Answer:
All offspring are tall when a homozygous tall parent with homozygous short parent.
Explanation:
When we crossed homozygous tall parent with homozygous short parent, we conclude that all offspring are tall, because homozygous short parent are supressed under the homozygous tall parent, due to law of dominance.
Law of dominance states that, recessive alleles are suppressed by dominant alleles but they can appear in F2 generation.
Using a punett square, we can predict the cross between homozygous tall and homozygous short parent.
The phenotypes are: All are tall plants (4:0).
Answer:- 0.88
Solution:- Masses of silver and copper metals are given and we are asked to calculate the percentage of silver in the alloy.
mass percent of Ag =
Mass of Ag = 17.6 g
mass of Cu = 2.40 g
mass of alloy = 17.6 g + 2.40 g = 20.0 g
Let's plug in the values in the formula:
mass percentage of Ag =
mass percentage of Ag = 88%
So, the mass percentage of silver in sterling silver is 88% and in decimal form it is 0.88.
