Genetics Basics #1

Front

What does the term 'Homozygous Dominant' mean?

Back

An organism with two identical dominant alleles for a trait (e.g., YY).

Front

What does the term 'Heterozygous' mean?

Back

An organism with one dominant and one recessive allele for a trait (e.g., Kk).

Front

What is a 'Genotype'?

Back

The genetic makeup of an organism, represented by the alleles (e.g., TT, Kk).

Front

What is a 'Phenotype'?

Back

The observable physical characteristics of an organism, determined by its genotype.

Front

What does the term 'Homozygous Recessive' mean?

Back

An organism with two identical recessive alleles for a trait (e.g., yy).

Front

What is the difference between Genotype and Phenotype?

Back

Genotype refers to the genetic makeup, while Phenotype refers to the physical expression of that genotype.

Front

What is an example of a Homozygous Dominant genotype?

Back

YY or DD.

Front

What is an example of a Heterozygous genotype?

Back

Kk or Bb.

Front

What is an example of a Homozygous Recessive genotype?

Back

yy or dd.

Front

How can you identify a Heterozygous genotype?

Back

It contains one dominant allele and one recessive allele (e.g., Kk).
