In some goats, the presence of horns is produced by an autosomal gene that is dominant in males and recessive in females. a horned female is crossed with a hornless male. the f1 offspring are intercrossed to produce the f2. what proportion of the f2 females will have horns?

of the f2 females will have horns

Explanation:

Let the "presence of horn" trait be represented by "H"

and the "absence of horn" trait be represented by "h"

Given presence of horn is a dominant trait in males and recessive trait in females.

F1 Cross -

Horned female genotype - HH

Hornless male genotype - hh

HH * hh

Hh, Hh, Hh, Hh

F2 Cross

Hh * Hh

HH, Hh, Hh, hh

Only one female will have horns

of the f2 females will have horns

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
