T/F Sexual reproduction leads to the creation of a offspring that is not identical to the parent
TRUE
T/F Une cellule reproductif sexuee est appellé zygote
Faux: Gamete
When the gamete cells of both parents combine, this is called ______
Fecondation
T/F When fecondation happens, a zygote is formed which is the first somatic cell for the new organism
TRUE
T/F Organisms within a species are different through the number of chromosomes.
FAUX
T/F In every chromosome homologue, both chromatides DON’T have the same dimensions and form
F: Do
Explain chromosomes homologues breifly
2 pairs of chromosomes that are the same (one from father and mother)
A table or a list of the chromosomes of a indivdual or a species is called ________
Caryotype
T/F The parent organisms always have “2n” chromosomes but the offspring has only “n” chromosomes
F: The offspring also has 2n chromosomes (meiose n+n=2n)
Une spermazoide et une ovule sont des exemples de chromosomes… 2n or n (choose one)
These two are examples of “n” chromosomes
Only the gametes ______ can merge to become zygote diploide
haploide
T/F It’s only in {mitosis} that the number of chromosomes are able to divide (switch the word)
Meiose
In phase ____ of meiose the anaphase consists of the centromere being seperated
Phase 2
Which phase of meiosis is more “comparable” to mitosis
Phase 2
The objective of phase 1 of meiosis is to divide _______
Cellules homlogues
T/F Phase 2 of meiose ends with {4} “n” cells. (switch number if false)
TRUE
T/F For females the process of meiose ends with the creation of a total of 4 Ovules haploide
F: Only one Ovule haploide is created.
T/F: Le processus par lequel chaque gamète renferme des chromosomes homologues de chaque paire est appelé méiose.
F: Le processus par lequel chaque gamète ne renferme qu’un seul chromosome de chaque paire est appelé méiose.
Definition du nombre haploide
C’est quoi la nombre haploide dans les humains? La nombre des chromosomes dans un cellule gamète d’un spécies 23
