Aplantlike organism on the planet pandora can have three recessive genetic traits: bluish leaves, due to an allele (a) of gene a; a feathered stem, due to an allele (b) of gene b; and hollow roots due to an allele (c) of gene c. the three genes are linked and recombine as follows: a geneticist did a testcross with an organism that had been found to be heterozygous for the three recessive traits and she was able to identify progeny of the following phenotypic distribution (+ = wild type):

The answer is: the B option

Explanation:

The phenotypes of the progeny reveal the allelic content of the gamete from the heterozygous parent.

The purpose of making crosses in genetics is either to obtain progeny of a specific genotype or, working the other way, to use the proportions of different phenotypes of progeny to deduce the genotypes of the parents.

B) The phenotypes of the progeny reveal the allelic content of the gamete from the heterozygous parent.

B) The phenotypes of the progeny reveal the allelic content of the gamete from the heterozygous parent. Theses will reveal the characteristics of a specie due to the interacting with the environment.

phylogenetic tree is the tree of life or evolution tree. it shows the different branches of evolution. the sequence goes like tissues - coelom - backbone - endoskeleton - segmentation

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.
