1. John has tyoe o blood. His child has type A blood. What type of blood Could his mother have? Draw Punnett squares. 2. artan\'s syndrome is caused by an autosomal dominant altele. What are chances of having a child that will develop syndrome if one of the parents has Marfan\'s syndrome. \"President Lincoln may have had 3. The allele for green skin color frogs) is .2 and the allele for yellow color What would the probabilites phenotypes, d genotypes of all offspring from two Brown skin is dominant over yellow in snake skin. Smooth scales are all dominant Show a Punnett square that would show genotypes and probabilities of a cross between a yellow skinned 4. 5. In the and a brown rough skinned snake. were question above how would you know whether the offspring heterozygotes or true breeding for dominant traits?

Solution

Answer:

1)

John has O blood group, so genotype is \"I^OI^O\"

Mother blood group---?

child blood group --- A,         so genotype is I^AI^A or I^AI^O

Child genotype can be either I^AI^A or I^AI^O

Based in chidren blood group, if we cross father blood group with A, then..

1) I^OI^{O X} I^AI^A

2) I^OI^{O X} I^AI^O

From the above , we can say that mother blood is A, and genotype can be I^AI^A orI^AI^O

	IA	IA
IO	IAIO	IAIO
IO	IAIO	IAIO
