Sexual and Asexual Reproduction Flashcards
What are gametes?
Sex cells
What are the gametes in animals?
Sperm and Egg
What are the gametes in plants?
Pollen and egg
What does sexual reproduction involve?
The fusion of the male and female gametes (fertilisation)
How many parents are involved in sexual reproduction?
Two parents
The production of gametes involves [blank]
fill in the blank
The production of gametes involves meiosis
Asexual reproduction involves the fusion of gametes
TRUE or FALSE
FALSE
There is no mixing of genetic material in asexual reproduction
TRUE or FALSE
TRUE
In asexual reproduction are the offspring genetically identical or non-identical?
Genetically identical
What process is the only one involved in asexual reproduction?
Mitosis
Describe the process of meiosis
1) In a cell in the reproductive organs,copies of the genetic material are made
2) The cell then divides twice to form four haploid gamete cells
3) Each of the gametes are genetically different from eachother
Why is it bad that asexual reproduction produces no variation in offspring?
If there is a disease or a change in the environment it will affect the entire population
How is the normal number of chromosomes restored ?
The male and female gamtetes fuse in fetilisation to form a diploid cell
This cell then divides by mitosis, as the number of cells increases an emmbryo is formed
As the embryo develops cells differentiate
