In asci, the products of meiosis are present together as
tetrad.
In the first division segregation pattern, also known as MI
pattern, there will be crossing
over between the gene and the centromere. Simultaneously the two
alleles segrergate in first
division into two distinct nuclei. This results in production of
2:2 pattern.
Similarly, in the second division segregation pattern, also known
as the MII pattern, there
will be a crossing over between the gene and the centromere.
Simultaneously the two alleles
separate out into distinct nuclei inthe second division.
This produces the 2:2:2:2 patterns.
What is first division segregation pattern type as opposed to second division segregation type in asci
1) Are ascospores produced by meiosis or mitosis? Explain your reasoning 2) Describe first division and second division segregation.

Gametes are produced with extra chromosomes. c. Half of the gametes produced are wild-type, whereas half are mutated. d. Sister chromatids fail to separate. e. Gametes are produced with missing chromosomes.
Accounting Information System What is meant by the term “segregation of duties control” (sometimes referred to as the “separation of duties control”). Discuss fully. In your explanation discuss the “how”, “when”, “where” and “why” of the segregation of duties control, and some of the limitations or disadvantages of this type of control. You can provide examples to illustrate your explanation.

1. A single slit forms a diffraction pattern, with the second minimum at an angle of 40.0° from central maximum, when monochromatic light of wavelength 630 nm is used. What is the width of the single slit? 2. Consider a two-slit experiment in which the slit separation is 3.0 × 10-5 m and the interference pattern is observed on a screen that is 2.00 m away from the slits. The wavelength of light passing through the slits is 420 nm....
A single slit forms a diffraction pattern, with the first minimum at an angle of 40.0° from central maximum, when monochromatic light of 590-nm wavelength is used. The same slit, illuminated by a new monochromatic light source, produces a diffraction pattern with the second minimum at a 60.0° angle from the central maximum. What is the wavelength of this new light? a. 421nm b. 468 nm c. 445 nm d. 398 nm e. 492 nm
