Question 1: Describe and explain how the following ideas supported the 'Discrete Particle of Inheritance.'

a) Principle of Segregation

b) Principle of Independent Assortment

c) Dominant and recessive alleles

d) Statistical analysis and probability

The discrete particle of inheritance model impersonates sexual reproduction through generations of offspring. By manifesting gametes and consolidating them in fertilization a gauche model of what could happen will be produced. The model congregated is not transcendent since mutation is not accounted for during simulation.

The principle of segregation, by Mendel, justifies the discrete particle of inheritance model because it inaugurates the separation of paternal and maternal genes for traits of the offspring. Some genes were dominant and some were recessive. The genes from the predecessors would associate to form traits.

Example:

R=round(Dominant) r=wrinkled(Recessive)

If we combine a RR with a rr 100% of the offspring would have the genotype of Rr and would be round.

However, if a Rr and a Rr are combined then: 25% would be RR, 25% rr, and 50% Rr.

The principle of independent assortment also reinforces the discrete particle of inheritance model by presentation of how the separation of male and female genes for different traits are interjected in producing traits for the offspring. This explained how some peas were wrinkled and green and some were round and yellow.

Example:

R=round(Dominant) r=wrinkled(Recessive) Y=yellow(Dominant) y=green(recessive)

If a RRYY is combined with a rryy then 100% of the offspring will have the genotype of RrYy. But if a RrYy is combined with another RrYy then: 25% RrYy, 13% RRYy, 13% RrYY, 13% Rryy, 13% rrYy, 6% RRYY, 6% RRyy, 6% rryy and 6% rrYY.

Dominant and recessive alleles supports the discrete particle of inheritance model because it explains how a trait can disappear...
