Adiploid cell contains three pairs of homologous chromosomes designated c1 and c2, m1 and m2, and s1 and s2; no crossing over occurs. what possible combinations of chromosomes will be present ina) daughter cells following mitosis? c1/c2 , m1/m2 , s1/s2b) the first meiotic metaphase? c1/c2 , m1/m2 , s1/s2c) haploid cells following both divisions of meiosis?

Your question is in three parts, you asked for a help on the THIRD part, it is provided below.

The combinations of chromosomes present in

A) daughter cells following mitosis will be C1/C2 , M1/M2 , S1/S2

B) the first meiotic metaphase will be C1/C2 , M1/M2 , S1/S2

C) haploid cells following both divisions of meiosis will be C1, M1, S1 & C2, M2, S2

Explanation:

A diploid cell has two sets of chromosomes called homologous chromosomes and represented as 2n.

For part A: The daughter cells after mitosis has SAME chromosome number and content as parent diploid cell C1/C2 , M1/M2 , S1/S2 as homologues because NO exchange of material (crossing over) occur during mitotic division

For part B: During the 1st meiotic metaphase, chromosomes of the diploid cell are just assembled, they are YET to be separated, thus its chromosome is SIMILAR to diploid cell

For part C: haploid cells following both divisions of meiosis will be C1, M1, S1 & C2, M2, S2. This is because during meiosis, the number of chromosomes in diploid cell is HALVED (2n becomes n). Thus, haploid cells carries ONLY one set of chromosomes in diploid cell.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."
