sexual and asexual reproduction Flashcards
what does asexual reproduction involve
1 parent, no fusion of gameates, no mixing of genetic information, mitosis
what does sexual reproduction involve
fusion of gameates, mix of genetic information, variation in off spring
what are some examples of gameates
sperm + egg
pollen + egg
what is meiosis
fusion of gameates
what happens when a cell divides by meiosis
copies of genetic info are made
4 gameates with a one set of chromosomes each
all gameates genetically different from eachother
how do strawberries reproduce asexually
runners that reach to the ground then grow a new plant
how to daffodils reproduce asexually
small bulbs that grow into new plants
how do fungi reproduce asexually
spores
how do malaria parasites produce sexually and asexually
sexually in mosquitoes but asexually in humans
what are some advantages of sexual reproduction
1) variation in offspring
2) easily adaptable to environment
3) allows selective breeding
what are some advantages of asexual reproduction
1) only 1 parent needed
2) time and energy efficient
3) faster
4) many identical off spring to make most of good conditions
explain meiosis
1) starts with a diploid cell
2) each chromosome replicates
3) chromosomes move to opposite sides of cell
4) cell divides
5) copies if chromosomes separate to opposite sides of cells and the cells split again
6) you’re left with 4 haploid cells with 1/2 the chromosomes that the parent has
what’s a diploid cell
a cell with 2 pairs of chromosomes
what’s a haploid cell
a cell with half the number of chromosomes that the parent has
