Paul [167]

Answer:

frequency of the blue (B) allele = 0.4142

frequency of the red (R) allele = 0.5858

The number of blue plants expected is 509.652

The number of red plants expected is 1019.304

The anticipated number of violet plants is 1441.341

Calculated chi square value

= 84.5320 + 42.5688 + 119.8692\\= 246.97

Explanation:

Frequency of blue allele is

Frequency of blue allele is equal to sum of frequency of BB and half of frequency of BR

\frac{302}{2970} + \frac{1}{2} \frac{1857}{2970} \\= 0.1016 + 0.3126\\= 0.4142

Frequency of other allele

1- 0.4142\\= 0.5858

Kryger [21]

It is the discomfort, inferiority, embarrassment, rejection, and disapproval we experience in our own skin when witnessing an act that we find repugnant, reprehensible, or pathetic on the part of another person.

<h3>Why is it that everything makes me cringe?</h3>

Cringe, according to developmental psychologist Phillipe Rochat, is an innate empathetic reaction of either scorn or compassion. One cannot cringe without having experienced the discomfort of an embarrassing situation, which is a requirement for an empathy reaction.

<h3>The cringe: How do you handle it?</h3>

You could do the following if you're cringing and criticizing yourself: resisting the want to recall the embarrassing situation. to divert your attention from the memories, engage in something else. telling yourself that what happened wasn't so bad or that nobody cares, so there's no reason for you to feel bad.
