Sexual Reproduction Flashcards
What is sexual reproduction?
Sexual reproduction involves the union of two sex cells or gametes
What are gametes?
Gametes are haploid cells capable of fusion
What type of cell division is involves in sexual reproduction?
Meiosis
Why is meiosis essential for sexual reproduction?
As meiosis is required to halve the chromosome number in the formation of gametes
Describe how sexual reproduction works (general)
2
Meiosis forms a gamete (haploid)
Two gametes, one from each parents, fuse to form a diploid cell called a zygote
What is different about the offspring of sexual reproduction compares to asexual reproduction?
The offspring produced as a result of sexual reproduction show variations
Why do the offspring of sexual reproduction show variations?
Due to the mixing of genes from two parents
Why is sexual reproduction said to be more advantageous to a species than asexual reproduction?
(2)
As the offspring of sexual reproduction show variations
And as variations are the basis for evolution, sexual reproduction is said to be more advantageous
Why are variations the said to be the basis for?
Evolution
