It seeks to understand how and why people‚ all kinds of people‚ everywhere‚ of every age‚ change overtime. 3. Why have recommendations regarding the sleeping circumstances of infants changed? Every year until the mid-1990‚ thousands of 2 to 4 month olds died of SIDS. Susan Beal hypothesized that sleeping position might matter‚ as a result‚ SIDS rate dramatically decreased.

Sex determination in plants Summary- Evolutionary transitions happened gradually from hermaphroditism to monoec in which multiple sex determining genes are involved which include male-sterility and female-sterility factors. There should not be any recombination between different loci which is the pivotal reason for the genetic degeneration of Y chromosomes. There are several theories attached to Y chromosome degeneration that are reviewed recently . Introduction: why are plant sex chromosomes

was‚ which is the first step in evolution. Mutations are chance alterations in an organism’s DNA that causes their genetic makeup to change. Mutations can affect a population as a whole but also affects the individual‚ whose mutated genotype may affect its phenotype‚ causing it to become different from it’s grorup. Natural selection will either allow this individual to live and reproduce (if the mutation is beneficial) or cause it to die due to its genetically induced lack of fitness. Migration occurs
