Question

How many phenotypic classes do you expect to observe from the trihybrid test cross you established previously (assuming Mendelian segregation & independent assortment?

a. 256

b. 6

c. 8

d.16

2. a genetic is based on : __________ between genetic loci

a. recombination frequency

b. phenotypic variation

c. alphabetical order

d. genotypic variation

e. the number of nucleotides (bp)

physical map is constructed on : ________ between genetic loci.

a. recombination frequency

b. phenotypic variation

c. alphabetical order

d. genotypic variation

e. the number of nucleotides (bp)

Explanation / Answer

1-option c is correct because in trihybrid cross 8 different phenotypic class observe.

2-option a is correct because genetics is based on the variations which occur by recombination.

3-option e is correct because physical map is based on the actual number of nucleotide pait between loci.
