Explanation:
Answer:
Genes coding for proteins involved in chiasma formation.
Explanation:
Chiasma is the connecting link between two non sister chromatids from homologous chromosomes. At chiasma chromosomal crossover takes place in which the genetic material is exchanged between the chromatids. During meiosis aneuploidy occurs if chiasma is absent or impaired due to a mutation in genes encoding for proteins involved in chiasma formation.
Aneuploidy is characterised by presence of abnormal number of chromosomes in cells. They can be 45 or 47 in number apart from the usual 46. Due to impaired chiasma, chromosome pair fails to separate and is passed on to the egg or sperm as it is hence there is one gamete with an extra chromosome and one gamete with a less chromosome. Aneuploidy can result in many genetic disorders like three copies of chromosome 21 can result in Down syndrome.
Answer:
Mirrors are essential to every home. They help us in our daily mundane lives, though we rarely ever really appreciate their usefulness. From the moment we get up at night to the time we ready ourselves for sleep, we almost always seek for a mirror to take a look at ourselves. Mirrors reflect to us how we look, how clothes fit us, and how things fit.
Explanation:
Answer:
Skeletal muscle decomposes more slowly than internal organs and nerve tissue after death, but still more quickly than cartilage and bone.
Together, these factors make muscle tissue a good candidate for postmortem change study and well-suited for standard forensic lab examination.
