EOY-REVISION

Which stage of meiosis is shown in this diagram?

• anaphase I

• anaphase II

• metaphase I

• prophase I

Which of the following correctly describes the process shown?

• segregation of sister chromatids during anaphase II

• alignment of homologous chromosomes during metaphase I

• segregation of homologous chromosomes during anaphase I

• crossing over in which genes (alleles) are exchanged during prophase I

Which of the following describes meiosis correctly? choose two options

• Cell division that produces four haploid gametes

• Cell division that produces four diploid gametes

• Cell division that reduces the number of chromosomes into half

• Cell division that keeps the same number of chromosomes

What phase of meiosis is shown in this diagram?

• Metaphase II

• Telophase I

• Telophase II

• Anaphase I

This diagram displays------------------ as -----------------------

• Prophase II as nuclear envelop starts to disappear

• Prophase I as crossing over starts

• Anaphase II as sister chromatids pulled away

• Metaphase II as homologous chromosomes line up at the middle

Which of the following are correct about a pair of homologous chromosomes?

I. Carry genes that control the same traits

II. Have the same centromere position

III. Have the same length

• I and II

• II and III

• II and III

• I , II and III

Diagram shows a diploid cell. How many chromosomes in its haploid cell?
