Inheritance, Variation, and evolution Flashcards
What are the pro’s of sexual reproduction?
Allows for mutations between generations which allows for characteristics to develop and improve
Pro’s of asexual production?
Creates genetically identical daughter cells
what is meisois?
creation of gametes
Involves two divisions
And non identical to parent cells
What is sexual reproduction?
Involves the process of creating gametes by meiosis
A gamete fuses with another to create a zygote
The genetic information is mixed resulting in a unique zygote
What are gametes?
sex cells that are haploids
What occurs before meiosis
Interphase- the duplicating of organelles + Dna
Why is meiosis important to sexual reproduction?
Increases genetic variation
Ensures the zygote is a diploid
Describe the circumstances in which malarial parasites reproduce sexually and asexually
Reproduces sexually while in the mosquito
Reproduces asexually while in the body
Circumstances is which mushrooms reproduce sexually and asexually?
Sexually when they need to create variation
Asexually by releasing spores
Describe the circumstances in which plants reproduce sexually and asexually?
Sexually to produce seeds
Asexual by runners or blub division
What is DNA
di-oxyribonuleic acid
A double stranded polymer of nucleotides in a double helix
Def of genome
The entire genetic material of an organism
why should we understand the genome?
Searches for genes linked too different types of diseases
Understanding inherited disorders
Tracing disease from human migration
