A 2n = 3 cell can be:
a. Monosomic
b. Autopolyploid
c. Allopolyploid
d. a or b
e. a or c
Answer:
(a)Monosomic .As here the ploidy is 2n=3, the rule that works here is (2n-1), a case where one chromosome from the set has been deleted . Both autopolyploidy and allopolyploidy are examples where there are a more set of chromosomes, so it would always be even.
Give a thumbs up if you like the answer. Thank you

The fusion of non-reduced gametes will produce a. somatic doubling b. allopolyploid c. autopolyploid d. haploidy e. Trisomies

. . Colchicine can be used to alter the chromosome content of a cell by disrupting chromosome disjunction and cell division (an exposed cell would enter mitosis but fail to divide). After treatment with colchicine, the altered chromosome content would make the cell autopolyploid triploid aneuploid allopolyploid
A tetraploid cell (4n = 8): a. could be an autotetraploid from two parents, each 2n = 4 b. could be an allotetraploid from two parents, each 2n = 2 c. could be an allotetraploid from two parents, 1n = 2, 3n = 6 d. A or B e. A or C
Which cell can transfer the most DNA? A) F+ cell B) R cell C) Hfr cell D) B cell E) F- cell
For a cell that is right after DNA replication, where 2n=6 a. Is this cell haploid, diploid, or tetraploid? b. How many molecules of DNA are there? c. Are chromosomes single stranded or double stranded? d. How many chromosomes are there e. How many homologous pairs are there f. How many unique chromosomes are there g. How many sister chromatid pairs are there Thank you very much!
41. (6 pts) You are breeding two polyploid species of wheat. You
cross the two different
species (parent 1 x parent 2) and obtain F1 hybrids. The following
meiotic pairing was
observed in the F1 hybrid:
F1 hybrid = 12 bivalents + 12 univalents
(A) How many chromosomes are there in a non-dividing somatic cell
of an F1 plant (i.e. what
is the organisms ploidy)?
(B) How many chromosomes are there in a non-dividing somatic
cell of each parent (i.e....
chromosomal sets in an allopolyploid are a. identical to each other b. vary slightly from eachother c. are identical to the dominant parental type d. are obtained from parents of the same species.
