So Mendel got roughly 75% yellow and 25% green in f2. This means that f1 contains all heterozygous genes, as shown below
Y y
Y YY Yy
y Yy yy
Summary: 75% YY or Yy, 25% yy
Which means that green (y) is a recessive phenotype, while yellow (Y) is a dominant phenotype, since plants with heterozygous genotype Yy express the yellow trait.
Arctic/Polar is the best answer
Answer:
In a stable population, if all the other factors are equal then the birth rate should be equal to the death rate in order to maintain the stability.
Explanation:
The birth rate is described as the number of births taking place in an area per year. Death rate is described as the number of deaths taking place in an area in a year.
In order to maintain a stable population, the birth rate should be equal to the death rate. If there are more number of births than the number of deaths, then it would mean more competition for resources like food, water etc.
