Each gene has a specific location (locus) on a chromosome and may come in several forms (alleles). genotype The actual genes for a trait present in an individual. genotypic ratio The expected numbers of different genotypes produced by a particular cross.
Bones are made from calcium. A typical bone has an outer layer of hard or compact bone, which is very strong, dense and tough. Inside this is a layer of spongy bone, which is â¦ like honeycomb, lighter and slightly flexible.
Bone is the supporting framework of your body. Most bones are hollow. The outer part of bones is a network of fibrous tissue called matrix onto which calcium salts are laid down. The hard outer layer of bones is made of compact (cortical) bone, which covers the lighter spongy (trabecular) bone inside.one is the supporting framework of your body. Most bones are hollow.
