I hope this helps you!! :)
Answer:
1 or 100%
Explanation:
Let the allele for seed shape be represented by S.
True breeding spherical shape seeded pea plant will have SS as genotype
True breeding pea plant with wrinkled seeds will have ss as genotype
Crossing the two: SS x ss
Progeny: Ss, Ss, Ss, Ss
Based on the assumption that spherical shape allele is dominant over wrinkle shape allele, all the F1 offspring will have spherical seeds.
<em>Hence, the probability is 1 or 100%</em>
Random changes in allele frequency in a population are usually called genetic drift. The reason why this is the answer is because it is a very specific word which is used to describe exactly that - random changes in allele frequency.
All the other cases; answers, here aren't correct and don't apply.
