Answer:
There are no chances for this couple to have a child with Tay-Sachs disease. 0% of the possibilities.
Explanation:
Tay-Sachs disease affects the nervous system and is potentially mortal. It is transmitted from parents to progeny. Tay-Sachs is caused by a defective gene in the 15 chromosome.
The child that recesives two coppies of this defective gene, one from the mother and one from the father, results sick. <u>But if only one of the parents transmits the gene, then the child will be a carrier.</u> This child won't be sick but will transmit the gene to his/her own progeny.
<u>Available data</u>:
- The allele for tay-sachs is a recessive allele, "t"
- Tim McGraw to determine is a carrier, Tt
- Tim´s wife is not a carrier, TT
<u>Cross:</u>
Parental) TT x Tt
Gametes) T T T t
Punnet square) T T
T TT TT
t Tt Tt
F1) Progeny genotype: 2/4= 1/2 normal, TT
2/4= 1/2 Carrier, Tt
0/4= 0 Sick, tt
What are the chances they could have a child with Tay-Sachs?
There are 0% of the possibilities that this family will get a sick child.
