The phenotypic ratio will be red : brown as 3:1.
