Question

Mother's Blood Type: B Child's Blood Type:O Suspected Dad's Dad's potential Explain why / why not suspect Blood type genotypes #1AB #2 O #3 A #4B Solving Genetics Problems: Incomplete Dominance 10. In chickens, an incompletely dominant allele (B) results in a mostly white feathers (Splash), the recessive allele (b) results in black feathers. The heterozygote (Bb) has gray-blue feathers. Egg color, however, is due to either a completely dominant allele E (Brown eggs) or a recessive allele e (white eggs) If we cross two dihybrid blue, brown egg laying chickens, what percent of the offspring would you expect to have the following phenotypes: b. Splash chickens that lay brown eggs: c. Splash chickens that lay white eggs d. Blue chickens that lay brown eggs: e. Blue chickens that lay white eggs: f. Black chickens that lay brown eggs: g. Black chickens that lay white eggs: Squash color can be white, yellow or green. The three colors are due to two different genes, the A locus and the Y locus. The dominant allele A is epistatic over the Y locus, producing a white fruit. If the dominant allele A is not present, the fruit will either be yellow (YY or Yy) or green (bvy) 11.

Explanation / Answer

Allele for the following blood groups-

A- IAIA or IAIO

B- IBIB or IBIO

AB- IAIB

O- IOIO

Mothers blood type is B and childs Blood type is O and the child (IOIO) must get his two Io allele from both parents. So the mothers genotype is IBIO.

10. The genotype of the two parents Dihybrid blue feathered brown egg laying is BbEe X BbEe

Splash chicken that lays brown eggs-3/16*100= 18.75%

Splash chicken that lays white eggs-1/16*100=6.25%

Blue chicken that lays brown eggs-6/16*100= 37.5%

Blue chicken that lays white eggs-2/16*100= 12.5%

Black chicken that lays brown eggs- 3/16*100= 18.75%

Black chicken that lays white eggs-.1/16*100= 6.25%

AB IAIB Not a suspect because the father must have one of the following genotype IBIO OR IAIO OR IOIO O IOIO A suspect because fathers potential genotype should be IBIO OR IAIO OR IOIO A IAIO A suspect because fathers potential genotype should be IBIO OR IAIO OR IOIO B IBIO A suspect because fathers potential genotype should be IBIO OR IAIO OR IOIO
