In fact, the concordance rate of autism spectrum disorder was twice in identical twins that of non-twin siblings.
It has been shown that genetic has a huge influence on the development of autism spectrum disorder and that autism in identical twins was 13 times that of the general population. This suggest that environmental factors in the womb are the major factors that contribute.
Answer:
External factors include physical and chemical signals. Growth factors are proteins that stimulate cell division. – Most mammal cells form a single layer in a culture dish and stop dividing once they touch other cells. Two of the most important internal factors are kinases and cyclins.
<h2>
Answer:</h2>
<u>B. Spores</u> are involved in both sexual and asexual reproduction.
<h2>
Explanation:</h2>
In science, a spore is a unit of sexual as well as asexual proliferation that might be adjusted for dispersal and for endurance, frequently for expanded timeframes, in troublesome conditions.
Bacterial spores are not part of a sexual cycle but rather are safe structures utilized for endurance under horrible conditions. Under good conditions, the spore can form into another living being utilizing mitotic division, delivering a multicellular gametophyte, which inevitably proceeds to create gametes.
Answer:
The environment cannot influence that trait.
Explanation:
Heritability refers to the measure of the differences in the gene of a person and how the genes are influenced by the environmental factors and controls the trait.
The heritability is counted between 0 to 1 which is counted on the measure of how the gene is influenced by the environment.
In the given if the heritability is very high that means close to 1 therefore it means the trait is controlled only by the genetics of the person and least influenced by the environmental factors.
Thus, the selected option is correct.
