Inference of mitosis |
|
Answer» The fraction labelled mitoses curve is widely used to study the premitotic phase of the cell cycle in proliferating cell populations. The population is here assumed to be in a steady state of exponential growth. The theoretical curve is derived in an explicit computational FORM, allowing for correlations between PHASES. This gives the likelihood function explicitly, and classical maximum likelihood METHODS of fitting the theoretical curve to experimental data can work very well. The curve may OFTEN be approximated by assuming a joint normal distribution of phase times, and computation of the curve and of the maximum likelihood estimates then becomes straightforward. The mitotic index may sometimes be used to give supplementary information about the mean mitotic time. Weak inferences about the presence of absence of negative correlations between certain phases are possible. The methods are ILLUSTRATED with three examples of experimental data. |

What are the factors oriented chromosome appearing in f1 generation after cross pollination among tall and dwarf pea plants.PLEASE ANSWER IT IMMEDIATELY GUYS. |
|
Answer» F1 generation contained all TALL plants when the two plants one with tall character and other with dwarf trait UNDERWENT cross pollination . When F1 generation underwent self pollination the trait they was unexpressed in F1 generation (dwarf) was OBSERVED in F2 progeny . So the ratio of tall plants : dwarf plant were in the ratio 3:1in the F2 progeny . The above experiment INDICTED that although both the traits of tallness and dwarf ness were INHERITED in F1 plants only the dominant (tallness ) trait was expressed. This shows that traits might be dominant or recessive and they may not show up in an individual but are passed on to the next generation . |
