The trait for 'male-pattern baldness' is a recessive trait encoded for by "b". Non-balding is encoded for by a dominant allele encoded for by the letter "B". A street survey conducted by Hair Club for Men found that out of 1000 men, 360 had male pattern baldness, the other 480 who did not and were heterozygous, and 160 who did not and were homozygous for a full head of hair. What are the phenotype ratios? Using this information find the allele frequencies for B and b. What are the expected genotype frequencies?

Explanation:

Given

Non-baldness (B) is dominant on baldness(b), so B is dominant over b.

Homozygous  pattern baldness male (bb) = 360,

Heterozygous  non- baldness (Bb)=  480,

Homozygous non-baldness (BB)= 160.

So, we can also denote then by genotypes  only,

BB= 160;

Bb= 480;

bb= 360;

Total= 1000

Allele frequency q² (bb) = 360/1000=0.36

allele fequency for q( b)= √o.36=0.60.

Allele frequency for p²(BB) = 160/1000=0.16

allele frequency p(B)= √0.16 = 0.4

Expected genotype frequencies;

BB = 160/1000  = 0.16

Bb = 480/1000= 0.48

Bb = 360/1000= 0.36

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.

mientras se trata la anorexia o la bulimia, es importante buscar ayuda antes que nada. un profesional de la salud mental será el más útil para aquellos que sufren anorexia o bulimia. este es un buen lugar para comenzar, sin embargo, ver a otros profesionales como dietistas registrados, especialistas médicos y dentistas podría ayudar a alguien a recuperarse de un trastorno alimentario. después de la ayuda profesional, o si la ayuda profesional no es una opción, alguien que se recupere de la anorexia o la bulimia debe rodearse de compañeros de apoyo, padres u otros miembros de la familia que también estén comprometidos con el proceso de recuperación.

hope this you! : )
