If both parents are carriers of an recessive inherited trait, what are the chances that their child will express that trait?

Biology
1 answer:
ZanzabumX [31]3 years ago
5 0
The chances that the child will express that trait is 1/4 or 25%. Let the dominant trait be R and the recessive r.
A cross between Rr and Rr would yield RR, Rr, Rr and rr. Only RR would express the trait since its recessive.
Therefore chances =1/4 or 25%

You have a DNA sequence that codes for a protein and is 105 nucleotides long.A frame shift mutation occurs at the 85th base how
Anna [14]
In a DNA molecule, three nucleotides make up a codon. A codon is creates a specific amino acid. Therefore, in order to work this out, we must calculate the number of codons that will not be affected by the mutation. This is done by finding the highest number that is divisible by 3 but less than 85. This can be done by:
85 / 3 = 28.333
So 28 codons will not be affected.
