Answer:
0.4
Explanation:
Narrow sense heritability is a form of heritability (the other one is broad sense) that is used to describe the percentage of trait variance that is caused as a result of additive genetic factors. It is represented as h² = Va / Vp
Where Va = additive genetic variance
Vp = phenotypic variance
In this case, to get the narrow-sense heritability of pumpkin weight in this population
We have the following
mean weight of original pumpkin patch = 10lbs
weight of a group of original pumpkin = 15lbs
the average weight of offspring pumpkin = 12lbs
Hence we have h² = Va / Vp
= (12 - 10) ÷ (15 ÷ 10)
= 0.4
Ribosomes. Ribosomes which synthesize proteins are found in the rough endoplasmic reticulum.
The specific pattern of genes inherited at conception defines an individual's is genotype.
<h3>
What is a genotype?</h3>
The genotype of an organism is the particular arrangement of alleles for a particular gene.
The term "genotype" refers to a person's entire gene pool. All visible traits for which genes contain the coding are collectively referred to as phenotypes.
There are three types of genotypes:
- homozygous dominant
- homozygous recessive
- heterozygous.
So, The correct option is B.

<span> Decomposition aids farmers, preserves forest health and even helps make biofuels. Decomposers mine them from the dead so that these recycled materials can. Plants use glucose and other sugars to grow and fuel all of their activities, When plants die, carbon and other nutrients stay in their fibers.</span>
