Answer/ Explanation:
a. The genotype of a homozygous white eyed long winged female would be Vg+Vg+XrXr. We denote the white allele as recessive (r) because the XY male only has one copy and yet has red eyes, so the red eye trait (R) must be dominant. A homozygous red eyed vestigial winged male would have be VgVgXRY. The possible gametes for the female are Vg+Xr only. For the male, the possible gametes are VgXR or VgY
The attached punnett square shows the results of the cross. The females will all be Vg+VgXRXr. The males will all be Vg+VgXRY (must inherit Y from father). That means they will all have normal length wings, the males will have white eyes and the females will have red eyes.
b. The F2 flies arise from intercrossing the F1, so the cross will be Vg+VgXRXr x Vg+VgXRY. The possible gametes for the mother are: Vg+XR, Vg+Xr, VgXR or VgXr. The possible gametes for the father are Vg+Xr
, Vg+Y
, VgXr
, VgY
. The attached punnet square shows this cross. The ratio of the phenotypes will be 6:6:2:2, or 3:3:1:1 (long-winged red eye: long-winged white eye: vestigial wing red eye: vestigial wing white eye), genotypes shown in the attachment.
c. F1 cross back to the mother would be Vg+VgXRY x Vg+Vg+XrXr. The genotypes are shown in the attached punnet square. The offspring will all be long-winged with white eyes. The F1 to the father would be Vg+VgXRXr x VgVgXRY. The ratio would be 3:3:1:1 long-winged red eye: long-winged white eye: vestigial wing red eye: vestigial wing white eye

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.
