In a population of butterflies, the allele frequency of A is 0.7 and the allele frequency of a is 0.3. According to Hardy-Weinberg equilibrium, what is the expected frequency of the heterozygous genotype (Aa) in this population?

With four distinct nucleotides, how many different combinations are possible in a sequence of six nucleotides?

What is the probability that the genotype aa will be produced from a cross between two parents with genotype aa x aa?

In a population of cats, the allele for long tails (L) is dominant over the allele for short tails (l). If the frequency of the dominant allele (L) is 0.7, what is the expected frequency of cats with long tails in the population, assuming Hardy-Weinberg equilibrium?

In a population of cats, the allele for long tails (L) is dominant over the allele for short tails (l). If the frequency of the long tail allele (L) is 0.7 and the population is in Hardy-Weinberg equilibrium, what is the expected frequency of cats with long tails?

In a population where the allele frequencies of C and c are 0.7 and 0.3 respectively, what is the expected frequency of the cc genotype under Hardy-Weinberg equilibrium?

In a population of wildflowers where the frequency of the red allele c_r is p = 0.7, what is the expected frequency of homozygous red individuals (c_r c_r) under Hardy-Weinberg equilibrium?

In a family where both parents are heterozygous for a recessive genetic disorder (genotype Aa), what is the probability that, when a couple has two children, both children will be affected by the disorder?
