Answer: When a heterozygous guinea pig (Rr) is crossed with a homozygous guinea pig (aa), the possible genotype of the offspring contains Rr and rr. Each genotype has a 50% chance of occurring in a specific generation. Nine offspring can have smooth coats as heterozygous (Rr) and homozygous (rr) parents indicate low chromosome recombination frequency (in this crossover). Genes close together on the chromosome indicate low recombination; thus, the crossover would rarely happen.
Plants and other creatures utilize photosynthesis to convert light energy into chemical energy, which is then released to power the organism's metabolic processes through cellular respiration.
An undifferentiated cell is such as that in a blastocyte. They are multipotent and can differentiate into any type of cells. The cells of the mass begin to have their gene differentially expressed (due to differential silencing of particular genes) hence the cell become determined. They become well organized into tissue such as skin and other organs.
One of the benefits of a vegetarian diet is a reduction in your impact on the environment. Animals store only a small fraction of the energy they extract from the food they eat, and the rest is wasted as heat.
