Since each parent contributes 1 allele to their offspring, we can expect a even distribution of 4 allele combinations in the offspring of these fish. They are
s1s2 = s1 from 1st parent, s2 from 2nd parent
s1s4 = s1 from 1st parent, s4 from 2nd parent
s3s2 = s3 from 1st parent, s2 from 2nd parent
s3s4 = s3 from 1st parent, s4 from 2nd parent
Since both the s1s4 and s3s2 offspring have 5 units of color, that would indicate that 50% of their offspring will have 5 units of color.</span>
Answer:
Each three base sequence of the mRNA, called a codon, is read by the ribosome, and the appropriate amino acid is inserted into the growing protein. If you have only a DNA sequence, to find the corresponding amino acids first transcribe your DNA sequence into an RNA sequence using complimentary base pairing.
Explanation:
B:-Leukemia is the answer.
Answer:
a. two plant species flowering at different times.
Explanation:
<em>The only option that is not a post-zygotic reproductive isolation mechanism would be option a, when two plant species flower at different times.</em>
Post-zygotic reproductive isolation mechanisms are those mechanisms that act to ensure that the product of fertilization remains invalid. This is as opposed to pre-zygotic isolation mechanisms that act to prevent fertilization and hence, formation of zygotes.
In option b, c, d and e; the zygote has been formed already and all the forces are just acting to ensure that it remains invalid. whereas in option a, there is no fertilization yet.
<u>Two plant species flowering at different times will ensure that there is no cross pollination between the two species. Without pollination, there cannot be a zygote formation.</u>
Hence, the correct option is a.
