Probability & Chromosomes

Alleles that are present in a genotype but are not expressed are called

• recessive

• masked

• hidden

• dominant

After observing dihybrid crosses, Mendel concluded that the presence of one trait didn't affect the presence of another. This is called

• The Law of Inheritance

• The Law of Segregation

• The Law of Natural Descent

• The Law of Independent Assortment

A __________ is the visible trait or physical appearance.

• Genotype

• Dominant

• Co-dominance

• Phenotype

When the genotype has 2 identical alleles it is known as...

• Heterozygous

• Co-dominance

• Homozygous

• Recessive
