Answer:
The correct answers are- a) In the deformed mice, somatic cells but not germ cells were mutated and d) The toxic chemical affects development but is not mutagenic.
Explanation:
Mutation in the somatic cells do not pass in the offsprings and the only mutation in the germ cells can pass to the offspring because offspring are produced by the fertilization between different germ cells. Somatic cell mutation can only cause deformation in individuals but their offspring will be like normal offsprings.
The other cause may be that the toxic chemical used don't cause any mutation but just affect the development of mice so in this case genetic material will remain in normal state in deformed mouse and they will able to produce normal offsprings. So the right answer is a and d.
The genotype will be NN, and the phenotype will be a large nose.
If this is a true or false question, the answer would be true. Hemodilution means an increase in blood plasma that would result in a dilution of the blood's cellular content.Hope this is the answer and would be of help.
