Genetics

When two alleles are the same

• Heterozygous

• Homozygous

When two alleles are different

• Homozygous

• Heterozygous

Alternate versions of a gene, one comes from mom and the other from dad

• Homozygous

• alleles

• Dominant

• Recessive

The observable, physical trait

• Allele

• Homozygous

• Genotype

• Phenotype

Phenotypes are made by this, the genetic makeup

• Heterozygous

• allele

• Genotype

• Mutation

A square that is used to predict the offspring when 1 trait is crossed

• Meiosis

• Monohybrid punnett square

• Homologous chromosomes

Chromosomes that are similar in size, shape and genetic content. One from mom and one from dad.

• Chromosomes

• Meiosis

• Crossing over

• Homologous chromosomes

The exchange of genetic information that increases genetic variation, occurs during meiosis

• DNA replication

• Protein Synthesis

• Crossing over

• Punnett square

True or False. Recombination of homologous chromosomes decreases variation.

• True

• False

The process that makes 4 genetically different cells each with half the number of chromosomes.

• Mitosis

• Meiosis
