6. In Numbats, yellow bellies (Y) are dominant over green bellies (y).
a) Complete a Punnett square to show a cross between purebred vellow-bellied numbat
and a numbat that is hybrid for belly colour. What is the probability that the parents will
have yellow-bellied offspring?

b) Is it possible for two yellow-bellied numbats to have a green-bellied child? Identify the
genotypes of the parents and complete the cross on the Punnett square.
Genotypes of the parents:
and
If yes, explain how and identify what the probability would be.

The probability of the parents having yellow-bellied off-spring is 100% because all the genotypes have a dominant Y.

It is possible for two yellow-bellied numbats to have a green bellied child if they are both hybrid Yy. The probability of the parents to have a green-bellied child is 25%

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.
