Answer:
1/2 or 50%
Explanation:
B is dominant over b and T is dominant over t.
BbTt is crossed with BBtt
BbTt x BBtt = 4 BBTt, 4 BBtt, 4 BbTt and 4 Bbtt
4 BBTt = black fur with short tail
4 BBtt = Black fur with long tail
4 BbTt = Black fur with short tail
4 Bbtt = Black fur with long tail.
8 of the offpring have black fur with long tail while 8 also have black fur with short tail.
The proportion of offspring having black fur with long tail is 1/2 or 50%.
Answer:
Option (A).
Explanation:
Telomeres are the DNA sequences that are present at the end of the chromosomes. These sequences are replicated by the enzyme telomerase and prevent there shortening in each replication.
Telomeres sequences get mutated and multiply rapidly in case of cancers and used as an anticancer therapeutics. The telomere sequences are around 8,000-10,000 nucleotides long in the adult. The human born with around 10,000 nucleotides and get reduced upto 4,000 nucleotides as it reaches the old age.
Thus, the correct answer is option (A).
