Round (R) seed shape is dominant to wrinkled (r) seed shape in pea plants. If an RR plant is crossed with an rr plant, what is t
he frequency of phenotypes in the F2 generation? a. All wrinkled seeds b. All round seeds c. 1/4 RR, 1/2 Rr, 1/4 rr d. 3 round seeds, 1 wrinkled seed e. None of the above
If an RR plant is crossed with an rr plant than all the phenotype will produce round seed and the frequency of the Round seed plant to wrinkled seed plant would be 4:0.
R R
r Rr Rr
r Rr Rr
So all the phenotypes will be heterozygous dominant for the round seed which means that all phenotypes will have a single dominant allele for round seed which is enough to express round seeds in the phenotypes.
The biuret solution will turn from blue to purple when it is exposed to protein. The copper sulfate and potassium hydroxide cause the substance to become an alkaline.
Body cells make up the body of any multicellular organism. A body cell contains a complete number of chromosomes and is called a diploid cell while a gamete contains only half the number of chromosomes of its parent cell, and it is called a haploid cell.
