So, you would make a punnet square. You would put the capital S and lowercase s on the top of it and then the capital Y and lowercase y on the side. Then you should have SY, sY, Sy, and sy as your outcomes.
<span>The Calvary is a work by Cheri Samba, an African artist who represented works of painting with themes of the reality of life in Africa, such as life, routine, economic problems and society in general. The Calvary is one of his most famous works and contains some violence because it represents images of pain and anguish in each stroke leaving traces and accounts of the feelings found in his works.</span>
Answer:
A
Explanation:
Biofilms are a colony of bacteria that secrete a layer of extracellular matrix (made of polymeric substances of proteins or polysaccharides) that is hard to penetrate with antibiotics. The bacteria in the biofilm also function in coordination and are able to adapt to different factors hence making them hard to eradicate. They can be found in the inside surface of sewage pipes.
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:
F1 Generation:
- Genotype: 100% RrPp
- 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)
