Genetics

What is a phenotype?

• The physical presentation of the genetic expression

• The trait that expresses itself over another

• The gene make-up of a trait expressed as a set of Capital and lower case letter

• The trait that is masked or hidden by the dominant trait.

What is a dominant allele?

• an allele that is not expressed when the dominant allele is present.

• an allele that is always expressed when it is present.

What does Homozygous Recessive look like?

• FF
• ff
• Ff
• fF

What does Homozygous mean?

• Having the same two alleles for a genetic trait.
• Having two different alleles for a genetic trait.

What is a Genotype?

• Having the same two alleles for a genetic trait.
• Having two different alleles for a genetic trait.
• The gene make-up of a trait expressed as a set of Capital and lower case letters
• Offspring having the same homozygous trait as the parent

What is a Hybrid?

• Offspring having the same homozygous trait as the parent

• Offspring having one allele from each homozygous parent

• Offspring having a recessive trait masked by a dominant trait that may express itself in future generations

What does Homozygous Dominant look like?

• FF
• ff
• Ff
• fF

What does Heterozygous look like?

• FF
• ff
• Ff
• fF

What is a gene?

• A length of DNA that contains instructions for making a protein
• a segment of DNA that determines or helps to determine a trait

What does Heterozygous mean?

• Having the same two alleles for a genetic trait.
• Having two different alleles for a genetic trait.
