In the fruit fly, Drosophila melanogaster, a known deletion on the X chromosome removes both a gene involved in the fly's develo

pment and the gene for eye color. The deletion is lethal when homozygous or hemizygous. Flies that are heterozygous for the mutation are viable, but have indentations at the wing margin. Therefore, the deletion is named the Notch mutation. The allele for wild type eyes is dominant over the allele for white eyes.
Predict the phenotypic ratio of the offspring from a cross between a white-eyed notched female and a wild type male.
a. 1 white-eyed notched female 1 wild type female 1 notched male 1 white-eyed male
b. 1 wild type female 1 notched female 1 white-eyed male
c. 1 white-eyed female 1 notched female 1 white-eyed male
d. 1 wild type female 1 notched female 1 white-eyed male 1 white-eyed notched male

What is belief bias and what is the best way to avoid belief bias when making decisions?
zlopas [31]

Answer:

Belief bias is a conclusion where someone’s assessment of the logical strength of an argument is biased by the believability of the assumption. So for example, if you already have made up your mind that politician A is corrupt then the assertions made with no supporting evidence about politician A’s corruption is far more likely to be believed even though that belief can be wrong due to lack of evidence.

The best way to avoid belief bias when making decisions is to listen/consider the opposite view and listen to them, without being offended or getting angry.
