50%

Is this a dominant or recessive genetic disorder? How do you know?

Recessive genetic disorder, because there are carriers.

Crossing over happens in which phase of meiosis?

Prophase I

B is the dominant allele for big eyes and b is the recessive allele for small eyes.What is the phenotypic ratio of a cross between two heterozygous individual?

Big eyes:small eyes = 3:1

What is fermentation?

An anaerobic process that takes place in the cytoplasm, which functions to regenerate NAD+, so that glycolysis can be continued to produce a small amount of ATP

Which phase is this?

metaphase 2

Which phase is this?
