Answer:
A: A tool for showing possible alleles of offspring in a test cross
Explanation:
Punnet squares use the alleles of the parents to find possible alleles of their offspring.
Answer:
Anthocyanin is not produced in the plant cells
Explanation:
Anthocyanin is not produced in plant cells with the genotype mm.
As you can see from the question above, anthocyanin is responsible for the purple color of the flowers. Anthocyanin is encoded by the M gene, which is a dominant gene. Because it is a dominant gene, we know that it will be expressed in plants with the Mm and MM genotype, but will not be encoded by plants with the mm genotype. With this we can conclude that plants that have the mm genotype do not have purple color, because anthocyanin is not produced in the plant cells of these plants, since they do not have the M gene.

Answer:
•The gene responsible for the albinism is sex-linked
•The gene responsible for the albinism is recessive
• The pedigree is contained in the attached file
Explanation:
The gene responsible for the trait of albinism is said to be sex-linked because all those that were mentioned with the expression of albinism were females
The gene responsible for the trait of albinism is also said to be recessive because it was found to be rarely expressed and this goes in line with the definition of a recessive gene, which says; a recessive gene is the gene that remains unexpressed ( phenotypically) in the presence of it counterpart ( the dominant gene) in an allelic pair.
Answer:
The two forms interbreed and their offspring survive and reproduce well.
Explanation:
When talking about classification of species, one of the first features observed is the species fitness, which describes the reproductive success or their ability to leave to their successive generations the most copies of their genotype. When different species that were recently divided into 2, by geographic isolation, for instance, usually there is no genetic compatibility, and if its possible to produce offspring, there might be some development issues like infertility.
