The global air temperature increases after the volcanic eruptions. It has also been observed that this increase in air temperature causes lowered winter seasons, acid rain, haze, dust, and ash. This causes problems in breathing and other disorders in humans as well as animals.
Answer:
The combinations of gametes that could be produced from heterozygous individuals for both traits are PT, Pt, pT and pt.
Explanation:
An individual is heterozygous for two traits, flower color and stem height, with a PpTt (dihybrid) genotype and a phenotype showing the dominant traits, purple flowers and tall stem.
The genes of this individual for the above-mentioned traits contain different alleles, and taking into account the independent segregation of characters, the alleles present in its gametes could be:
- <em>Both dominant alleles: PT
</em>
- <em>One dominant and one recessive allele Pt or pT
</em>
- <em>Both recessive alleles: pt
</em>
Therefore, the traits of its offspring will depend on the alleles for those traits present in the gamete to which they are combined.
Answer:
B.) Anaphase II
Explanation:
In metaphase II, the chromosomes line up individually along the metaphase plate. <u>In anaphase II, the sister chromatids separate and are pulled towards opposite poles of the cell.</u> In telophase II, nuclear membranes form around each set of chromosomes, and the chromosomes decondense.
the genetic material housed inside the cell nucleus is packaged in into these organized bundles.
- chromosomes
