Answer:

Yeah, none of my teachers actually teach that’s why I use this.

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.

he burrowing owl is found in dry, open areas such as grasslands, prairies, savannas, deserts, farmlands, golf courses, and other
Arturiano [62]

Hey there!

A Burrowing owl's habitat is destroyed which is due to human activities and will come under Artificial destruction via human influence and not due to a natural destruction like cyclones, High Richter scale earthquakes, hurricanes with extremely high knot speeds, etc. Instead I'll say because of which the population of the burrowing owl will obviously decrease because they're more adapted to "their previous environment" and most likely "wouldn't adapt to a new unfamiliar environment".

To break these contradictions down simply said "they're unaware of the rules, regulations, type of soil, type of trophic levels, number of predatory organisms, etc. this makes it pretty hard to move from their once said naturally provided nature-made habitat to the burrowing owl, which got lost due to habitat annihilation by human cause. Further making the owls to adapt and change their "NATURAL TRAITS" to make it "CUSTOM" because of which these aren't going to help them instead they'd go either extinct by moving to a newly known unfamiliar habitat rather than their naturally nature gifted habitation.

So Yeah, the correct option [after the question mark ends] to be the least likely outcome would've been  "the population of species of burrowing owl maybe increase as per arriving in a new habitat or introduced to newly made surroundings". This is "Highly and the most unlikely" or the "least likely predictable outcome" for burrowing owls. Introduction of species to newer habitats without any prior training, kills the species and it's progenies.

Hope this helps  you and gives you the detailed analysis for this query for burrowing owls!!!!
