Incomplete Dominance and Codominance You are studying leaf development in a member of the mustard family. You identify several m

utants of interest in this plant and make pure (true-breeding) lines of each mutant for further study. Part A - Determining relationships between alleles You decide to conduct a genetic analysis of these mutant lines by crossing each with a pure wild-type line. The numbers in the F2 indicate the number of progeny in each phenotypic class. From these results, determine the relationship between the mutant allele and its corresponding wild-type allele in each line. Label each mutant line with the best statement from the list below. Labels may be used once, more than once, or not at all.

<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.

Troyanec [42]

Answer:

0.96

Explanation:

It is given that

B is the dominant allele which represents the black color

and b is the recessive allele which represents the white fur.

B being dominant will result into black color fur for genotype "Bb"

Given -

Frequency of black fur allele (p) is 0.8

As per Hardy Weinberg's  first law of equilibrium

p + q = 1\\

Substituting the value of p in above equation, we get -

q = 1-p\\q = 1-0.8\\q= 0.2

q represents the frequency for white fur allele

Frequency of white fur phenotype is

q^2\\= 0.2^2\\= 0.04

Frequency of homozygous black fur phenotype (BB) is

p^2\\= 0.8^2\\= 0.64

As per Hardy Weinberg's second law of equilibrium -

p^2 + q^2 + 2pq = 1\\0.64 + 0.04 + 2pq = 1\\2pq = 1 - 0.68\\2pq = 0.32\\

Combined frequency of homozygous and heterozygous black fur phenotype is

0.64 + 0.32\\= 0.96

Explain how the use of Restriction Fragment Length Polymorphisms to diagnosis genetic disease differs from its use in forensic i
saw5 [17]
RFLP or Restriction Fragment Length Polymorphism exploits the variation of homologous DNA (Deoxyribonucleic Acid) sequences. This technique is frequently used in different types of analysis such as genotyping, paternity tests, forensics, hereditary disease diagnostics, and many others. In diagnosing diseases, PCR is use to find the DNA of pathogens in small amounts to diagnose hundreds of genetic diseases. While in forensic investigations, PCR can give a probably ID from 20 cells.
