lisabon 2012 [21]

Answer:

Genotypic and Phenotypic ratios → 1:1:1:1

  • 25% of the progeny is expected to be SsWw, exhibiting spotted skin and wooly hair, SsWw
  • 25% of the progeny is expected to be Ssww, exhibiting spotted skin and non-wooly hair, Ssww
  • 25% of the progeny is expected to be ssWw, exhibiting non- spotted skin and wooly hair, ssWw
  • 25% of the progeny is expected to be ssww, exhibiting non-spotted skin and non-wooly hair, ssww

Explanation:

<u>Available data</u>:

  • spotted skin (S) is dominant over non-spotted skin (s)
  • wooly hair (W) is dominant over non-wooly hair (w)
  • Cross: heterozygous spotted, non-wooly mammoth with a heterozygous wooly-haired, non-spotted mammoth.

Parentals) Ssww   x   ssWw

Gametes) Sw, Sw, sw, sw

                 sW, sW, sw, sw

Punnett square)     Sw            Sw           sw           sw

                  sw      Ssww       Ssww       ssww      ssww

F1) 4/16 = 1/4 = 25% of the progeny is expected to be SsWw, exhibiting spotted skin and wooly hair

    4/16 = 1/4 = 25% of the progeny is expected to be Ssww, exhibiting spotted skin and non-wooly hair

    4/16 = 1/4 = 25% of the progeny is expected to be ssWw, exhibiting non- spotted skin and wooly hair

    4/16 = 1/4 = 25% of the progeny is expected to be ssww, exhibiting non-spotted skin and non-wooly hair.

nlexa [21]

Answer:

each new DNA double helix consists of one old DNA strand and one new DNA strand

Explanation:

DNA replication is a semi-conservative process which means a new DNA duplex contains one old DNA strand and one new DNA strand because each DNA strand act as a template strand over which a complementary new DNA strand is made.

So after the completion of DNA replication, each new DNA double helix consists of an old strand of DNA and a new DNA strand. After the replication, only one strand is used for transcription. In RNA formation uracil comes in place of thymine.
