DNA BASE PAIRS:
adenine & thymine
cytosine & guanine
those are the pairs that go together
Answer:
25%
Explanation:
According to this question, a seek stored seeds of a rare and endangered plant. In order to ensure that the seeds remain fresh, 120 seeds are selected to be grown. However, out of these 120 seeds, only 90 germinated. This means that only 90 of 120 seeds are fertile.
This further means that (120-90) = 30 seeds are infertile and hence, could not germinate. In percentage, this can be represented as:
30/120 × 100
= 1/4 × 100
= 100/4
= 25% of the selected seeds are infertile.
Answer:
what is the probability of this couple having a child who is a non - roller ?
bb X Cc= bC, bc, bC and bc
The probability of the couple having a child who is a non-roller is 1/2
Explanation:
homozygous bb= non-roller father
heterozygous Cc= roller
From the crossing above we have equal halves of both roller and non-roller
1/2 roller
1/2 non-roller while the becomes heterozygous and roller is also heterozygous
