The mutation was most likely the result of a change in the ability of the  DNA replication.

<h3>How mutation occur?</h3>

Mutations result either from errors that occurs in DNA replication or caused by the mutagens, such as chemicals and radiation, which react with DNA and change the structures of individual nucleotides so we can conclude that the mutation was most likely the result of a change in the ability of the  DNA replication.

In roosters, two genes determine the shape of their comb. The R_pp produces a rose comb, rrP_ produces a pea comb. When both gen
oksian1 [2.3K]

The genotype ratio is the proportion of different genotypes observed in the next generation from a genetic cross. The phenotypic ratio is the proportion of phenotypic traits observed from a genetic cross.

In this case, the genetic cross between a rose comb rooster (RRpp) and a pea comb rooster (rrPP) will produce the F1 generation:

  • Parental gametes: Rp; rP
  • Cross: Rp x rP

F1 Generation:

  1. Genotype: 100% RrPp
  2. Phenotype: 100% walnut comb (R_P_)

F1 gametes:

  • 1/4 RP; 1/4 Rp; 1/4 rP; 1/4 rp

Punnett square segregate alleles (F2):

                   1/4 RP             1/4  Rp               1/4 rP              1/4  rp

1/4 RP      1/16 RRPP        1/16 RRPp          1/16 RrPP         1/16 RrPp

1/4 Rp     1/16 RRPp         1/16 RRpp         1/16 RrPp         1/16 Rrpp

1/4 rP       1/16 RrPP          1/16 RrPp          1/16 rrPP          1/16 rrPp

1/4 rp       1/16 RrPp          1/16 Rrpp          1/16 rrPp           1/16 rrpp

Hence, the genotypic and phenotypic ratios in a cross between two F2 will be:

Genotypic ratio F2:

  • 1/16 RRPP
  • 1/8 RRPp
  • 1/16 RRpp
  • 1/8 RrPP
  • 1/4 RrPp
  • 1/8 Rrpp
  • 1/16 rrPP
  • 1/8 rrPp
  • 1/16 rrpp

Phenotypic ratio F2:

  • 9/16 walnut comb (R_P_)
  • 3/16 rose comb (R_pp)
  • 3/16 pea comb (rrP_)
  • 1/16 single comb (rrpp)
