Gene interaction

Red flowers and white flowers are mated together and pink flowers are made.  What inheritance pattern is this?

• law of segregation

• multiple alleles

• complete dominance

• incomplete dominance

All genes have one trait that is dominant over a recessive one.

• True

• False

The difference in epistasis and gene interaction is

• Gene interaction involves two genes

• Epistasis modifies the normal Mendelian ratio

• Epistasis involves two genes

• Gene interaction produces a novel phenotype

In summer squash if you cross different varieties of true breeding sphere shaped squash, you get a disk shaped progeny. What phenomenon is seen here?

• Gene interaction

• Epistasis

• Multiple allele

• Codominance

Gene interaction takes place because

•  A single gene control a single character

• A pair of genes are responsible for a single character

• A pair of genes control two characters

• More than a pair of genes control a single character

Two pairs of non-allelic dominant genes which interact to produce one phenotype is

• Complementary genes

•   Supplementary genes

• Epistasis

• Dihybrid cross

The gene that masks or suppresses other gene is called

• Epistasis

• Hypostatic

• Epistatic

• Complementary genes

Allelic gene interaction:

• Epistasis

• Multiple allelism

• Complementary interaction

• Linkage
