andrew11 [14]3 years ago
7 0

chloroplast has a function in food production based photosynthesis. it receives light and c02 and produce glucose and water.

centrioles are the key factors in cell division. the create poles when a cell divides in two cells. many others activities are performed by them.

Use the information gathered in the Epistasis animation to answer the question. Although both dominance and epistasis involve ma
Dafna11 [192]

Dominance involves one allele masking another at the same locus whereas epistasis involves one locus masking a different locus.

Explanation:

Epistasis is a type of gene interaction in which one gene masks or modifies the expression of another gene at a distinct locus.

Dominance refers to the gene interaction in which one allele of a given gene masks the expression of another alllele of same gene.

The comparison of dominance and epistasis give the following  information:

  • Dominance  involves  allelic suppression while epistasis involves non-allelic suppression.
  • Dominance involves a single pair of alleles while epistasis involves two pairs of allele.
  • In dominance, the expression of recessive allele is suppressed while in epistasis, either recessive or dominant  non allele is suppressed.
  • The effect of dominance is due to the dominant allele while epistasis may be due to dominant or recessive allele.

Alex17521 [72]

Answer:

Binary fission is different from mitosis and meiosis because it occur in prokaryotic cells. And prokaryotic cells does not have nucleus like the eukaryotic cells and there is not mitotic spindle formation during binary fission compared to mitosis and meiosis.

Explanation:

Binary fission is a process of cell division where a single cells divide into two or more parts and the parts regenerate into another organisms which resembles the parent organisms. This occur only in prokaryotic cells and is very different from mitosis and meiosis that occur in eukaryotic cells because prokaryotic cells lack nucleus and no spindle formation in the nucleus.

Mitosis occur in eukaryotic cells because they have nucleus and membrane bound organelles and is the process where a parent cell divide to produce two daughter cells that are genetically identical to the parent cell and each cell having the same number of chromosomes of the parent cell.

Meiosis is a type of cell division that occur in eukaryotic cells and it occur in sex cells where a single cell divide into four daughter cells with each having half number of parent cell chromosomes.
