Feather color in Christmas Parrots is codominant. You have 2 Christmas Parrots each red and green. What are the percentages for each phenotype?

The percentage of each phenotype to be expressed is *50%* each

Explanation: In codominance, two alleles for a particular trait are equally expressed in an individual carrying it, neither an allele is dominant or recessive over the other. In this case the individual shows the two traits of the allels.

Furthermore, when 2 Christmas parrot are crossed with red and green color in an homozygous codominant trait the heterozygous F1 generation will either be red with traces of green or green showing traces of red.

If parrot 1 (Red) is represented as PR PR and parrot 2 (Green) is PG PG the cross between them will give PR PG therefore, the individual shows both traits.

chromosomes carry the genetic information for organisms. also, chromatin is the thread like dna which is located in the nucleus of an organism.

the sugar-phosphate backbone forms the structural framework of nucleic acids, including dna and rna. this backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.
