Because for female sex link desease would require X°X° but for male X°Y so during crossing X linked dear are more common in male.
Whaaat.. I don’t understand that language..
Answer:
Explanation:
the advantages include:
disease and drought resistant crops that require fewer environmental resources for them to grow
higher yields harvested as the crops are not attacked by pests resulting in humans receiving more food as well as generating more money from the trading of their crops
increased supply of food at a cheaper life and the crops could have a longer shelf life
crops bound to be healthy as they ae not constantly treated by pesticides that could harm people
reduce the use of pesticides that might be a great move for the betterment of the food supply
they reduce the use of toxins that could harm the environment as well as the animals and people
disadvantages
unexpected or harmful genetic changes that could result in humans health being threatened
the process of genetically modifying the crops is quite expensive
due to the plants becoming pest resistant the pests are bound to have no food hence could die leading to some helpful pests such as beetles or ladybugs that actually benefit the environment going extinct
the production of genetically modified crops results in the disruption of biodiversity as you are favouring one specific organism hence resulting in the disruption of the natural gene flow
the crops are modified hence biotech foods may be a threat to the human health
Functionality of Genes and chromosomes is described below.
Explanation:
- Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes.
- Genes are contained in chromosomes, which are in the cell nucleus.
- A chromosome contains hundreds to thousands of genes.Every normal human cell contains 23 pairs of chromosomes, for a total of 46 chromosomes.
- A trait is any gene-determined characteristic and is often determined by more than one gene.Some traits are caused by mutated genes that are inherited or that are the result of a new gene mutation.
- The body produces thousands of different enzymes. Thus, the entire structure and function of the body is governed by the types and amounts of proteins the body synthesizes. Protein synthesis is controlled by genes, which are contained on chromosomes.
- the genotype is a complete set of instructions on how that person’s body synthesizes proteins and thus how that body is supposed to be built and function.
- The phenotype is the actual structure and function of a person’s body. The phenotype is how the genotype manifests in a person—not all the instructions in the genotype may be carried out (or expressed). Whether and how a gene is expressed is determined not only by the genotype but also by the environment (including illnesses and diet) and other factors, some of which are unknown.
- A karyotype is a picture of the full set of chromosomes in a person’s cells.
