If two individual are heterozygous for both traits then there genotype will each look like this PpLl. To find the probability, you need to do a cross with both traits. Each parent has the possibility of giving the following combinations: PL, Pl, pL, pl.
PL Pl pL pl
PL PPLL PPLl PpLL PpLl
Pl PPLl PPll PpLl Ppll
pL PpLL PpLl ppLL ppLl
pl PpLl Ppll ppLl ppll
Polka dot tail/ long lashes: 9/16
Polka dot tail/ short lashes: 3/16
Solid Tail / long lashes: 3/16
solid tail/ short lashes 1/16
The answer is (C) 9:3:3:1 ratio with 9 polka dot tails and long eyelashes, 3 polka dot tails and short eyelashes, 3 solid tails and long eyelashes (there seems to be a typo in the question) and 1 short tail short eyelash
The answer is chromosomes
Answer:
4 ul Loading Buffer + 19.70 ul dH2O + 0.30 ul DNA Ladder
Load 12 ul on the gel.
Explanation:
DNA Ladder concentration = 1000 ug/ml
1000 ug DNA in 1 ml DNA Ladder solution → 150 ng DNA = 0.15 ug DNA in..... 0.00015 ml = 0.15 ul DNA Ladder solution
6x DNA Loading Buffer → it has to be diluted by an equal volume 6 times (1 ul LB + 1 ul distilled H2O)
An appropriate volume to load on an average agarose gel is 12 ul, so:
2 ul Loading Buffer + 9.85 ul dH2O + 0.15 ul DNA Ladder = 12 ul
But since 0.15 ul is a very small volume and mistakes could be made while measuring it, let's make double:
4 ul Loading Buffer + 19.70 ul dH2O + 0.30 ul DNA Ladder = 24 ul
And load half of that solution (12 ul) on the gel.
