In hamsters, an autosomal gene (F) controls solid coat pattern that is dominant over spots.  Another gene (E) is sex-linked, and controls the appearance of the tail.  Cotton-tail is recessive to a normal, straight tail. a)    A heterozygous, solid-pattern female, homozygous for normal tail is mated to a spotted, cotton-tail male.  What are the genotypes of the parents?  Use a Punnett square to diagram the cross and show the F1 genotypes.  b)    If a spotted, normal-tailed F1 female is mated to a F1 solid-pattern, normal-tailed male, what are the chances of obtaining a solid-pattern, cotton-tail male hamster?   

In determining the colour of watermelon fruit, let G represent the green colour and g represent the striped colour.  If two Gg plants are crossed, what is the probability of offspring with the homozygous recessive genotype?

What is the test of choice for diagnosis of retropharyngeal abscess?

A baby boy is born at 32 weeks, has respiratory distress, and is placed on CPAP. His x-ray taken 2 hours after birth shows low lung volumes and diffuse ground glass opacity. What is the most likely diagnosis?

A 1-year-old patient with respiratory syncytial virus (RSV) is receiving mechanical ventilation in the pressure control mode with the following current settings: PIP, 14 cm H2O; PEEP, 5 cm H2O; FiO 2, 0.50; respiratory rate, 28 breaths/minute. The patient has poor chest rise bilaterally, and breath sounds are underaerated with faint wheezes bilaterally. You notice that the measured tidal volume is 3 mL/kg and the respiratory rate is 80 breaths/minute. The patient has nasal flaring, retractions, and head bobbing. What should be suggested at this time?
