Crossing over occurs during Prophase 1 of meiosis. When homologues chromosomes are lined together once the chromosomes pair together breaks will occur in non-sister chromatids that are identical sites. The non-sister chromatids exchange broken segments which are then sealed together by specific enzymes. Crossing over breaks up all combinations of alleles and puts new ones together in pairs of homologous chromosomes (tetrad) this process increases genetic variability. ....:D:D:D:D
The FitnessGram™ Pacer Test is a multistage aerobic capacity test that progressively gets more difficult as it continues. The 20 meter pacer test will begin in 30 seconds. Line up at the start. The running speed starts slowly, but gets faster each minute after you hear this signal. [beep] A single lap should be completed each time you hear this sound. [ding] Remember to run in a straight line, and run as long as possible. The second time you fail to complete a lap before the sound, your test is over. The test will begin on the word start. On your mark, get ready, start.
Love these straight forward videos. No intro, no sellout, no bullshit. Just education
who came to watch this because of Kognity
You explain it better than kognity
Would've been better if it was Morgan Freeman.
Best voice ever.
Muy buen video

Crossing over
thank you !!
where the kognity people at hello kognity people
There's a little mistake the head first splits off after they crossed each other👍
hehe :)) familiar from somewhere :)) :P
That is one old comment!
Me gusta porque se ve un crosing over entre cromátidas alejadas de cromosomas homólogos ,
variabilidade genética.....
