Genetics

What is the definition of Homozygous

• Two different allels

• Two of the same allels

• Two of the same chromosomes

• Two different chromosomes

What is the definition of Heterozygous

• Two different alleles

• Two of the same alleles

• Two of the same chromosomes

• Two different chromosomes

What is the definition of phenotype

• The physical characteristics of offspring

• The genes of offspring

• How the offspring behaves

• The traits of the offspring

What is the definition of genotype

• The physical characteristics of an offspring

• The genes of a offspring

• The way the offspring behaves

• The traits the offspring have

What is the definition of codominance

• One set of genes is dominant

• One set of genes are recessive

• Both set of genes are recessive

• Both set of genes are dominant

which of the following is the definition of recessive

• Trait that will only appear in the phenotype if organism inherits two of them; covered up by the dominant gene.

• Trait that will show up in an organism's phenotype if gene is present.

• Offspring of a cross between parents with different traits.

DD is an example of

• homozygous dominant

• dominant

• homozygous recessive

• recessive

Dd is an example of

• homozygous dominant

• heterozygous gene

• Heterozygous recessive

• recessive

phenotypes that shows both traits are

• codominant

• homozygous dominant

• Homozygous recessive

A simple genetic rule where a gene only in dominant or recesssive forms

• Phenotype

• Genotype

• mendelian inheritance

• Allele
