Alenkasestr [34]

Answer:

ZZ species will take more number of crosses to produce a recessive offspring.

Explanation:

Here Z seems to be the dominant allele.  A species having ZZ or homozygous dominant genotype shall not express the recessive phenotype until unless it has both recessive allele and this is not possible as of now or is dependent on the genotype of mating species and the number of generations of development.

If ZZ mates with WW, the offspring in F1 generation will have genotype ZW

However, if the offspring in the F1 generation are crossed then in next generation we could see organism with recessive phenotype i,e WW

ZW*ZW

ZZ, ZW, ZW, WW

While in case of organism having ZW type genotype, recessive phenotype will occur in the first generation cross with the ZW.

Identify the landmark that is not part of the sphenoid bone.
seraphim [82]

The landmark that is not part of the sphenoid bone is Olfactory foramina

Sphenoid bone is are bone that  can be found  at the central  of the human skull and they are made up of  cranial bones  which are bones that help to protect the human brain from injury.

Olfactory foramina is not part of sphenoid bone because  they are hollow space that is found in the cribriform plate.

This hollow space made it possible for the sensory nerves to pass through the  human nasal cavity which in turn help to transport information from the olfactory receptors to the brain.

Inconclusion the landmark that is not part of the sphenoid bone is Olfactory foramina.
