Meosis Presentation Transcript

Slide 1 - Meiosis Cell division – ‘reduction division’ Production of sex cells – gametes Meiosis errors
Slide 2 - Why do we need meiosis? Meiosis is necessary to halve the number of chromosomes going into the sex cells Why halve the chromosomes in gametes? At fertilisation the male and female sex cells will provide ½ of the chromosomes each – so the offspring has genes from both parents
Slide 3 - ppt slide no 3 content not found
Slide 4 - Meiosis Parent cell – chromosome pair Chromosomes copied 1st division - pairs split 2nd division – produces 4 gamete cells with ½ the original no. of chromosomes
Slide 5 - Meiosis – mouse testes Parent cell 4 gametes 1st division 2nd division
Slide 6 - Meiosis – division error Chromosome pair
Slide 7 - Meiosis error - fertilisation Should the gamete with the chromosome pair be fertilised then the offspring will not be ‘normal’. In humans this often occurs with the 21st pair – producing a child with Downs Syndrome
Slide 8 - 21 trisomy – Downs Syndrome Can you see the extra 21st chromosome? Is this person male or female?
