Does combining more than one gene exacerbate the effects?
Yes
What is a polygenic risk score?

What is the process for creating gametes?
meiosis
Are somatic cells 2n or n and what does that mean?
they are 2n which is diploid which means double the chromosomes so the 23 chromosomes 46 chromatids.
Are gametes 2n or n and what does that mean?
gametes are n which is haploid which means hald the number of chromosomes so 23 chromosomes and 23 chromatids
How are chromosomes counted?
centromeres
What is a centromere?
the connecter of chromatids
What cells do gametes come from?
germ cells
Where are germ cells located?
ovaries/testes
What are the two types of gametes?
egg and sperm
What are autosomes?
chromosomes numbered 1-22
