The woman have heterozygous (Dd) gene so she should have one dominant gene and one recessive gene. When her cells undergo meiosis, the gene would be split and the result of the child would be 50% cell with dominant gene and 50% cell with recessive gene.
Her child that have dominant gene will have 50% chance to inherit the dominant gene into the woman grandchildren. So, the total chance would be: 50% * 50%= 25%
It can be caused by mutation, random mating, random fertilization and recombustion between homologous chromosomes during meiosis.
Answer:
CH4 + 2O2 -----> CO2 + 2H2O.
Explanation:
CH4 + 2O2 -----> CO2 + 2H2O is the chemical reaction of burning of fossil fuels. The main difference between biomass and fossil fuels is that biomass is biological material which can be derived from living whereas Fossil fuel such as coal, oil and gas are derived from biological material. Biomass is renewable because a new crop can be grown after each harvest, and biomass is a low carbon fuel. Biomass is renewable just like other renewable energy sources because both can be used again and again. The energy choices locally occurs according to the availability of energy resources in that locality.
