In metaphase, anaphase and telophase of meiosis 2 before cytokinesis the condition prevails.
Explanation:
Meiosis is the cell division process that occurs in gamete precursor cells to create gametes. It's a reduction division since the progenitor cells are diploid while the gametes are haploid.
During meiotic division, the cells first go through DNA replication that doubles the DNA content of each chromosome.
Then, via meiosis I, the cell experiences reduction division, transforming the diploid cell into a haploid cell. Thus, a cell with 10 chromosomes becomes one with 5 chromosomes. However, the DNA amount per chromosome remains doubled. This is corrected by the second meiotic division, where each chromosome splits into chromatids with a standard DNA content.
So at each stage of meiosis II,
until cytokinesis occurs, the cells should remain in a haploid state with double the DNA content. [[TAG_45]]
Response:
Este es un ejemplo de dominancia incompleta. Se trata de un fenómeno genético que se manifiesta cuando un gen dominante no logra expresar su totalidad en el alelo recesivo en un alelo heterocigoto dominante.
Por ende, ambos rasgos se muestran, dando lugar a una fusión de los dos alelos para los colores (blanco y rojo). El alelo rojo dominante muestra dominio parcial sobre el alelo blanco recesivo, produciendo así el alelo completamente rosado.
Según la ley mendeliana, las dos flores rojas son heterocigóticas. Por lo tanto, las flores rojas dominantes heterocigóticas deben ser R. El alelo blanco es recesivo (rr) y es enmascarado por el R rojo,
Sin embargo, al cruzar los dos alelos heterocigotos rojos:
Los fenotipos derivan en forma de
RR, (1) rojo Rr Rr (2) rosa rr (1) Blanco.
Esto ocurre porque el alelo rojo dominante no era total / completamente dominante sobre el alelo recesivo blanco en ninguno de los casos, resultando en un alelo rosa (el tercer fenotipo)
Response:
vaccine
bacteria
pathogens
cells
toxins
antibiotics
Clarification:
Bacterial meningitis is a severe infection leading to the Inflammation of the membranes surrounding the brain and spinal cord.
This infection is typically viral but can also be caused by fungi and bacteria. A vaccine is necessary to combat bacterial meningitis. Common signs include fever, neck stiffness, and headaches. It spreads through bacteria found in the throat of an infected individual and can be transmitted via coughing, sneezing, or kissing. The bacteria serve as pathogens that emit a toxin , which damages cells and components of the nervous system.
This condition is treated with intravenous antibiotics and corticosteroids in some cases.
Therefore, the correct sequential responses for the blanks are vaccine, bacteria, pathogens, cells, toxins, and antibiotics.
