<1>what are phenotype?

<2>what are the Kid's genotype???

Answer 1

1. Phenotype of the Parents?  AB X AB; AO X BO

2. Kids:  AO, BO, AA, BB

Answer 2

ok, this works better if you draw a punnent square.

Let&#039;s take a different question since you did not provide it in punnet square form. Let&#039;s take eye color. Brown eyes are the trait that is dominant. So (BB). Blue eyes are recessive (bb).

Now if a man (BB) marries a woman (bb). The Genotype of the children looks like this...

     b    b

B  Bb  Bb

B   Bb Bb

That is the genotype Think about the word. Gene. I listed the possible genes. Bb, Bb, Bb, Bb. A very certain chance the baby is gonna have brown eyes.

Now the phenotype is what it actually is.

So if a woman is pregnant, the phenotype is unknown until the baby comes out. If the baby comes out with brown eyes, that is the phenotype.

Now in your example the phenotypes of the 2 sons are blood type A, and for the daughter is bloodtype B.

Sketch the punnent square for the genotypes, and write down the possiblilites.

Hope this helps.

put me as your best score plz.:)

Answer 3

Sons would be AO or AA - this is the genotype. Phenotype is the blood group = Group A.

Daughter would be BO or BB - this is the genotype. Phenotype is the blood group = Group B.

Parents = AO (groupA) &amp; BO (GroupB) giving AO,BO,OO &amp; AB as possibilities.

or, OO (GroupO) &amp; AB (Group AB) giving AO,BO as possibilities.

or,AB &amp; AB giving AA,BB,AB &amp; AB as possibilities.

or,AB &amp; AO giving AA,AO,AB &amp; BO as possibilities.

or,AB &amp; BO giving AB,AO,BB &amp; BO as possibilities.
