Pro of sexual reproduction |
- combination of genes helps organisms evolve and adapt in a healthier way. - combination of genes assures a lesser chance of new organism to acquire disease and other defects |
|
Cons of sexual reproduction |
-no garenty, only works if gametes fuse -only females can reproduce -takes longer |

Zygote |
The diploid cell formed by an egg and sperm |
|
Diploid |
A cell containing two complete sets of chromosomes, one from each parent. |
|
Haploid |
A cell containing a single set of unpaired chromosomes |
|
Asexual |
Production of genetically identical offspring from one parent |
|
Pro sexual |
Genetic diversity |
|
Pro asexual |
Fast time to reproduce not much energy |
|
Asexual |
Produces clones |
|
Con sexual |
Takes longer and more energy and needs to find a mate |
|
Con asexual |
Can all be wiped out at once by disease or environmental change |
|
Meiosis |
Cell division that results in 4 daughter cells with half the chromosomes of each parent cell. |
|
Mitosis |
Cell division resulting in 2 daughter cells each with the Sam number of chromosomes as the parents |
|
Gametes |
Egg or sperm |
|
Genetic Variation |
Produced by recombination of chromosomes during sexual reproduction. The crossing over that occurs during meiosis can result in the production of new alleles or new combinations of alleles |
