Why would it be important to know the possible genotypic and phenotypic ratios of different genetic crosses?

It’s important to know the possible genotypic and phenotypic ratios of different genetic crosses because the the phenotype shows what the offspring will physically look like what the genotype is what genes the offspring carries. phenotype doesn’t always show what alleles the offspring carries because if the offspring is heterozygous for the gene only the dominant allele shows and the recessive allele won’t be visible. the genotype can see what alleles the offspring carries, both dominant and recessive. knowing the genotype helps to know what alleles are passed on. if one of the parents have a genetic mutation that is passed on, the phenotype helps see what ration of offsprings will have the mutation visible and the genotype will help see what ratio of offsprings will pass on the allele for the mutation

probably isn’t useful. my brain is currently burnt

Nuetrik [128]

Answer:

1. Biological structure of the human body

The human body is organized in different levels according to their complexity.

The levels are the folowing (increasing complexity).

1. Atom (N, O, C,..)

2. Molecule (Protein, lipids, water...)

3. Organelle (mitochondria, golgi apparatus,...)

4. Cell (blood cells, bone cell,..)

5. Tissue (connective tissue, epithelial tissue,..)

6. Organ (lungs, kidney,..)

7. Organ system (skeletal system, muscuar system,...)

8. Organism (the human body)

Each of the levels is formed by an agrupation of the previous level. For example, cells are formed by a number of organelles, and a group of cells form a tissue.

Cells are the basic units of structure of the body, and there are different types of them.

2. Homeostasis

Homeostasis is a process of the body by which the organism works to maintain a stable internal environment, while adjusting to changes in the external environment.

This process is possible because of the work of both the nervous system and the endocrine system. While the first controles the body's activities and detects the necesity of adjustments, the second regulates the activities by using hormones.
