Imagine that a given species has a gene for hair color (B = dominant brown, b = recessive white) and a gene that controls hair l

serg [7]

Answer:

Phenotypes: All Brown Hair Color and All Short Hair Length

Genotypes:

Homozygous dominant hair color and homozygous dominant hair length: (BBSS, BBSS, BBSS, BBSS).

Homozygous dominant hair color and heterozygous hair length: (BBSs, BBSs, BBSs, BBSs)

Heterozygous hair color and homozygous dominant hair length: (BbSS, BbSS, BbSS, BbSS)

Heterozygous hair colour and heterozygous hair length: (BbSs, BbSs, BbSs, BbSs)

Explanation:

Hair color :

B = dominant brown

b = recessive white

Hair length :

S = dominant short

s = recessive long

The dihybrid cross between parents with the genotypes:

BBSS × BbSs

If BBSS self crossed; we have the following traits= BS, BS, BS, BS

If BbSs self crossed; we have the following traits= BS, Bs, bS, bs

The dihybrid cross is as follows:

BS BS BS BS

BS BBSS BBSS BBSS BBSS

Bs BBSs BBSs BBSs BBSs

bS BbSS BbSS BbSS BbSS

bs BbSs BbSs BbSs BbSs

Phenotypes = All Brown Hair Color and All Short Hair Length

Genotypes include:

Homozygous dominant hair color and homozygous dominant hair length: (BBSS, BBSS, BBSS, BBSS).

Homozygous dominant hair color and heterozygous hair length: (BBSs, BBSs, BBSs, BBSs)

Heterozygous hair color and homozygous dominant hair length: (BbSS, BbSS, BbSS, BbSS)

Heterozygous hair colour and heterozygous hair length: (BbSs, BbSs, BbSs, BbSs)

irina1246 [14]

Answer:

enfermedad

Explanation:

De acuerdo a la Organización Mundial de la Salud (OMS) el término enfermedad refiere a la alteración y/o deterioro del estado fisiológico normal de un individuo o partes de su cuerpo, cuyas causas a menudo son conocidas. A su vez, una enfermedad es conocida cuando possee un cuadro clínico con síntomas preestablecidos y característicos. Las enfermedades se pueden clasificar de acuerdo a muchos tipos diferentes de parámetros (por ejemplo, de acuerdo a su modo de transmisión en infecciosas/no infecciosas, hededitarias/ambientales, etc). Por otra parte, el concepto de salud se refiere a un estado de bienestar físico, mental y social del individuo, el cual no solamente está asociado a la ausencia de enfermedades.
