In a hypothetical population of plants, flower color is determined by a single gene with two alleles. In a population of 500 pla
blondinia [14]

Answer:

In the F1 generation

RR = 0%

Rr = 50% (or 0.5)

rr = 50% (or 0.5)

Explanation:

A pink flowering plant has the genotype Rr. It is heterozygous for the allele. The alleles for this gene appears to show incomplete dominance, as the heterozygous phenotype is a blend of the two homozygous genotypes.

A white flowering plant has the genotype rr. It is homozyogous for the white allele

A punnet square of the cross is shown.

The resulting punnet square shows that only Rr and rr genotypes are possible, at a ratio of 50:50 (or 1:1). Therefore, the genotype frequency of Rr is 50%, and rr is 50% in the F1 generation. This can also be written as 0.5. It is not possible to get a red plant, as the genotype RR can not come from this cross

Is the heme molecule attached to hemoglobin during the primary level or tertiary level of organization?
djyliett [7]

Answer:

Tertiary.

Explanation:

Primary structure of proteins refers to the order of amino acids that make up the protein. The heme is an nonprotein non-amino acid, so it is not involved at this stage.

Tertiary structure of proteins is the overall 3-D folding of the protein (it comes after secondary, which involves folding into a repeated pattern). The heme bonds to its correct position on the hemoglobin during this stage and helps in correct folding.
