Chromosome Mutations in Meiosis
Just as mutations can occur at the level of the gene, mutations can also
occur at the level of the chromosome
Because chromosomes are made up of thousands of genes, these mutations
can have a very large impact on th
The early development of an organism is called embryonic development.
In humans, this takes place during the first two months after fertilization.
After fertilization, the zygote undergoes mitosis
By the end of week 1 it form
Sexual Reproduction - KEY
Sexual reproduction involves bringing the non-identical gametes produced by meiosis (a sperm and an egg)
together to form a new organism requires 2 parents
Has 3 stages:
o Mating = process by which gametes arrive in the sa
