Hypothesize one way that a diploid organism could have offspring that are 3n or 4n
gladu [14]
Diploid refers to a cell that has two copies of each chromosome. One way that a diploid organism could have an offspring that are 3n (triploid) or 4n is when the chromosomes don't separate during meiosis.

Triploid refers to some cell that have 3 copies of each chromosomes for a total of 69 chromosomes.

In the universal ABO blood grouping system, there are four phenotypes—A, B, AB, and O—which are determined by three different al
charle [14.2K]

Answer:

The correct answer is - autosomal codominant inheritance (due to multiple alleles).

Explanation:

Autosomal codominant inheritance or codominance is a pattern of inheritance where the alleles present of an autosomal gene express their character in the phenotype. In other words, in this type of pattern, no allele would be masked by other alleles and both will be expressed in the phenotype.

The human ABO blood group is an example of this pattern as there are three alleles A, B, and O. In the heterozygous case of AB blood group both A, and B alleles expressed together however, O is masked by both alleles A, and O.

How does contour plowing in farming help to prevent pollution?
wel

D) Contour plowing is used to reduce erosion and sediment pollution.

Explanation:

Contour plowing in farming helps to prevent pollution by reducing surface erosion of topsoil and preventing sediment pollution.

Contour plowing is a farming technique in which crops are planted along the slopes of hills or contoured areas.

  • The rate at which rain water and precipitation moves along slope terrain is very fast.
  • This causes the washing off of the the topsoil on hills to eroded very fast.
  • Contour plowing breaks the slope and farming is done along movement on the contour.
  • This prevents topsoil erosion.
  • It also prevents sediment pollution in nearby streams and water bodies that are located around the valley at the base of the hill.

RSS<br>What happens in meiosis during telophase 2?​
ololo11 [35]

Telophase 2 is the final step of meiosis 2 in which homologous chromosomes reach the  opposite poles and four haploid cells are formed.

Explanation:

The telophase 2 ends up in four haploid (n=2) cells. It is in this phase the genetic material of the parent cell is divided into 2 daughter cells. The events taking place are nuclear membrane reappears (karyokinesis has taken place by now), spindle fibres and astral rays disappear, chromosomes decondensed to become chromatids (thin fibres), constriction on equatorial plate consequently four daughter cells formed.
