Fragile X syndrome is a result of the expansion of trinucleotide repeats. This means that a sequence of three nucleotides is uncontrollably multiplying in the X chromosome sequence, causing various health problems and deformities.

The correct answer is all of these.
Matter and energy on Earth are never destroyed or created out of nothing, but just transferred or converted to another form.
The inorganic matter is transferred to the living things from the physical environment by many biological processes like photosynthesis ( CO2), nitrogen fixation, absorption of the minerals by plant roots and many more.
Matter can then be transferred between different organisms through the food chain.
Eventually, the matter will return to the physical environment when organisms decompose and the cycle will start again.
1.why is it important for gametes to be haploid?
They fuse to form a diploid organism so there is a correct number of chromosomes
2. The inheritance pattern of one gene will not affect the inheritance pattern of another gene. This is known as
independent assortment
3. which of the following is a difference between phase I and phase II of meiosis?
Phase I results in two diploid daughter cells ans phase II results in four diploid daughter cells
4. what is heredity?
The passing of genetic information from parents to their offspring
