Which of the following statements was not a contributing factor in the generation of Mendels first three postulates

All of offspring of the first filial generation demonstrated the same trait

model organism

An organism selected for intensive scientific study based on features that make it easy to work with (e.g., body size, life span), in the hope that findings will apply to other species.

The event referred to as disjunction occurs during

Anaphase

Chromosome number reduction takes place in

Anaphase II

Mendel specific contributions in genetics published in 1866 whet largely unnoticed until the discovery of_______

False

During preprophase the nucleus moves to the center of the cell

False

During telophase two of mitosis sister chromatids remain together despite the separation of homologous chromosomes

False

M phase is an important cellular stage process when homologous chromosome is prepare to pair

The investigative approach of genetics attributed to Gregor Mendel is

Transmission genetics

A Chromatid is one of the two identical copies of DNA make up a chromosome

True

During telophase the cell continues to stretch and lengthen while a new nuclear envelope forms around each set of separated sister chromosomes

True

G0 phase is not a part of interphase

True

Interphase is the process during which a cell prepares for division

True

Meiosis is the phase of the cell cycle where two identical daughter cells are created

True

Mitosis is the process by which chromosome are duplicated within cells

True

Prophase is a stage of the mitosis in which the Chromatin condensed into a highly ordered structure called a chromosome

True

The key players controlling cell cycle progression are cyclin/ CDK protein complexesn

True
