Unit 7: Day 3

What type of inheritance do two alleles have if their traits blend together? 

• Incomplete Dominance
• Co-Dominance
• Mendelian Inheritance
• Homozygous Inheritance

a trait that is masked, wont show up first

• dominant trait
• genotype
• recessive trait
• hair color

the characteristics of a trait that you can see

• phenotype
• genotype
• dominant
• recessive

identical alleles (two caps or two lowercase)
Example: BB, bb   

• heterozygous 
• homozygous
• dominant
• dihybrid

another name for homozygous

• dihybrid
• genotype
• hybrid
• purebreed

another name for heterozygpous

• dihybrid
• hybrid
• genotype
• purebreed

two different alleles (one cap, one lower)

• homozygous
• heterozygous
• offspring
• none of the above

the blending of two traits 

• blending
• recessive trait
• incomplete dominance
• homozygous

1. In a certain species of animal, black fur (B) is dominant over tan fur (b).  
Which type of dominance does this cross show?

• Complete Dominance
• Incomplete Dominance
• Codominance
• Polygenic Inheritance

In cats, long hair is recessive to short hair. A true-breeding (homozygous) short haired male is mated with a long-haired heterozygous female. What will their offspring look like? You may choose more than one answer.

• 50% long haired

• 50% short haired

• 100% short haired

• 100% long haired
