Gametes from both dogs are needed to maintain the correct number of chromosome in the offspring
Explanation:
Reproduction in dogs is a <u>sexual process</u>. During the process, haploid gametes from both the male and the female (sperm from males and eggs from females) fuse together in a process known as fertilization in order to produce <u>diploid offspring.</u>
The haploid gametes ensure that the offspring produced during fertilization has the correct (diploid) number of offspring. Because the production of gametes involves <u>meiosis and crossing over of genetic materials between chromosomes, offspring produced by sexual reproduction are usually genetically different from one another. </u>The random fusion of gametes further ensures that offspring from the same parents are different from one another.
Only a little amount of energy as 10% is transferred to the next trophic level. This is called 10% rule. So, in this case as the energy available at the secondary trophic level is 50 kilocalories and 10% of it is transferred into the tertiary level so it would be 5 kilocalories.
