<span style="font-family: "trebuchet ms" , sans-serif;">Los cromosomas se clasifican en autosomas y cromosomas sexuales (gonosomas, sexocromosomas, heterocromosomas). De acuerdo al aspecto que adoptan debido a las cadenas de material genético que presentan en los diferentes momentos de la división celular se les puede dividir en monadas, diadas y tetradas (esta última disposición durante la profase I de la meiosis). </span></div>
<div style="text-align: justify;">
<span style="font-family: "trebuchet ms" , sans-serif;">También se pueden clasificar de acuerdo a la posición del centrómero. De acuerdo a esto, ¿cuál es la denominación de cada cromosoma representado en el esquema?</span></div>

(neuronas, hepatocitos, células epiteliales, musculares, etc.) reciben esa
denominación por constituir la inmensa mayoría del cuerpo. En condiciones
normales, su núcleo <strong>SIEMPRE </strong>tendrá 46 cromosomas, o sea 23 pares (22 pares de
autosomas y un par de cromosomas sexuales o heterocromosomas). A esto se le
denomina número <strong>DIPLOIDE </strong>y se representa como 2n.</span></div>

que sin importar que la célula se divida, y para ello duplique el material genético durante la fase S
del periodo de Interfase, las células somáticas nunca tienen más de 46
cromosomas. Tras la fase S, aún tienen 46 cromosomas (2n) solo que duplicados,
es decir, como <strong>DIADAS</strong>, que al dividir su centrómero en la anafase de la mitosis,
permitirán que cada una de las dos células hijas sea genéticamente idéntica a
la célula madre. Por ello se dice que tras la fase S, las células presentan
2n4c, o sea los 46 cromosomas pero con 2 cromátides por cada uno (relación 1:2)
y tras la división vuelven a ser 2n2c, o sea los mismos 46 cromosomas pero con
una cromátide por cada uno (relación 1:1).</span></div>
