What is a Karyotype?
a visual representation of an individuals entire genome organised into homologous pairs
What does Meiosis do?
produces haploid gametes, sperm and an egg, from diploid cells for sexual reproduction
What is crossing over?
a pair of chromosomes swap pieces of DNA during meiosis, which creates new combinations of genes on each chromosome
What is Independent Assortment?
when chromosome line up and seperate randomly during meiosis, which makes each gamete have a random mix of chromosomes from each parent
What is a Dominant Allele?
it will always be expressed even if the individual only has one copy
What is a Recessive Allele?
will only be expressed if the individual has two copies of that allele
What is codominance? (+example)
when both alleles from the genotype are fully expressed in the phenotype eg. both colours are present
What is Incomplete Dominance? (+example)
when neither genotype is fully expressed in the phenotype eg. a blend of both colours
