Meiosis II is a _________.
Reductionnal division
Similar to Meiosis I
Equational division
Both (a) and (c)
Meiosis differs from mitosis in that
first division is reductional and second division is equational
first division is equational and second division is reductional
both divisions are reductional
both divisions are equational
Plant material suited studying meiosis is
Cork
Root tip
Anther
Meristem
Segregation of Mendelian factors occurs during
diplotene
anaphase - I
zygotene/ pachytene
anaphase- II
As compared to mitosis in meiosis
Two replication cycle of DNA is followed by two divisions
Four diploid cells are formed
Every chromosome behaves independently
Genetic variabilities are introduced in daughter cells
During which stage of prophase I the crossing over takes place?
leptotene
pachytene
zygotene
Which of the following molecules consists of two polynucleotide chains (strands).?
RNA
DNA
Both a and B
None
When number of chromosomes is already reduced to half in the first reductional division of meiosis. What is the necessity of second mitotic division?
the division is required for the formation of four gametes
division ensuress equal distribution of haploid chromosomes
division ensures equal distribution of genes on chromosomes
division is required for segregation of replicated, chromosomes
The number of chromosomes becomes half in
anaphase I
anaphase II
telophase I
telophase II
Meiosis occurs in
Liver
Kidney
Gonad
Brain
