Nondisjunction is when homologous chromosomes fail to separate properly during meiosis. What are some of the side affects of this occurring. Is there a way to detect this problem?
- Recombination Occurs By Physical Exchange Of Dna
KEY TERMS:Crossing-over describes the reciprocal exchange of material between chromosomes that occurs during prophase I of meiosis and is responsible for genetic recombination. A bivalent is the structure containing all four chromatids (two representing...
- Homework- The Ethics Of Genetic Screening
Genetic screening already allows us to detect certain genetic disorders and the sex of an embryo or the fertilised egg in IVF treatment. As genetic testing progresses it may enable us to detect lots of characteristics. This raises the ethical question...
