First, write out all combinations for the parents:
<u>SsBB</u>:
SB
sB
SB
sB

<u>ssBb</u>:
sB
sb
sB
sb

So now that you know what to put on as the x and y for the Punnett Square, set it up:

<u>     |    SB   |    sB    |   SB    |  sB     </u>
<u>sB | SsBB |  ssBB |  SsBB |  ssBB </u>
<u>sb | SsBb |  ssBb  |  SsBb |  ssBb </u>
<u>sB | SsBB |  ssBB |  SsBB |  ssBB </u>
<u>sb | SsBb |  ssBb  |  SsBb |  ssBb </u>

Now, listing each possible genotype and the number of times they show up in the square:
SSBB
0 times
SSBb/SSbB
0 times
SSbb
0 times
SsBB/sSBB
4 times
SsBb/SsbB/sSBb/sSbB/
4 times
Ssbb/sSbb
0 times
ssBB
4 times
ssBb/ssbB
4 times
ssbb
0 times

Since there are only 4 genotypes are possible, set up ratios of those four:

SsBB:
4 times/16 total = .25 = 25%

SsBb:
4 times/16 total = .25 = 25%

ssBB:
4 times/16 total = .25 = 25%

ssBb:
4 times/16 total = .25 = 25%

This means that the<em> genotypes</em> have a 25% : 25% : 25% : 25% likelihood.


Now, let's figure out the phenotypes of the 4 genotypes:
SsBB:
Ss = dominant
BB = dominant

SsBb:
Ss = dominant
BB = dominant

ssBB:
ss = recessive
BB = dominant

ssBb:
ss = recessive
Bb = dominant

So we have 2/4 that are S-dominant B-dominant and 2/4 that are S-recessive B-dominant.
This means that the phenotypes are:
2/4 = 50% Thin stripes with black eyes, and
2/4 = 50% Thin stripes with gray eyes.

I hope this helped you out :)

This group of enzymes digests the majority of ingested fat.
Kitty [74]

Answer:

Option A

Explanation:

Undigested fats include all those fatty acid and lipids which do not have the ability to dissolve in water. This inability makes them difficult elements for digestion. All this undigested fat accumulates and reaches the intestine for digestion as globs. Globs are emulsified by the bile salts and are broken down into smaller fat droplets. The smaller fat droplets have large surface area and hence now they can be acted upon by the fat-digesting enzyme pancreatic lipase. Thus, the first set of enzymes that act upon the undigested fats in the intestine are pancreatic lipase

Hence, option A is correct
