The proportion of progeny that will be ww ee ff if F1 is testcrossed. Introduction: An autosomal recessive trait that is the individuals with a shaded in the symbol are homozygous recessive (aa) and show the recessive trait. A half-shaded symbol represents heterozygous individuals (Aa), and an unshaded symbol represents individuals who are homozygous dominant (AA).

Answer 1

Question

Features of a Concept Features of a Concept Characteristics are discrete; that is, they are unitary. Genetic features have alternative forms, and each feature is inherited from one of the two parents. These are called alleles. One allele is dominant over the other allele. The dominant allele is reflected in the phenotype. Random segregation creates the gametes. The heterozygotic individuals produce gametes with an equal frequency of both alleles. Genes are unlinked; that is, different traits arise from the independent assortment.

If PCR was performed on the fragment of DNA shown below using "5'-TAGG-3" and "3'-TCTA-5'" as the primers, how many base pairs long would the PCR product be? To help with this, remember the antiparallel structure of DNA and that primers are complementary and antiparallel to the target sequence that they bind to.
