They determine the north and south ends
Answer:
The genotype of the F1 was wy+/w+y.
Explanation:
One of the given options has a typo: the red eye-brown body offspring count should be 56 instead of 561.
<u>We have two genes with two alleles each:</u>
Red eyes (w+) is dominant over white eyes (w).
Brown body (y+) is dominant over yellow body (y).
The phenotypes of the F2 tesulting from a test cross (F1 x wy/wy) are:
- wy+/ey (white-eye, brown body): 670
- w+y/wy (red-eye, yellow body): 650
- wy/wy (white-eye, yellow body): 38
- w+y+/wy (red-eye, brown body 56
If the genes w and y are linked, two phenotypes in the F2 will be much more abundant than the other two. Recombination during meiosis is a rare event, so the most abundant phenotypes are the parentals (the ones present in the F1 parent).
Every individual in the offpsring has a <em>wy</em> chromosome, as this was the gamete inherited from the test cross individual.
In this case, the most abundant gametes are wy+ and w+y, so the genotype of the F1 was wy+/w+y.
Notice how when recombination occurs in the F1 parent, the recombinant gametes appear: wy and w+y+, which are the less abundant in the F2 progeny.
Unintentional learning occurs when behavior is modified through a consumer-stimulus interaction without any effortful allocation of cognitive processing capacity toward that stimulus
This suggests that user behaviour may vary based on how sensitive they are to information that was not available to them when they conducted the previous study.
This occurs as the behaviour is altered in response to the stimulus via a consumption-stimulus relationship without the arduous allocation of cognitive capacity.
<h3>What is Unintentional learning ?</h3><h3 />
Learning that happens accidentally as a result of activities when the learner has no deliberate objective of learning is known as incidental learning. Incidental learning occurs, for instance, when someone plays a sport for enjoyment yet gradually develops their skills.
