Solved in 2 steps
- Discuss the following sets of terms: a) trisomy and triploidy, b) aneuploidy and polyploidy.Discuss the following sets of terms: a. trisomy and triploidy b. aneuploidy and polyploidyDefine these pairs of terms, and distinguish between them.aneuploidy/euploidymonosomy/trisomyPatau syndrome/Edwards syndromeautopolyploidy/allopolyploidyautotetraploid/amphidiploidparacentric inversion/pericentric inversion
- Consider the true diploid plant cell (2n=4) below. The paternally derived blue chromosomesare of two types, metacentric and acrocentric. These chromosomes contain the same gene pattern andstructural features as the maternally derived purple chromosomes. Consider two genes A and B whichare found on the metacentric and acrocentric chromosome pairs, respectively. Assume the father passedon A and B alleles, and the mother passed on a and b alleles. a. Show the possible loci of these genes (specify alleles) on the image. Label both sister chromatids in each chromosome. (Note: Sister chromatids are products of replication.)b. Draw the four possible gametes formed after meiosis assuming there was no crossing over. Label the gene loci.What causes Allopolyploidy?what are allopolyploids.?
- define allopolyploidsAssume that a diploid cell (2N=8) contains 4 pairs of chromosomes (3 pairs of autosomes and 1 pair of sex chromosomes) designated as 1m, 1p, 2m, 2p, 3m, 3p, Xm, and Xp where "m" stands for maternal origin and "p" stands for paternal origin.

Letters that are similar represent one gene found in a pair of homologous chromosomes. Another letter represents another gene found in another pair of chromosomes. Draw how these different pairs of chromosomes behave during meiosis. Show the complete phases of meiosis for each of the following: (a) Cc (b)BbCC (c)DdEe (d) AAbbCc (e) AaBbCcDd
