||This is a metaphase spread of a female with [[Trisomy 21|trisomy 21]] (Down syndrome), though abnormal it is still a human genome (just not the normal human genome). It is not the normal female karyotype (number and appearance of chromosomes) and does not show the Y chromosome (as this is female XX). This is the most common human genetic abnormality and the additional chromosome is thought to occur due to incorrect meiosis.

You should try in your own time after completing the Practical today.


Take the Quiz

true
false

2 Which of the following statements is most correct about the human menstrual cycle.

The menstrual cycle in all women is a 28 day reproductive cycle
Ovulation always occurs at the midpoint of the menstrual cycle
The menstrual cycle's main function is to regularly replace the lining of the uterus
A high body temperature indicates ovulation is occurring
The menstrual cycle is an endocrine cycle regulating reproductive physiological changes

true
false

4 Which of the following statements is correct about the zona pellucida:

surrounds the oocyte in the ovary
