(WILL GIVE BRAINLIEST ONLY IF CORRECT!!) How is the dispersive model different from the semiconservative model of DNA replicatio

n?
1. In the dispersive model, each strand of both daughter molecules contains a mixture of old and newly synthesized DNA, and in the semiconservative model, each new double helix consists of one old and one new strand.
2. In the dispersive model, the old double helix is degraded, and in the semiconservative model half of its nucleotides are used in the construction of two new double helices.
3. In the dispersive model, one of the two resulting double helices is made of two old strands, and in the semiconservative model the other is made of two new strands.
4. In the dispersive model, one strand of the new double helix is made of DNA, and in the semiconservative model the other strand is made of RNA.

Answer:

1. In the dispersive model, each strand of both daughter molecules contains a mixture of old and newly synthesized DNA, and in the semiconservative model, each new double helix consists of one old and one new strand.

Explanation: it helps to remember that dispersive means to disperse your DNA molecules! And semi conservative means you keep one of your old strands! Hope this helps!

1.

a.  Bb

b. bb

c. Gray, because the male is homozygous recessive, which indicates the recessive trait is black.

d.  Gray-Female, Black-Male

e.      B       b

    b  Bb     bb

    b  Bb    bb

f.  There's a 50% chance the babies will be heterozygous (for gray) and there's a 50% chance the babies will be homozygous recessive for black.

g. There's a chance that all four offspring won't adhere exactly to the ratios predicted by the Punnett Squares, because male offspring can only have one trait (on the X).


Hope this helps. I hope you understand that heterozygous is (Big Letter & Small letter) and homozygous is either: Big Letter Big Letter OR Small Letter Small Letter. Have a great night and I hope you are successful in your class!
