What causes ocean tides

1 answer:

3 0

Tides are the rise and fall of the oceans. They are caused by the gravity, or pull, of the Moon and Sun. The Moon's gravity is the main force in causing tides. It makes the oceans bulge out toward it. Another bulge occurs on the opposite side, because Earth is being pulled toward the Moon and away from the water. The water on the side farthest away from the Moon is least affected by its gravity.

In horses, Chesnut hair color is recessive to black. The pacing gait is recessive to trotting and long hair is recessive to shor

Vitek1552 [10]

9:3: 3:1 is the phenotypic ratio showing traits as black and long hair : black and short hair: chestnut and long hair: chestnut and short hair when a chestnut horse heterozygous for pacing and hair length with a hybrid horse.

Explanation:

Dominant trait = black hair colour (BB,Bb), trotting (TT,Tt) , long hair (LL,Ll)

recessive trait = chesnut hair colour (bb), pacing gait (tt), short hair(ll)

cross between chestnut horse heterozygous for pacing and hair length will have alleles as BbLl

alleles for hybrid horse will also be heterozygous Bb, Ll

Punnett square to show the cross:

BL Bl bL bl

BL BBLL BBLl BbLL BbLl

Bl BBLl BBll BbLl Bbll

bL BbLL BbLl bbLL bbLl

bl BbLl Bbll bblL bbll

phenotype ratio

black and long hair : black and short hair: chestnut and long hair: chestnut and short hair
