Aparticular gene can have 2 forms, called alleles. which statement best describes the difference between the dominant allele and the recessive allele? a) only the dominant allele is expressed when the both allele are inherited b) only recessive allele is expressed when both allele are inherited c) the recessive allele is expressed only if it moves to a different chromosome d) the dominant allele can be expressed only if two homologous chromosomes have it

The correct option to show the simple allele relationship between them would be A. The dominant allele or the preferred DNA sequence is used to make protein more often than the recessive allele, if both are present.

Wetlands form where water and land meet. a lake with a wetland fringe can fill in with decayed plant and animal material to become a wet meadow. a pond can fill in to become a bog or fen. sediment can fill in a river marsh to become a swamp.flooding of coastal lowlands from rising sea levels has created broad coastal marshes that are protected from wave action by barrier islands or reefs. coastal wetlands also form when rivers deposit sediment as they reach the ocean. plants then take root and hold the soil firm against the forces of tides and waves.
