Dad: TtBb

Mom: ttbb

You have to use distribution for dihybrid crosses.  Meaning, the first allele of each trait has a equal chance of being paired with the other allele of the other trait.  So for example with Dad, I will number the traits:

T(1)t(2)B(3)b(4)

To set up the possibilities from Dad, it would be 13, 14, 23, 24: TB, Tb, tB, tb.  Same idea goes for Mom, except since all alleles are the same, you only need to make one column for Mom, since if you did all 4, the other 3 would just be repeats of the 1.

Cross:

                 tb

TB           TtBb

Tb           Ttbb

tB            ttBb

tb            ttbb

A man of healthy weight may have, on the average, ____ percent of his body weight as fat.
Nat2105 [25]
The correct answer is 20% on average. The ideal percentage rate of a healthy man with normal weight is 18 to 22%. However, a range of 7-13% is considered normal for male professional athletes, because their muscular mass is much greater. The physiological minimum rate which is acceptable for males is 4-6%.

Atropine is sometimes used to dilate the pupil for an eye examination. which receptor would atropine block?
grigory [225]

Atropine would block the receptor called muscarinic acetylcholine receptors present in the eye.

Atropine is the Anticholinergic agent which is also known as parasympatholytics. The activity of neurotransmitters at the receptors leads to pupil constriction.

Atropine is used to block these receptors that allow the pupillary muscles to relax. This causes the dilation of the pupil.

Atropine is the mydriatics that is used for pupillary dilation to conduct a detailed examination of eye diseases.

without this medication, the pupil will only dilate in the darkness. However, doctors cannot examine the eye problems as there is darkness as they need light for checkups.
