In maize, a dominant allele A is necessary for seed color, as opposed to colorless (a). Another gene has a recessive allele wx t
Gelneren [198K]

Answer:

  • 1/2 Aa Wx wx (colored seeds, normal starch)
  • 1/2 aa Wx wx (colorless seed, normal starch).

Explanation:

  • A (colored seed) is dominant over a (colorless)
  • Wx (normal starch) is dominant over wx (waxy)

Both loci are independent.

A <em>Aa WxWx </em>individual was test crossed (crossed with a homozygous recessive <em>aa wxwx</em> individual).

  • The homozygous recessive can only produce <em>a wx </em>gametes.
  • The dihybrid individual can produce two types of gametes, all of them with the same frequency because the genes segregate independently: 1/2 <em>A Wx </em>and 1/2<em> a Wx </em>

<u>The possible offspring resulting from the combination of those gametes is:</u>

  • 1/2 Aa Wx wx (colored seeds, normal starch)
  • 1/2 aa Wx wx (colorless seed, normal starch).
