Parent cell: Ff-wW-aa-EE and LL-bb-TT / Daughter cell #1: FF-ww-aa-EE amd LL-bb-TT / Daughter cell #2: ff-WW-aa-EE and LL-bb-TT Describe the similarities and/or differences between the alleles present in the parent compared to daughter cells #1. Describe the similarities and/or differences between the alleles present in daughter cell #1 compared to daughter cell #2. Explain the mechanism for why the alleles compare in this way. Use appropriate vocabulary in your explanation. Solution Similarities and/or differences between the alleles present in the parent compared to daughter cells #1. Similarities: Gene combinations aa-EE and LL-bb-TT are common in both. The phenotypes represented by these allele combinations will be same in both parent and daughter1. Differences: Parent has Ff heterozygous genotype whereas daughter1 has homozygous dominant FF allele combination. The trait expressed by F gene will be expressed in the phenotype of both of them due to F dominant gene in both alleles. Parent has wW genotype whereas daughter1 has ww genotype. Hence trait represented by W will be expressed phenotypically only in parent due to dominant W and will not be expressed in daughter as there is no dominant W. In daughter1 only recessive phenotype will be visible. Similarities and/or differences between the alleles present in the parent compared to daughter cells #2. Again the Gene combinations aa-EE and LL-bb-TT are common in both. The phenotypes represented by these allele combinations will be same in both parent and daughter1. Differences: Daughter2 has recessive homozygous ff and dominant homozygous WW. So ff genotype will show recessive phenotypic trait and WW will exhibit dominant phenotypic trait. Whereas Parent has Ff and wW, both heterozygous but both will also express dominant trait in phenotype. The mechanism: There are two parent cells but both daughter cells are showing variation in Ff-wW-aa-EE combination only. Another parent cell having LL-bb-TT is shown same in each daughter. This may be because the later cell is not undergoing any linkage or crossover and hence not participating in genetic recombination. Thats why it is passing on as it is in the offsprings. Also, the later part of the genotype aa-EE is just passing on same to its daughters in first parent cell. It may be due to the reason that the crossing over is happening only in upper part of the chromosome and later part is left intact as it is.And is passing on to the daughters just the same. It can also be due to genetic isolation, genetic drift or mutaion that second parent cell is not undergoing any recombination and is left with its original genotypic combination everywhere..

Solution
Similarities and/or differences between the alleles present in the parent compared to daughter
cells #1.
Similarities:
Gene combinations aa-EE and LL-bb-TT are common in both. The phenotypes represented by
these allele combinations will be same in both parent and daughter1.
Differences:
Parent has Ff heterozygous genotype whereas daughter1 has homozygous dominant FF allele
combination. The trait expressed by F gene will be expressed in the phenotype of both of them
due to F dominant gene in both alleles.
Parent has wW genotype whereas daughter1 has ww genotype. Hence trait represented by W will
be expressed phenotypically only in parent due to dominant W and will not be expressed in
daughter as there is no dominant W. In daughter1 only recessive phenotype will be visible.
Similarities and/or differences between the alleles present in the parent compared to daughter
cells #2.
Again the Gene combinations aa-EE and LL-bb-TT are common in both. The phenotypes
represented by these allele combinations will be same in both parent and daughter1.
Differences:
Daughter2 has recessive homozygous ff and dominant homozygous WW. So ff genotype will
show recessive phenotypic trait and WW will exhibit dominant phenotypic trait.
Whereas Parent has Ff and wW, both heterozygous but both will also express dominant trait in
phenotype.
The mechanism:
There are two parent cells but both daughter cells are showing variation in Ff-wW-aa-EE
combination only. Another parent cell having LL-bb-TT is shown same in each daughter. This

2. may be because the later cell is not undergoing any linkage or crossover and hence not
participating in genetic recombination. Thats why it is passing on as it is in the offsprings.
Also, the later part of the genotype aa-EE is just passing on same to its daughters in first parent
cell. It may be due to the reason that the crossing over is happening only in upper part of the
chromosome and later part is left intact as it is.And is passing on to the daughters just the same.
It can also be due to genetic isolation, genetic drift or mutaion that second parent cell is not
undergoing any recombination and is left with its original genotypic combination everywhere.
