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

In a pedigree where both parents are heterozygous (Ww) for a gene with complete dominance, what is the probability that their child, individual III-1, is homozygous recessive (ww)?

3. In a population of cats, if the frequency of the dominant allele (A) is 0.7 and the frequency of the recessive allele (a) is 0.3, what is the expected frequency of cats that are homozygous dominant (AA)?

In a population of cats, the allele for short tails (T) is dominant over the allele for long tails (t). If the frequency of the T allele is 0.6, what is the expected frequency of cats with short tails in the population, assuming Hardy-Weinberg equilibrium?

If one parent is heterozygous (Aa) and the other is homozygous recessive (aa) for a dominant gene associated with Alzheimer's disease, what is the probability that their child will inherit the dominant gene?

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 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?
