Answer:
22 map units
Explanation:
Linked genes may be defined as the genes present on the same chromosomes and they are inherited to the next progeny. The linked genes produces the recombinant progeny.
Distance between the linked gene = No. of recombinants / total number × 100.
Here the parental are 198 Tall Yellow, 192 Short Green.
The recombinant progeny are 54 Tall Green, and 56 Short Yellow.
Distance = 
Distance = 
Distance = 22 map units.
So, the distance between the genes are 22 map units.
Creating awareness will always be a solution , but doing something about it creates improvement to the global issue . You can create biodegradable plastics so whenever the biodegradable plastic hits the ocean , the object can become food for the ocean animals instead of harming them ......some McDonald’s are now changing their straws (biodegradable straws ) so change is happening slowly we just need awareness
ANSWER: CANCER DEVELOPMENT
EXPLANATION:
Tumor suppressor genes (TSGs) are genes that regulates the cell cycle of a cell (i.e the cell division and replication). In other words, TSGs encodes protein that act as control or regulator of cell growth.
However, when there is an alteration in the genetic sequence (mutation) of the TSGs, this make the cell not to respond to cues that had been regulating it growth.
Thus, when cell growth is not regulated, it results to runaway or abnormal cell growth (i.e multiple folds cell division and replication), in other word referred to as “cancer”.
With shorter necks, giraffe ancestors could not reach food-containing branches on tall trees. This resulted in the directional selection of giraffes with longer necks.
<h3>
Why is choosing a direction necessary? </h3>
It nearly appears obvious that the giraffe's long neck developed as a result of a lack of food in the lower branches of trees. The giraffe has a significant advantage because it is taller than any other mammal and can feed where few others can.
When compared to modern giraffes, the giraffe's ancient predecessors had a shorter neck. The plants that were lying at a higher level were inaccessible to them. Giraffe phenotypes have changed in various ways, and now have long necks to reach vegetation that is higher up. The extreme form is chosen above other features in directional selection. It was decided to choose the long-necked giraffe over the short-necked.
