The karyotype of one species of primate has 48 chromosomes. In a particular female, cell division malfunctions, and she produces
Rom4ik [11]

Answer:

E) Either anaphase I or II

Explanation:

Failure of segregation of homologous chromosomes during anaphase I or failure of segregation of sister chromatids during anaphase II leads to the presence of the abnormal number of chromosomes in resultant gametes. In the given example, the egg mother cell with 48 chromosomes (24 pairs) would enter meiosis I but the failure of one pair of homologous chromosomes to segregate from each other followed by normal meiosis II would result in the formation of two gametes with one extra chromosome and two gametes with one less chromosome.

On the other hand, if the nondisjunction occurs at anaphase II of meiosis II, two normal gametes, one gamete with one extra chromosome and one gamete with one less chromosome will be formed. Therefore, nondisjunction at anaphase I or anaphase II would have resulted in the production of eggs with one extra chromosome.

Why do scientists belive that tectonic active is not accurring on the moon.
Roman55 [17]
<span>Scientists believe that tectonic activity is not occurring on the moon. This is <span>because the moon lacks radioactive decay. The moon is not constantly supplied heat and energy from decaying unstable isotopes like Earth. Also, Earth is heated by the original heat during its formation. Since the moon was most likely broken off from earth, it lacks this central heat. @Kb0812    Hope this helps and if your feeling generous feel free to leave a rate, thanks and brainliest because it would really help me reach expert and I would appreciate it ;)</span></span>
