(5.05 mc)fish species a has a gestation time of three months and lays 300 eggs per clutch. fish species b has a gestation time of 5 months and lays 200 eggs per clutch. which fish species would make a better model organism, and why?

Fish species A would make a better model organism. This is because it will have shorter generation times (gestation time of three months) and produce more offspring. An organism is considered a good model organism if it is well understood, can produce a large number of offspring within a short period of time, can grow to maturity rapidly, possess a short life span and can be easily manipulated.

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.

explanation:

hi~~

i would say that hybridization occurs frequently in nature, because there are many types of hybrids that have occurred naturally, such as the mule (male donkey + female horse)
