Genetics

Different forms of a single gene.

• Genotype

• Chromosome

• Trait

• Allele

When 2 different dominant traits are inherited and they are both expressed.

• Incomplete Dominance

• Co-Dominance

• Recessive

• Punnett Square

The trait that always appears in the offspring if it is present.

• Dominant

• Recessive

• Hybrid

• Incomplete Dominance

Segments of DNA that carry hereditary information and are passed from parent to offspring.

• Chromosomes

• Probability

• Ressesive

• Genes

What an organism physically looks like.

• Genotype

• Phenotype

• Chromosomes

• Traits

A trait the recedes into the background or is present in the alleles but hidden in appearance.

• Dominant

• Pure

• Hybrid

• Recessive

B=brown eyes
b= blue eyes
What is true about two brothers that have brown eyes?
One has genotype BB the other Bb.

• they have same phenotype and genotype
• they have different genotypes and phenotypes
• they have same phenotype but different genotypes
• they have same genotype but different phenotypes

W=white hair
w= non-white hair
If you cross a horse with WW and a horse with ww what fraction of the offspring would be expected to have white hair?

• none
• 3/4
• 1/2
• all

Which of the characteristics is a lion least likely to pass on to its offspring?

• fur color
• length of tail
• scars on leg
• body size

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

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