Answer:
a) What are the parental genotypes? RRSS and rrss
b) What are the F2 genotypes and phenotypes?
F2) 3/16 RRSS + RRSs (red, smooth)
6/16 RrSS + RrSs (pink, smooth)
3/16 rrSS + rrSs (white, smooth)
2/16 Rrss (pink, rough)
1/16 RRss (red, rough)
1/16 rrss (white, rough)
c) What conclusions can be made about the allelic and gene interactions for both the petal color and texture alleles? For petal color, it occurs incomplete dominance, being R the dominant allele for red and r the recessive allele for white, together expressing pink in heterozygosis. For texture, it occurs complete dominance of the allele codifying for smooth, S, over the allele codifying for rough, s.
Explanation:
Due to technical problems, you will find the complete answer and explanation in the attached files.
In an experiment, using the elodea stalk, you are able to expose more underlying tissue and the process can be executed more quickly and it's easy to replicate the natural position for a more realistic result.
hope this helps
Answer:
Pollution – Construction causes both air and water pollution. Harmful chemicals used during construction can be harmful to both workers and the environment. Waste – The process of constructing new infrastructure produces a lot of waste that ends up in landfills.
Explanation:
People would keep doing the same investigation over and over again and no one would know who did what
