Lab #18 Meiosis Done

What genetic process will students observe that is produced by sexual reproduction?

• Genetic mutation

• Genetic variation

• Genetic drift

• Genetic engineering

This is a gene that you get from your mom or dad.

• Phenotype

• Genotype

• Allele

• Recessive

This process involves homologous chromatids exchanging genetic material to increase genetic diversity.

• crossing over

• random fertilization

• independent assortment

• gene flow

Genetic differences between organisms of the same species

• Variation
• Adaptation
• Behavior
• Environment

What is genetic variation?

• The lack of differences among individuals in a population

• The uniformity of traits in a species

• Differences in the genetic makeup among individuals within a population

• The study of heredity

What is an allele?

• version of a gene
• trait determined by many genes
• Dna sequence that determines a trait

Fitness is an organism's relative ability to _

• carry more weight

• move faster

• be more attractive

• survive

Why is genetic diversity important?

• It slows down the growth rate of a population

• It makes all individuals in a population the same

• It prevents adaptations from occurring

• It allows for natural selection to occur

• INCREASES GENETIC VARIATION

• TAKES PLACE IN PROPHASE I

• CROSSING OVER

• ALL ARE TRUE

What phase is  shown in the picture?

• anaphase 1
• anaphase 2
• metaphase 1
• telophase 1
