What is the probability that a corn plant with the genotype rr crossed with a corn plant rr will have offspring with the genotype rr? express your answer as a fraction using numerals for numbers and / for the fraction bar. do not include spaces. submit

50/100. When solving for an offspring you Look for a dominant if there's a dominant it'll reduce the chance for the offspring to be a recessive. But it'll be a 50% Because the recessive also has a chance to be the final offspring.

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.
