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

9:3: 3:1  is the phenotype ratio.

What is a positive and negative impact? (Human impact on the environment. write a summary.)
Nataliya [291]

Human collaboration inside environments can contrarily affect the degrees of biodiversity. The effect of an increment in the human populace, including expanded waste, deforestation, peat swamp obliteration and an Earth-wide temperature boost has been to decrease biodiversity. Protection, the safeguarding of environments and the organic entities inside them, helps invert this.

Hope this helps:)

Why do scientists often take more than one representative sample
adell [148]

A representative sample is a reflection of the characteristics of the certain group ( population) as a whole. Sample size is the number of representative samples (individual pieces of data) used to calculate a set of statistics. The greater this number the better the determination of the average values of their data. Having greater number of samples also avoids errors from testing a small number of possibly atypical samples.
