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
9:3: 3:1 is the phenotype ratio.
Answer:
The correct answer is option D.
Explanation:
Hamilton rules state that any trait that helps in benefiting others, B, is multiplied by genetic relatedness, R, which is greater than cot to self, C, it is favored by the process of natural selection.
As indicated by Hamilton's rule, the kin selection makes qualities increment in recurrence when the hereditary relatedness of a beneficiary to an actor multiplied by the advantage to the beneficiary is more noteworthy than the regenerative expense to the actor.
Thus, the correct answer is option D.
Rock moves outward, A crack forms, Magma pushes upward, Magma hardens
The pericardial cavity separates the parietal and visceral pericardium
Answer:
Dominant
Explanation:
The dominant allele will always be shown in the phenotype if it's present, because the other allele would be dominant or recessive. If both alleles are dominant, then the dominant one shows, if one of the alleles is recessive, then the dominant allele would show over the recessive one.
I think of recessive alleles as "weak" where, they just follow behind whichever other allele exists there. If the other one is dominant, then the recessive one is behind it, and no one can see it. If it other allele is recessive, a recessive allele will be in front.
