About this Exam

Prepare with the Bac SVT Practice Questions - Baccalaureat General - Specialite Sciences de la Vie et de la Terre (SVT) Exam practice quiz. This question bank includes 100 questions covering because, sub-theme, terminale, mainly, and muscle. Use it to review important concepts, identify knowledge gaps, and build confidence for the related exam, course, or assessment.

Sample Questions

Question 1
In the Terminale SVT theme 'La Terre, la vie et l'organisation du vivant', meiosis produces gametes that are:
diploid and genetically identical to the parent cell
diploid with twice the chromosome number
haploid and genetically original
haploid but always identical to one another
Question 2
The 'brassage intrachromosomique' (intrachromosomal shuffling) studied in Terminale SVT occurs by which mechanism?
random alignment of homologous chromosomes at metaphase I
fertilisation between two random gametes
separation of sister chromatids during anaphase II
crossing-over (enjambement) between homologous chromatids during prophase I
Question 3
Interchromosomal shuffling (brassage interchromosomique) is the consequence of which event during meiosis?
the random distribution of paternal and maternal homologues at anaphase I
the exchange of chromatid segments at chiasmas
DNA replication during interphase
the fusion of two haploid nuclei
Question 4
Considering only interchromosomal shuffling, how many genetically different gametes can a human (2n = 46) theoretically produce?
2^23 (about 8.4 million)
2^46
23
46
Question 5
Fertilisation contributes to genetic diversity primarily because it:
doubles the number of crossing-overs
unites two haploid genomes of independent origin at random
creates new alleles by mutation
halves the chromosome number
