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).

Why is there no external male reproductive organ in a frog?
Morgarella [4.7K]
Frogs reproduce by a special kind of embrace called "amplexus" which is an external fertilization that does not occur inside the female's body.

During mating (amplexus), the male frog grasps the female frog's trunk with his forelimbs.
The female frog discharges eggs into the water and then the male frog sheds the sperms over those eggs.
