Albino people cannot make normal skin pigment, melanin. As a result, they have pale skin, white hair and red eyes. The diagram shows the pattern of inheritance of albinism over three generations of the same family. a) What is an allele? mark) (b) What is the evidence from the diagram that albinism is caused by a recessive allele! (3 marks) Using the symbols. A for normal coloration, healthy allele and a for the albinism allele: (c) Give the genotypes of both individuals in generation 11. (1 mark) (d) If there was a seventh child born in generation 3, what is the probability that he/she was born with albinism? Use a genetic diagram to work out your answer. (3 marks)

well, i believe that the answer is 2. : 3

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.
