Iwill give you as much as points you want just answer right now and ! 1 in one type of plant, orange petals (o) are dominant over yellow petals (o) and tall stems (t) are dominant over short stems (t). complete a dihybrid cross for parents with the genotypes: oott × oott and answer the following in complete sentences. describe how you would set up a punnett square for this cross. list the likelihood of each possible offspring genotype. list the likelihood of each possible offspring phenotype.

We first check the first parent's possible alleles: OT, Ot, OT, Ot. (Combinations of the 2 O-alleles and T-alleles given).
A similar process is used for the second: OT, Ot, oT, ot

Genotypes: Check the attachment. We combine the alleles from each parent (for example, Ot + oT = OoTt). We do this for all 16 combinations.

Genotype Likelihoods: We count each of the possible results and tabulate the number of times each appears, and divide by the total number of combinations (16).

OOTT: 2/16 = 1/8 = 0.125

OOTt: 4/16 = 1/4 = 0.25

Oott: 2/16 = 1/8 = 0.125

OoTT: 2/16 = 1/8 = 0.125

OoTt: 4/16 = 1/4 = 0.25

Oott: 2/16 = 1/8 = 0.125

Phenotypes: Check attachment. Based on the genotypes, use the dominant gene if at least one is dominant (Ex. Oo = O, oo = o)
Phenotype Likelihoods: We count the number of each possibility, only 2 of which are present: OT and Ot, then divide by the total number of combinations, which is 16.

OT: 12/16 = 3/4 = 0.75

Ot: 4/16 = 1/4 = 0.25

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.

explanation:

carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite   shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.
