Answer:
Explanation:
At the ending of pro phase or late prophase, the mitotic spindle begins to capture and organize the chromosomes.
* The chromosomes have finished condensing and are now very compact.
* The nuclear envelope is broken down and the chromosomes are released.
* The mitotic spindle grows more, and some of the microtubules start to “capture” chromosomes.
Answer:
A white mouse is purely recessive, and will produce black offspring if the other mouse contributes a black gene.
Explanation:
If Bb then the offspring will be 50% Bb and 50% bb. This is called a test cross, where we use a recessive to determine the genotype of a dominant phenotype.
gene flow or migration between two populations will help maintain similarities between the species, therefore preventing (or slowing down) the process of speciation. and when the environment changes rapidly, this can cause an overall decrease in population size because of a failure to adapt adequately to environmental changes. i hope this helped <3
