The syntenic genes A and Z are linked. A cross between two parents, AAZZ and aazz, produces F1 progeny with the AaZz genotype. W
garik1379 [7]

Answer:

The possible arrangements of alleles on the F1 progeny's chromosomes will be AZ/Az or aZ/az

Explanation:

The genotype of F1 progeny  is AaZz

The allele pair of gametes would contain one allele for characteristic represented by "A or a" and other allele for characteristic represented by Z or z"

Thus, total four allele pairs will be formed.

First allele pair would be - AZ

Second allele pair would be - Az

Third allele pair would be - aZ

Fourth allele pair would be - az

Hence, the possible arrangements of alleles on the F1 progeny's chromosomes will be AZ/Az or aZ/az

A researcher collects what appears to be a new species in a freshwater stream. Microscopic analysis shows the presence of chloro
algol [13]

According to the research, this new species most likely belongs to the Protista kingdom since it has a defined nucleus.

<h3>What is the Protista kingdom?</h3>

They are unicellular or multicellular microorganisms that, for the most part, feed autotrophically, and that, on the other hand, cannot be included in the remaining three kingdoms of eukaryotes.

It can be both autotrophic and heterotrophic by photosynthesis, although many of them combine both forms of nutrition and have chloroplasts, mitochondria, a defined nucleus, among other structures.

Therefore, we can conclude that according to the research, this new species most likely belongs to the Protista kingdom since it has a defined nucleus.
