A carrier of a genetic disorder who does not show symptoms is most likely to be heterozygous for the trait and able to transmit it to offspring. This particular individual has inherited a recessive allele for a genetic trait or mutation but does not display that trait or show symptoms of the disease. They are referred to as genetic carriers. The chance of two carriers having an offspring with the disease or genetic disorder is 25%
Answer:
Continuous variations are formed due to chance segregation of genes during gamete formation, crossing over and chance combination during fertilization. They can increase adaptability of the race but cannot form new species.
