#Unit 4. Cell Communication and Cell Signaling
  1. All receptors on a single B cell have shown different  specificity for antigen.

  2. Daughter cells within each clone would be able to secrete large amounts of antibody to neutralize the pathogen

  3. Clone of cells having the identical receptor as the parental B cell

  4. these clones would migrate to, and function within, the primary as well as secondary lymphoid organs

A locus determines the type of pigment produced in the squash, with yellow (Y_) dominant over green (yy). This locus is expressed only in ww plants, which lack the dominant inhibitory allele W. We can assign the genotype ww Y_ to plants that produce yellow squash and the genotype ww yy to plants that produce green squash. The genotypes and their associated phenotypes are:

#Unit 8. Inheritance Biology

The interaction of two loci that determine fruit color in summer squash, which is commonly found in one of three colors: yellow, white, or green. When a homozygous plant that produces white squash is crossed with a homozygous plant that produces green squash and the F1 plants are crossed with each other, the following results are obtained:

 12/16 plants with white squash

 3 /16 plants with yellow squash

 1 /16 plants with green squash

 This is the case of___
