What is the phenotype ratio of hhgg hhgg

The phenotype ratio of HhGg x HHGg is 9:3:3:1.

Explanation:

The phenotypic ratio is concerned with the relative number of the offspring man manifesting a particular trait or combination of traits. It can be determined by making test cross and then finding the frequency of the traits.

phenotype ratio of HhGg HHGg is a different di-hybrid cross. One 'g' will be combined with the one 'h'. In result the huge will be dominant that of small and green will be dominant to that of blue.

HhGg × HhGg ( huge/green × huge/green)

From the below stated table we can conclude the ratio which is like huge/green =9,

Small/green = 3,

huge/blue=3,

small/blue = 1.

Hence it is proved that the phenotypic ratio will be  9:3:3:1.

the menstrual cycle – higher tier. negative feedback mechanisms affect the production of hormones in the menstrual cycle. oestrogen also stimulates the release of lh (luteinising hormone) from the pituitary gland, which in turn controls the production of progesterone.
