<h2>Incomplete dominance & Co dominance</h2>

Explanation:

  • Twist- The mutant allele is prevailing to its relating wild-type allele.  
  • forked-the mutant allele is predominant to its relating wild-type allele.
  • Pale-The mutant allele is neither prevailing nor totally passive to its comparing wild-type allele.  
  • Mendel's outcomes were earth shattering halfway in light of the fact that they repudiated the (at that point well known) thought that guardians' attributes were for all time mixed in their posterity. At times,  the phenotype of a heterozygous living being can really be a mix between the phenotypes of its homozygous guardians.  
  • Closely identified with inadequate predominance is codominance, in which the two alleles are all the while communicated in the heterozygote.
  • Hence, the twist mutations are codominant allels at same locus.

A circular molecule of DNA contains 1 million base pairs. If the DNA synthesis at a replication fork occurs at a rate of 100,000
lakkis [162]

Answer:

<h2>5 minutes </h2>

Explanation:

1. In bidirectional replication;  there are two replication forks, and each proceeding at a rate of 100,000 (as given in the question) nucleotides per minute.  

2. So, by  the given rate of replication, we can calculate that, it would require 5 minutes for the circular DNA molecule to be replicated by bidirectional replication because each fork synthesize  500,000 nucleotides in 5 minutes ( 100,000 per minute) ( as given, in 5 minutes × 100,000 nucleotides per minute= 500,000 and by 2 forks= 1,000,000) within the time period.
