25%
Extra information:
Heterozygous means that the individual posesses two different alleles for a particular trait. Homogenous means that the individual posesses two similar alleles.Both parents are heterogeneous, which means that they have a recessive and a dominant allele. If you make a scheme, like the following:
A a
A AA Aa
a aA aa
you can calculate that the chances of the child (doesn't matter whether it is the first or not) has a chance of 25% to have two recessive (aa) alleles and therefore have Cystic Fibrosis.
The correct answer is "kidney dysfunction".
Physiologically, urea is filtered in the glomerulus in the kidneys. The urea in the blood is further secreted through out the renal tubules but more urea being reabsorbed than secreted. This results to 40% of the filtered urea present in the final urine. In the event of kidney dysfunction, there is destruction of the glomerulus or necrosis of the tubules. Therefore, urea is not efficiently filtered and excreted which will lead to high blood urea levels.
Answer:
Genetic engineering has multiple applications in different fields. Genetic engineering is the process by which alterations are made at the genetic level so that the final product is superior in quality and yield.
Explanation:
Following are few of it's applications:
<u>Medical field</u>- Genetic engineering is been used to produce insulin artificially, human growth hormones, anti hemophiliac factors, vaccines and other drugs.
<u>Agricultural industry</u>- It has been used to synthesize improvised crops which give better yield and are pest resistant. E.g Flavr savr, a species of tomato which is more juicy and larger in size than regular tomatoes.
<u>Environment</u>- With the introduction of herbicide resistant corn, farmers reduced the use of tractors which in turn reduced the amount of greenhouse gases. Also, by imparting disease resistance to plants, a lot of plants are prevented from dying. In addition, the biodiversity of an area can be maintained.
