Explanation:
The effect of chemotherapy that most patients have the hardest time dealing with is the hair loss which can be really demoralizing. In the example situation given in the question, the nurse should reassure the patient who is experiencing chemotherapy-induced alopecia (alopecia meaning hair loss) that his hair loss is temporary and that it will be the way it was before when the chemotherapy is over.

Answer:
Weaknesses of a test cross
- requires the observation of physical, phenotypic traits
- requires a sizeable number of offspring to give reliable results
- requires sometimes rarer, fully recessive individuals
- the maturation time in order to observe the phenotypes expressed may be lengthy.
Explanation:
In a test cross, the homozygous recessive genes for a trait are crossed with those the individual with an unknown genotype. The homozygous alleles are the same. The unknown individual is thus, dominant, and may be either heterozygous (different alleles) or homozygous.
In sexual reproduction, gametes are formed from the independent assortment of genes. The parental genes are packaged together in new combinations. Thus, to determine an unknown, the test crosses determine which is the parent genotype through its ratios:
- a homozygous dominant parent produces all heterozygous offspring
- a heterozygous dominant parent produces homozygous and heterozygous offspring
However, the phenotypes must be observed to give results of this cross.
The simple answer is mucous cells. the stomach is lined with gastric mucosa and the intestine is lined with intestinal mucosa.
