Sati [7]

Answer:

The inheritance pattern is CODOMINANCE

Explanation:

Codominance is a type of non-mendelian inheritance i.e. does not follow Mendel's principles of inheritance, in which two alleles of a gene are both dominant, hence, they are both simultaneously expressed in that gene.

Examples or cases of codominance are the AB blood type in humans where alleles A and B are both expressed in the gene. Also, red and white striped flowers in certain plants is an example of codominance as red and white alleles are both expressed.

A researcher investigates a recently discovered species of plant. The plant has vascular tissues and exhibits a sporophyte and a
Anna71 [15]

The plant contains vascular tissue and has an alternation of generation. But, it lacks seeds. So, the plant is a Pteridophyte.

  • Vascular tissues are absent in thallophytes and bryophytes. They are found in pteridophytes, gymnosperms and angiosperms.
  • The sporophyte and gametophyte generation is common in bryophytes and pteridophytes.
  • Seeds are produced in plants that come under the group gymnosperms and angiosperms. The presence of seeds is the main characteristic of these groups.
  • Thallophytes, bryophytes and pteridophytes lack seeds. The reproduction in plants that comes under these groups occurs with the help of spores.

Thus, the recently discovered species of the plant should be classified based on the presence of vascular tissues, gametophytes and sporophytes. As pteridophytes contain vascular tissues, sporophytes and gametophytes and lack seeds, the plant is a pteridophyte
