Answer: <em>The Bottleneck Effect</em>
Explanation:
A Bottleneck effect is the sharp reduction of numbers of a population through environmental effects or human activity. It causes a loss of the genetic pool and its variety; genetic variation lowers and increases with time as random mutations occur.
Animals use the respiratory system to breathe in oxygen and other gases and expel gases like CO2, right? O2 in, CO2 out.
Answer:
The correct order would be:
Water evaporates from a lake.
↓
Water vapor condenses to form clouds.
↓
Water falls as rain, snow, and sleet.
↓
Water flows down mountains and hills.
↓
Water joins streams or forms groundwater.
Water cycle refers to the cyclic movement of water in an environment. The water passes through various stages, namely:
evaporation and transpiration
condensation
precipitation
run off
Explanation:
Here we can see that 7 phenotypes appeared in F2 generation, so the number of genes involved is 3 and alleles is 6. Contribution per allele = 4 cm Base contribution = 6 cm
Genotype of Harvey = aa bb cc Genotype of Erma = AA BB CC
Number of dominant alleles if length is
18 cm = 18-6 / 4 = 12 / 4 = 3.
F1 generation genotype = Aa Bb Cc This clarifies why the length is 18 cm, as there are three dominant alleles.
seven 1. It is likely that there are gene pairs in this cross. There are
categories of phenotypes. The genotypes of the parents would be combinations of alleles that would produce a 6 cm ( aabbcc ) tail and a 30 cm) tail, whereas the 18 cm offspring would have a genotype of AaBbcc.
