The possible scenario for singing traits in female birds will be about 26% in Generation 4 species
Explanation:
Singing trait have been common among both male and female birds and it is an ancestral traits. However, singing has been more sex-specific with male birds. Reasons for which birds generally sing are:
- To attract the mates
- While making nests and laying eggs
- For the young birds to recognize their parents
However, various studies prove that the singing trait in female birds is reducing with increase in non-singing female birds over the years due to evolutionary course.
Answer:it described how carbon is recycled between earth's biosphere, hydrosphere, geosphere and atmosphere. Carbon is an essential element for all life forms so understanding how it is recycled will help us to understand factors and all the biological processes that influence them.
Explanation:
Answer: The environment changed suddenly from a shallow ocean setting to a river system.
Explanation: Changes seen in rock layers represent changes in Earth's local history. The rock layer stack overall shows a shallow ocean setting. But the youngest layer at the top was deposited by a river. This shows the geologist that the local environment changed suddenly from an ocean setting to a river system.
Answer:
Explanation:
Narrow sense heritability - h2
selection differential - S
Selection differential is calculated from the difference between the population average and the parental population.
Breeder's equation:
Response to selection - R = h2S
Mean milk production of 10% cows for experiment = 8.9L/hr
Mean milk production of parental population = 5.1L/hr
Selection differential S= 8.9 - 5.1 = 3.8 L/hr
Response to selection = 0.587 × 3.8 = 2.23
