A dihybrid cross produces 30 recombinant offspring out of a total of 1,000 offspring. What is the recombination frequency of the
uranmaximum [27]

The recombination frequency of the two gene pairs is 3%.

The number of recombinant offspring(r.o.) / total number of offspring x 100% = recombination frequency(θ):

r.o./total x 100% = θ

30/100 x 100% = 3%

Recombinant offspring are children that have a different allele combination to their parents.

For example, say a mother has a haploid cell with the alleles AB and the father has a haploid cell with the alleles ab. These combine to make a diploid cell with the sequence Aa+Bb.

Formation of Recombinant Offspring :

Recombination can happen in two different ways; independent assortment and crossing over.

  • Independent assortment is when the maternal and parental DNA are mixed during meiosis, creating a new gene sequence.
  • Crossing over happens during the first stage of meiosis when the two homologous chromosomes are paired and a portion breaks off on the same loci then reconnects to a different end. Crossing over can only happen when there isn't a physical linkage of the parental alleles.

Recombination frequency (θ) is the frequency with which a single chromosomal crossover will take place between two genes during meiosis. A centimorgan (cM) is a unit that describes a recombination frequency of 1%. In this way we can measure the genetic distance between two loci, based upon their recombination frequency. This is a good estimate of the real distance. Double crossovers would turn into no recombination. In this case we cannot tell if crossovers took place. If the loci we're analysing are very close (less than 7 cM) a double crossover is very unlikely. When distances become higher, the likelihood of a double crossover increases. As the likelihood of a double crossover increases we systematically underestimate the genetic distance between two loci.

When two genes are close together on the same chromosome, they do not assort independently and are said to be linked. Whereas genes located on different chromosomes assort independently and have a recombination frequency of 50%, linked genes have a recombination frequency that is less than 50%.

vovangra [49]
Given the age of the meteorite is 4.5 billion years old with 78 atoms of lead-206 the answer should be B. 156. The half-life of uranium-238 in order to decay into lead-206 is 4.46 billion years, which means that the original number of atoms is 156.

38. the anterior portions of the nasal cavities just inside the nostrils are known as the ____.
max2010maxim [7]

The anterior portions of the nasal cavities just inside the nostrils are known as the Vestibules

<h3>What are nasal vestibules? </h3>
  • The nasal vestibule is the area just inside the nostril (nose opening) that leads into the nasal cavity.
  • The nasal vestibule contains cartilage of the nose and is lined with tissue that contains small, course hair. These hairs help filter dust, sand, and other particles to stay them from entering the lungs.
  • The vestibule of the traditional adult nose is a specialized organ with very characteristic structures and specific functions and is the beginning of each nasal passage. Here the tract makes its first contact with the outside world of air.
  • The vestibule is surrounded almost entirely by its half the nasal lobule, bounded laterally by the ala, or wing, medially by the mobile septum and columella, superiorly by the cul-de-sac and limen vestibuli, and posteriorly by the skin lying on the alveolar ridge of the superior maxilla
