. The mean grain yield of an open pollinated rye breeding population is determined to be 72 bushels/acre. Your goal is to improv

e grain yield in this population. The mean grain yield of selected individuals from this population is 93 bushels/acre. Selected individuals are intermated to form a new population. The new population mean is determined to be 84 bushels/acre. With this information, calculate the selection intensity, response to selection and heritability of grain yield. (3) Report your answers for A and B as whole numbers and your answer for C to 2 decimal places.

Answer:

a) the selection intensity is 21bushels/acre

b) the response to selection is 12bushels/acre

c) The heritability is 0.57 (two decimal places)

Explanation:

Given:

mean grain yield population=72bushels/acre

mean grain yield selected individuals=93bushels/acre

mean grain yield new population=84busgels/acre

a) The selection intensity is given by:

SI=mean grain yield selected individuals-mean grain yield population=93-72=21bushels/acre

b) The response to selection is:

RS=mean grain yield new population-mean grain yield population=84-72=12bushles/acre

c) The heritability of grain yield is:

H=RS/SI=12/21=0.57

Answer:

The coral reefs of the Caribbean are thought to be under threat

Explanation:

Overfishing threatens over 60 percent of Caribbean coral reefs. Declines in coral cover and increases in algal cover have been observed across the region. This analysis identified about one-third of Caribbean reefs at high threat from overfishing pressure and about 30 percent at medium threat.

A scientist examines the body fossil and trace fossils left by an
emmasim [6.3K]

Given what we know, we can confirm that as scientists study fossil records, they can learn much about the species, such as the traits and activities of the organisms in question.

<h3>What does each fossil type teach us?</h3>
  • Trace fossils such as footprints can teach us about the activities of the organisms.
  • Meanwhile, scientists will use body fossils to learn about the specific traits of early organisms.
  • Body fossils can at times also provide insight as to the diet of the species.

Therefore, we can confirm that scientists will use body fossils to learn more about the traits and diets of early organisms while using the uncovered trace fossils to track the activities of these organisms.

A recessive allele does not affect the phenotype of a heterozygous person.
Effectus [21]

Answer: A. true

Explanation: The phenotype is the physical characteristics of a person. So, if a person has brown eyes, which may be a characteristic that is dominant, then they would have a genotype of BB or Bb. The reason why Bb, heterozygous, is not a different color is because the recessive b does not affect the dominant B allele.

Hope this helps!!!

Is there any great similarity between the muscle structure and muscle arrangement in the cat and humans?
STALIN [3.7K]
The similarity in the arrangement and structure exists mostly with the quads because we, just like cats, need to be able to flex and extend them so we need a lot of strength in them.
