How does polyploidy allow speciation to occur in a single generation? Polyploid offspring produce gametes earlier in the mating

season than than their diploid parents, causing reproductive isolation between the two generations. Polyploid offspring produce smaller gametes that disperse farther than the gametes of diploid parents, causing geographic isolation between the two generations. Physiological differences between polyploid offspring and their diploid parents allow them to thrive in different environments, causing geographic isolation between the two generations. Genomic differences between polyploid offspring and their diploid parents prevent them from successfully interbreeding, causing reproductive isolation between the two generations.

Answer:

Genomic differences between polyploid offspring and their diploid parents prevent them from successfully interbreeding, causing reproductive isolation between the two generations.

Explanation:

Speciation is an ecological and biological process through which new species are formed due to isolation.

In plants, polypoidy involves the possession of two complete sets of chromosomes and it leads to the origin of new species. Also, the two sets of chromosomes comprises of triploidy (69 chromosomes) and tetraploidy (92 chromosomes).

As a result of the genomic differences between polyploid offspring and their diploid parents, this usually prevent them from successfully interbreeding and consequently causing reproductive isolation between the two generations.

When conducting an experiment on how stimuli are represented by the firing of neurons, you notice that neurons respond different
Cerrena [4.2K]

Answer:

Sparse coding

Explanation:

Sparse coding can be described or explained as a situation where items are encoded or represented by strong activation of a relatively small sets of neurons.

It should be understood that neurons code for the intensity of stimulus , and this is done in two ways which are

* Frequency coding...here, the firing rate of sensory neurons increases with increased intensity, and

* Population coding....here, the number of primary afferent responding increases.

In this case, the results derived or gotten from both Arthur's and Roger's faces supported the sparse coding.

What are hyphae made of
postnew [5]
Structure. A hypha consists of one or more cells surrounded by a tubular cell wall. In most fungi, hyphae are divided into cells by internal cross-walls called "septa" (singular septum). Septa are usually perforated by pores large enough for ribosomes, mitochondria and sometimes nuclei to flow between cells.
