Meiosis and Heredity Practice Quiz

The end product of meiosis is:

• haploid sex cells

• diploid sex cells

• haploid somatic cells

• diploid somatic cells

The letters on a Punnett square represent alleles. The alleles on the outside belong to the ____________ and the alleles on the inside belong to __________ ________________?

• parents; possible offspring

• offspring; possible parents

• parents; haploid cells

• gametes; sex cells

Independent assortment and crossing over are two processes in meiosis. Why are they important?

• They create identical gametes, providing organisms the same chance of survivial

• They increase variation, providing organisms a means to change/evolve

• They decrease variation, always providing organisms the best traits

• Meiosis actually provides a lot of complications for living things, it is not beneficial

An allele is a ...

• list of always 2 opposite components (like Aa or Tt, but never AA or TT)

• general description for a gene (like hair color in general)

• specific version of a phenotype (like brown or red when speaking of hair color)

• dominant trait, always dominant
