Inheritance Flashcards
What is sexual reproduction
Sexual reproduction is a biological process that involves the fusion of two gametes to produce offspring
What type of cell division is involved in asexual reproduction
Mitosis is the type of cell division involved in asexual reproduction. It produces genetically identical daughter cells, resulting in clones of the parent organism.
What type of cell division is involved in sexual reproduction
Meiosis is the type of cell division involved in sexual reproduction. It reduces the chromosome number in gametes
What is meiosis
A form of cell divison that produces gametes which are non-identical cells with half the usual chromosome number
What are the male and female sex chromosomes in humans
XX, XY
What are the male and female sex chromosomes in flowering plants
In flowering plants, the male gametes are called pollen grains, and the female gametes are called ovules.
What is material in cells called
DNA
What is the structure of DNA
A double-helix structure
What is a gene
A section of DNA that codes for a specific sequence of amino acids which undergo polymerisation to form a protein. Genes determine the inherited traits of an organism.
What are alleles
Alleles are different versions of the same gene. They can influence the expression of a trait, leading to variation within a species.
