This can be solved either by using a Punnet Square or you can use the formula (n(n+1))/2, where n is the number of alleles. However, using either method will give you the number of possible genotypes regardless if it's homozygous or heterozygous. If we use the second formula, that will give you 10 possible genotypes. Since you only want to know the number of heterozygous genotypes, you should subtract the number of possible homozygous genotypes. In this case, there are four. That is (A1,A1), (A2,A2), (A3,A3), and (A4,A4). Knowing this, you'd be able to figure out that there are six heterozygous genotypes.
(A1,A2), (A2,A3), (A3,A4), (A1,A4), (A1,A3), (A2,A4)

<span>The correct answer is desert biome.</span>
Deserts are regions also called drylands because of the conditions found there (like a moisture deficit). Desert plants have to adapt to those dry and hot climates (sometimes without fresh water for years). Some plants have adapted by growing long roots that tap water from deep underground. Others, such as cacti, have special means of storing and conserving water (modifications of leaves for example).
Answer:
Different latitudes on Earth receive different amounts of sunlight, and are a key ... sometimes receiving as little precipitation as the world's driest deserts. ... these high-latitude regions, but even less melts due to the cold temperatures ... the 'temperate' climate can experience both arctic and tropical weather in the same year.
Explanation:
