If the parents both have the genotype Aa, their children could have the genotypes AA, Aa, or aa. The possible phenotypes for their children would be individuals with type A blood (AA or Aa genotype) or type O blood (aa genotype).
Individuals of the genotype Aa survive best in the environment where the abiotic factors and biotic interactions favor heterozygosity. This can occur when there is a balance between selective pressures that benefit both homozygous genotypes AA and aa.
If the frequency of genotype AA is p^2, where p is the frequency of allele A, then the frequency of genotype AA would be p^2.
Albinism is expressed only in individuals with the homozygous recessive genotype, represented as "aa." This means that both alleles for the trait must be the recessive form for the characteristic to manifest. Individuals with at least one dominant allele ("AA" or "Aa") will not express albinism.
No, a parent with AS and AA genotype cannot give birth to a child with AC genotype. The parent can only pass on either the A allele or the S allele to their child, resulting in genotypes of either AA or AS.
The genotype of pure lines refers to individuals that are homozygous for a particular trait, meaning they carry the same alleles for that trait. For example, in a pure line of plants, all individuals would have the same genotype for a specific gene, such as AA or aa. This genetic uniformity is desired in breeding and research to study the effects of specific alleles.
50% AA and 50% Aa
No because AA and SS create the genotype AS :)
Heterozygotes. If AA X AA, or AA X AA, is all the mating allowed, then Aa will lose frequency in the population.
The AA genotype typically produces the phenotype associated with the dominant allele A. This means that the dominant trait will be expressed in the individual with this genotype.
The offspring's genotype will be AA. Both parents are homozygous dominant, AA, having only dominant alleles to pass on to their offspring. So each parent can pass on only the dominant allele (A) to its offspring. So the offspring will also be homozygous dominant, AA.
When you cross two F1 individuals (both being heterozygous for a trait, for example, Aa), the expected genotype ratio in the F2 generation would be 1 AA : 2 Aa : 1 aa. The phenotype ratio, assuming A is dominant over a, would typically be 3 dominant phenotype (AA and Aa) to 1 recessive phenotype (aa). Therefore, you would expect three individuals displaying the dominant trait for every one individual displaying the recessive trait in the F2 generation.
