Aresearch team studied a large lizard population in the sonoran desert of arizona. in these lizards, gene a is one gene that affects the color pattern on the dorsal surface of the lizard’s body. in 2010, the research team sampled a large number of lizards and determined the genotypes of the lizards for the a gene. they found the following genotype frequencies: a1a1 = 0.17, a1a2 = 0.15 a2a2 = 0.68. what is the frequency of the a1 allele? 0.49 0.5 0.34 0.17 0.245 0.755 0.15

Option A,

Explanation:

As per Hardy Weinberg equation -

is the frequency of occurrence of genotype

The frequency of allele will be equal to square root of frequency of

Substituting the given value in above equation, we get -

Frequency of allele

Frequency of allele

Frequency of allele

So the nearest option is option , i.e option A

meiosis is the correct answer

oxygen is the first element in group 16 (via) of the periodic table. the periodic table is a chart that shows how chemical elements are related to each other. the elements in group 16 are said to belong to the chalcogen family. other elements in this group include  sulfur, selenium, tellurium,  and  polonium.  the name chalcogen comes from the greek word  chalkos,  meaning "ore." the first two members of the family, oxygen and sulfur, are found in most ores.

oxygen is by far the most abundant element in the earth's crust. nearly half of all the atoms in the earth are oxygen atoms. oxygen also makes up about one-fifth of the earth's atmosphere. nearly 90 percent of the weight of the oceans is due to oxygen. in addition, oxygen is thought to be the third most abundant element in the universe and in the solar system.
