An ischemic stroke is the sudden loss of blood flow to an area of the brain. It results in loss of neurological function.
Ischemic stroke involves the obstruction of blood flow within the brain. The obstruction can be caused by a thrombotic or embolic occlusion of an artery in the brain.
The answer is heterozygotes. Heterozygote offspring inherited different forms of a specific gene from individual parents. In a homozygous genotype, the offspring inherited same form of a specific gene from each parent.
Answer and Explanation:
<u><em>Note</em></u><em>: In the attached file you will find the pedigree and the genotypes of each member. </em>
Parentals) XDXd x XdY
- The female is heterozygous for the trait, transmitting the mutant allele
- The male is not affected.
According to the pedigree, they had the following progeny:
- XDXd affected female (this individual transmitted the mutant allele)
- XDY affected male (this individual transmitted the mutant allele)
-Both healthy individuals mated with another two healthy individuals. Their whole progeny was healthy.
-The affected female (XDXd) mated with a healthy male (XdY), and they produced 100% healthy individuals
-The affected male (XDY) mated with a healthy female (XdXd) and they had three affected females, XDXd.
Here the genetic engineering using insulin gene is done.
<h3><u>Explanation</u>:</h3>
Genetic engineering is the process by which an eukaryotic gene is isolated and is attached with a plasmid and inserted into the bacterial cells for the production of that protein and further utilisation of that protein. A plasmid is the extranuclear DNA that is present in some bacteria.
Here the insulin gene is isolated from the human cell, then it's attached with the bacterial plasmid and inserted in the fresh bacteria. This will lead to production of Insulin. This insulin is extracted, purified and can be used to treat diabetes mellitus. Thus, this is an example of Genetic Engineering.
