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.
Answer:
Option (a).
Explanation:
Homozygotes individuals has the same genotype whereas the genotype of the heterozygotes are different. The homozygotes may refer the true or pure organism.
The gametes obatined from the homozygotes caaries the same gene. The gametes of the heterozygotes carries the different version of the gene. The dominant trait will express themselves in the heterozygotic condition.
Thus, the correct answer is option (a).
Hardwood trees have a lot of bark.
(I hope this is good enough.)
Answer:
A closed circuit doesn't allow the flow of electrons. an open circuit does. example: if you turn off a switch in your house. you 'broke the circuit it is closed.
Alright bud the best answer to this question would be that the stratum basale or stratum germinativum which would be the bottom most part of the epidermis has the highest mitotic rate
