SEXUAL REPRODUCTION AND MEIOSIS Flashcards
SEXUAL REPRODUCTION PRODUCES (…)
GENETICALLY DIFFERENT CELLS
SEXUAL REPRODUCTION FANCY DENFITION IS…
SEXUAL REPRODUCTION INVOLES THE FUSION OF MALE AND FEMALE GAMETES, BECAUSE THERE ARE TWO PARENTS, THE OFFSPRING CONTAIN A MIXTURE OF THEIR PARENTS GENES
SEXXUAL REPRODUCTION IS WHERE GENETIC INFORMATION FROM TWO ORGANISMS (…° IS COMBINED TO PRODUCE (…) WHICH ARE (…) TO EITHER PARENT
A FATHER AND A MOTHER/OFFSPRING/GENETICALLY DIFFERENT
IN SEXUAL REPRODUCTION THE MOTHER AND THE FATHER PRODUCE (…)
GAMETES
WHAT ARE GAMETES
GAMETES ARE SPERM CELLS AN,D EGG CELLS
GAMETES ARE HAPLOID, THIS MEANS…
THEY HAVE HALF THE NUMBER OF CHROMOSOMES IN A NORMA CELL
EACH GAMETE CONTAINS (…) CHROMOSOMES, SO THE HAPLOID NUMBER IS (…)
23/23
AT FERTILISATION…
A MALE GAMETE FUSES WITH A FEMALE GAMETE TO FORM A ZYGOTE (FERTILISED EGGS) THE ZYGOTE ENDS UP WITH THE FULL SET OF CHROMOSOMES
THE ZYGOTE THAN DIVIDES BY MITOSIS AND DEVELOPS INTO AN (…)
EMBRYO
THE EMBRYO INHERITS FEATURES FROM BOTH PARENTS BECAUSE…
IT HAS RECIEVED A MIXTURE OF CHROMOSOMES FROM ITS MUM AND DAD
THE FERTILISATION OF GAMETES IS RANDOM, THIS PRODUCESS (…)
GENETIC VARIATION IN THE OFFSPRING
GAMETES ARE PRODUCED BY (…)
MEIOSIS
MEIOSIS IS ANOTHER TYPE OF CELL DIVISION, ITS DIFFERENT FROM MITOSIS BECAUSE (…)
IT DOESNT PRODUCE IDENTICAL CELLS, IT HAPPENS IN THE REPRODUCTIVE ORGANS (OVARIES AND TESTES)
MEIOSIS PRODUCES (…)
FOUR HAPLOID CELLS WHOSE CHROMOSOMES ARE NOT IDENTICAL
