Nady [450]

Answer:

The food chain is formed by the organisms beginning from producer and ending in tertiary consumer based on their feeding habits. A complex network of food chains in a community forms the food web. Any disruption of the food web would result in ecological imbalances.

Explanation:

A festive PC of large snakes means huge number of large snakes which generally occupies the apex position in the tropical community. The snakes being carnivorous would feed on primary herbivores, carnivores, as for example, frogs, insects, dogs, cats and so on. The food web would be completely disrupted causing increase in vegetation part of the food web, that is the number of plants and trees will be showing a huge surge. Gradually a time will comes when these large snakes being carnivorous would have nothing to feed and these snakes wouldn't survive.

For all questions, assume that you have genes for beak color, tail-feather length, and feather color all linked (located) on the
Effectus [21]

1. If we cross YyLl (heterozygous parent with dominant traits) with yyll (homozygous parent with recessive traits)

P:  YyLl  x  yyll

F1 generation: YyLl: 400 Yyll: 100 yyLl: 100 yyll: 400

Recombinant offspring are those children whose genes contain a non-parental allele combination  (neither allele group is directly inherited from either parent). This happens when genes are located on the same chromosome but are so far apart from one another so that their alleles get crossed over during meiosis. In this case, Yyll and yyLl are the recombinant.

2. Calculation of distance between Y and L.  

The numbers of the two recombinant types is 200 (100 Yyll + 100 yyLl) and 800 parental offspring.

Total number of offspring is 1000.

So: 200/1000*100=20 map units.

There is 20 percent recombinant offspring frequency.
