Heredity and Genetics Test (3) Review

What is the definition of Homozygous?

• When one allele is dominant and one is recessive
• When an individual has two sets of the same allele.
• when it is neither dominant or recessive

What is the definition of heterozygous?

• when an individual has two sets of the same allele

• when it is neither dominant or recessive

• when an individual has two different alleles for a gene

The genotype is the ______________.

• physical appearance
• Genetic makeup
• Alleles gained from one parent

The phenotype is the _______________.

• physical appearance of an organism
• Genetic makeup 
• Alleles acquired from a specific parent.

NGSS.HS-LS3-1

If you cross a black chicken with a white chicken, only checkered chickens would be produced.  What kind of inheritance pattern does this follow?

• incomplete Dominance
• Co-Dominance
• polygenic trait
• blocked trait

NGSS.HS-LS3-1

NGSS.HS-LS3-2

This type of inheritance pattern is a MIXTURE of both traits.

• incomplete dominance
• co-dominance
• complete dominance
• recessive pattern

A red flowered plant (RR) breeds with a White flowered plant (WW). The gene for petal color in these plants expresses incomplete dominance.  What percentage of the offspring will have pink (RW) flowers?
Hint: Use a punnett square...

• 0%
• 25%
• 50%
• 100%
