What changes occur in the genes of sex cell

Biology
1 answer:
Flauer [41]3 years ago

During Telophase 2, a nuclear envelope forms around each set of new chromosomes. In this stage, cytokinesis occurs, which is responsible for producing four daughter cells each with a haploid set of chromosomes. During the crossing-over phase some chromosomes are observed to have segments that have recombined with the original parent chromosomes.   
<span>
When the phase is over, the two cells are now finally separated and their nuclear membranes are fully formed causing the meiosis cell division to be completed.</span>

True or false? A mating between a tetraploid individual and a diploid individual produces biologically fit offspring.
Katyanochek1 [597]

A cross between a diploid individual and a tetraploid individual produces triploid offspring.  There are many species of plants that are triploid, but those come from crosses between two triploid individuals. In those cases, the chromosomes from one parent match up with the chromosomes from the other parent just fine. The same is not true with a cross of a tetraploid and a diploid.  In that case, one third of the chromosomes are unmatch, causing many offspring to die, to be sterile, or to be generally unfit.  Long story short, the answer you seek is False.

Why is the microscope important to the study of microlife?
Sophie [7]
Wait this is highschool biology?! 
Woah... thought it would be harder....


Anyways, see "micro" means really small, so small that your bare eyesight can't take it (or see it, I don't care). A microscope was meant to see things that our eyes can't. Since humans cant see microlife we use a microscope. 

Mind Blown...

What two types of evolutionary evidence, taken together, provide strong evidence for when extinct species most likely diverged f
Black_prince [1.1K]

Homologous and analogous structures are two types of evolutionary evidence, taken together, provide strong evidence for when extinct species most likely diverged from common ancestors, relative to other events happening on Earth.

Several types of evidence support the theory of evolution: If two or more species share a unique physical feature, such as a complex bone structure or body plan, they can all inherit this property from the common ancestor. Physical traits shared through evolutionary history (common ancestor) they say they are homologous. Not all physical properties that look similar are signs of common ancestry. Some physical similarities instead are analogous: they evolved independently in different organisms because organisms lived in similar environments or experienced similar selective pressures.
