Albinism – insufficient pigment – is

caused by a recessive allele.

person (remember to select your

Write the genotype of a

heterozygous ugly haired,

homozygous albino, heterozygous

tongue painting tool, homozygous taster.

Remember, you should have two

alleles for each trait

C=curly, c=straight

N=normal color, n=albino

R=roller, r=non-roller

T=taster, t=non-taster

 CcnnRrTT

 Write

the phenotype to get the

next person applying

these letters to your alleles

C = frizzy hair, c sama dengan straight hair

N sama dengan normal color, n = albino

R = tool, r sama dengan non-roller

Capital t = taster, t sama dengan non-taster

A spotted bunny when entered with a

sound colored bunny produced most

spotted children. When these F1

rabbits were crossed within

themselves, they made thirtytwo noticed rabbits and ten solidcolored rabbits. Which usually characteristic is dependent on the

prominent allele?

32 noticed, 10 solid-colored

 � ~ three or more: 1 ratio of spots: solids

 Therefore , the spotted allele is

dominating

How most of the spotted rabbits

in the F2 generation inside the

preceding problem would be

expected to be homozygous?

How lots of the solid-colored F2

rabbits can be homozygous?

In guinea domestic swine, the layer may be

hard or soft.

Certain difficult coated guinea pigs when

crossed with smooth lined guinea

pigs produce all rough children.

Other tough coated guinea pigs once

crossed with smooth lined guinea

domestic swine produce equivalent numbers of rough

and soft coated guinea pigs

Smooth layered guinea pigs

crossed together always develop

smooth coated offspring

Yellowish guinea pigs crossed with white

types always generate cream colored

offspring.

Two cream shaded guinea domestic swine, when

crossed together, produce yellow, cream

and white-colored offspring in a 1: two: 1 proportion.

How are these kinds of colors passed down?
