Read the scenario carefully. What generated the error that results in trisomy X?
Nondisjunction resulted in gametes with an
abnormal number of chromosomes.
O An error during mitosis caused a mutation in
gamete DNA, resulting in an extra chromosome.
A somatic mutation after fertilization of the gametes
generates trisomy X.
This error generated during embryonic growth as
germ layers started to differentiate.

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.
