You know that the narrow-sense heritability of milk production in Ayrshire cattle is 0.587. You perform an experiment where you

take a parental population of cattle with a mean milk production of 5.1L/hr and selectively breed only the top 10% of cows in this population, who have a mean milk production of 8.9L/hr, what is the response to selection (R) in your experiment

Answer:

Explanation:

Narrow sense heritability - h​​​​2

​​​​​​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 = h​​​​​​2S

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

The enzyme telomerase is part protein and part RNA. What would be the most likely effect of a large deletion in the gene that en
Artist 52 [7]

Answer: option A, B and D

Explanation:

The telomeres found at the terminal ends of eukaryotic chromosomes are long repetitive sequences that protects the DNA from being identify as a damage molecule to encourage fusion with other chromosomes. Since replication does not extend down to these 3' ends, the cell recruits the telomerase enzyme which is a ribonucleoprotein that helps to add telomeric repeats using its own RNA component as template to extend this end. Thus if mutation like a large deletion occurs in the gene encoding for this enzyme, the telomerase would not be able to associate correctly with the telomere, the catalytic center also encoding for its RNA polymerase would be altered and the enzymes will not be able to synthesize new telomeric repeats sequences
