BlackZzzverrR [31]

Answer:

Probability that both cats described will have an offspring who is heterozygous for both traits is 50%, according to the scenario given.

Explanation:

When a cat amazing and bashful is crossed with a cat average and boring, it is a crossing where two traits are taken into account that will be segregated independently by the parents, and the result can be obtained by analyzing their genotypes and making the corresponding crossing in a Punnett square.

<u>Genotypes</u>:

  • <u>Male cat</u>  AABb
  • <u>Female cat </u> aabb

<u>Crossing</u> :

Punnett's square (simplified)

<em>Alelles       AB      Ab</em>

<em>ab            AaBb  Aabb</em>

<em>ab            AaBb  Aabb</em>

<u>Offspring</u>:

  • <em>AaBb amazing and bashful (heterozygous for two traits) 50%</em>
  • <em>Aabb amazing and boring (heterozygous for trait A ans homozygous recessive for B) 50%</em>

<u><em>Probability that they will have an offspring who is heterozygous for both traits is 50%.</em></u>

just olya [345]

Answer:

Anaphase of meiosis II

Explanation:

During Anaphase II, the spindle fibers pull the sister chromatids apart, toward the opposite poles of the cell. I recommend searching Anaphase II up and looking at a picture. It will give you a better visual understanding.
