Woman's genotype: ii
Husband's genotype: I^A i
-> possible husband's father genotypes are two I^B and I^B i
-> if husband's father has two I^B alleles, the husband will have one I^B allele present, which is not the case. So, there is i allele present. (can also infer that I^A comes from husband's mother)

Child's possible genotypes:
ii, ii, I^A i, I^A i
probability is 1/2

What do many scientists believe about the purpose for asteroids.
katovenus [111]

Answer:

Various scientists describe asteroids in different ways:

  • Some scientists consider it to be rocks which orbit around the sun.
  • Other consider it to be small planets.

The majority of the scientists agree that asteroids might have come into existence at the time of solar formation. The parts which broke down during the formation of the solar system resulted in the formation of asteroids.

<u><em>Scientists believe that asteroids might not have a major function in the universe but studying them would be of great benefit. This is because as they are parts broken from the solar system, exploring them will let us know about some unknown features of the other solar system bodies. </em></u>

Different organisms have developed varying ways of adapting to these environments, but most scientists agree that it is unlikely that life on Earth originated under such extremes.
