Unit 7 Exam 1 (Study Session)

Different variations of genes are...

• Genomes

• Alleles

• Chromosomes

• Genes

The traits of an organism are passed to its offspring on small coded strands of DNA material called

• meiosis
• recessive traits
• genes
• heredity

If a person has 2 different alleles for a gene, their alleles are ​considered ​ (a)   , but if they have 2 of the same alleles, their alleles are ​ (b)   .

• heterozygous
• homozygous
• different
• similar

This type of allele is expressed whether there are one or two copies present.

• dominant

• recessive

• homozygous

• heterozygous

What tool can we use to predict what traits offspring will have?

• Punnett Square
• Wardlaw Rectangle
• Mendel Circle
• Preston Square

Expressed only if NO dominant version is present

• homozygous
• heterozgyous
• allele
• recessive

Match the following vocabulary words with their definitions

• The specific genetic make up or "code" for an individual.

• Trait

• An organism's characteristics.

• Heredity

• The process in which characteristics are passed down from parents to offspring.

• Genotype

• Phenotype

• The total physical appearance for an individual.

Answer explanation

Remember:

The traits are PASSED down through generations!

That is heredity!
