Answer:
the answer to this question is single nucleotide insertion that changes codon groupings
Explanation:
In short, air pollution is foul air injurious to health. Air Pollution is anything that goes into the air that is harmful.Most air pollution is man-made. The largest contributor to airpollution is the burning of fossil fuels such as gas and coal. Someof the most common forms of air pollution are: Particulate matterNitrogen oxide (and other oxides of nitrogen) Sulfur oxide AcidRain VOC's (volatile organic compounds) Air pollution can also besaid as the accumulation in the atmosphere of substances that insufficient concentrations, endanger human health or produce othermeasured effects on living matter and other materials. Among themajor sources of pollution are power and heat generation, theburning of solid wastes, industrial processes, and, especially,transportation.
Answer:
1) In the first step, we need to predict the possible alleles for the cross. The dominant allele will be written with a capital letter. The recessive allele will be written with a small letter. Hence, the allele for brown hair colour will be B and the allele for red hair colour will be b.
2) In the second step, we need to determine the genotype of the parents. The genotype of the homozygous dominant parent will be BB. The genotype of the heterozygous brown hair colour will be Bb.
3) The punnet square for cross between these parents can be shown as follows:
B b
B BB Bb
B BB Bb
4) In the fourth step, lets determine the phenotype of the children. The phenotype of all the offsprings born will be brown hair colour.
5) The genotype from the punnet square shows that there is a 50% chance that the offsprings will be heterozygous dominant (Bb) for brown hair colour and their will be a 50% chance that the child born will be homozygous dominant (BB).
It happens during the s phase
