Answer:
- 120 individuals yySs
- 60 individuals yyss
Explanation:
<u>Available data</u>:
- Two autosomal diallelic genes Y and S
- Y is the dominant allele that codes for yellow
- y is the recessive allele that expresses black
- S is the dominant allele that expresses stars
- s is the recessive allele that codes for starless
- Lethal genotypes: YYss and yySS
1st cross: A true-breeding yellow star bellied sneetch with a true-breeding black starless sneetch
Parentals) YYSS x yyss
F1) 100% YySs
N = 50
2nd Cross:
Parentals) YySs x YySs
Gametes) YS, Ys, yS, ys
YS, Ys, yS, ys
Punnett square) YS Ys yS ys
YS YYSS YYSs YySS YySs
Ys YYSs YYss YySs Yyss
yS YySS YySs yySS yySs
ys YySs Yyss yySs yyss
F1) N = 840
- 14/16 survivers
- 2/16 death YYss and yySS
- 9/16 yellow with stars
- 2/16 yellow starless Yyss
- 2/16 black with stars yySs
- 1/16 black and starless, yyss
14 ------------------ 100% of the progeny --------------840 individuals
2 yySs -----------X = 14.28% ------------------------------X = 120 individuals yySs
1 yyss ------------X = 7.14% ------------------------------X = 59.97 individuals yyss
The ridge produces magma at a steady rate so when the poles change and the crystals switch in the rock it changes to opposite of the old rock.
I think you would be more interested in the location's weather than the climate because if you are wanting to get away from the winter cold for awhile then you would probably plan to go somewhere close to the equator, where it is warmer. A location's weather could be scattered or generally misinterpreted as weather can be random at times.
Regardless, for the chemical equation to move accurately, energy/sunlight should be add on the top of the arrow.
