Parental chromatids are chromatids that have a combination of alleles identical to the parents and Recombinant chromatids are chromatids that have a mix of alleles from both parents.

What is the difference between sister and non sister chromatids?
Sister chromatids are those replicated from the same chromosome whereas non-sister chromatids may be found in meiosis (particularly metaphase II) where paternal and maternal chromatids line up and eventually separate at the metaphase plate.
Distinguish between parental and recombinant phenotypes?
Parental Phenotypes are when the offspring of two parents look like one of the two parents. for example, if a green wrinkled pea is crossed with a heterozygous yellow round pea the offspring are 1/4 yellow round, 1/4 green wrinkled, 1/4 yellow wrinkled, and 1/4 green round. the yellow round and green wrinkled look like the parents so they have parental phenotypes, whereas the yellow wrinkled and the green round have combinations of the parental phenotypes thus they have recombinant phenotypes.
What is the difference between anaphase and telophase?
anaphase is when the centrosomes start to pull the sister chromatids apart. Telephase is when the cell actually divides in 2
Why do you use non-sister chromatids to demonstrate crossing over?
Crossing over occurs between homologous chromosomes, which are not identical, as one member of each pair of homologous chromosomes comes from the mother, and one member comes from the father. Sister chromatids are identical and crossing over would have no effect.
What is the site of crossing over between two non-sister chromatids?
Chiasma - The microscopically visible site where crossing over has occurred between chromatids of homologous chromosomes during prophase I of meiosis.
Difference between paracentric and pericentric inversion?
The position of the centromere in the recombinant products.
What is the difference between mitosis 2 and meiosis?
During mitosis, sister chromatids are separated.
Difference between sister chromatids and homologous chromosomes?
Homologous chromosomes are individual chromosomes inherited from each parent. Sister chromatids are the result of DNA replication, and the are identical.
What is the difference between kinetochore and centromere?
kinetochore is the site of attachment of spindlefibres. centromere is the center of attachment of the chromatids
What is the difference between sister and non sister chromatids?
Sister chromatids are those replicated from the same chromosome whereas non-sister chromatids may be found in meiosis (particularly metaphase II) where paternal and maternal chromatids line up and eventually separate at the metaphase plate.

What is the point of attachment between two chromatids?
The point of attatchment between two chromatids is called the centromere. When two chromatids are connected, it is called a chromosome which is essential in DNA replication, or, mitosis.
What is the difference between anaphase and telophase?
anaphase is when the centrosomes start to pull the sister chromatids apart. Telephase is when the cell actually divides in 2
Chiasmata form between.?
Sister chromatids
What is the different between recombinant DNA and non-recombinant DNA?
Recombinant- is the DNA fragment of interest Nonrecombinant- the undesired foreign DNA
What's the difference between meiosis ii and mitosis?
In both cases chromosomes line up and sister chromatids are separated by the action of the spindle fibers. The daughter cells are genetically identical to one another
Why do you use non-sister chromatids to demonstrate crossing over?
Crossing over occurs between homologous chromosomes, which are not identical, as one member of each pair of homologous chromosomes comes from the mother, and one member comes from the father. Sister chromatids are identical and crossing over would have no effect.
