Carnations with red, smooth petals are crossed with carnations with white, rough petals. In the F1, all the petals are pink and smooth. The F1 intercross yields the following F2:3/16 red, smooth6/16 pink, smooth3/16 white, smooth2/16 pink, rough 1/16 red, rough1/16 white, rougha) What are the parental genotypes?b) What are the F2 genotypes and phenotypes?c) What conclusions can be made about the allelic and gene interactions for both the petal color and texture alleles?

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.

metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). the change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. i hoped i !

the framers of the constitution insisted that federal judges be nominated instead of elected due to their desire to have judges above the shifting whims of the masses.

the hope, whether achieved or not, was that federal judges would only be beholden to the law and that by not having judges be elected, they would be protected if that law dictated an outcome that ran counter to popular opinion.
