Answer:

The correct answer is the opposite of the positive phototropism.

Explanation:

The vines in the tropical rain forests in the given case would primarily exhibit the growth pattern opposite in the direction of positive phototropism. The response of the plant towards the source of light is termed as the positive phototropism. On the other hand, the phenomenon that results in the growth of the plant in the reverse direction is termed as negative phototropism.

Thus, in the given case, in order to reach a large tree, the vines in the tropical rain forests would primarily show a growth movement, which would be the opposite of positive phototropism.

Sex-linked traits punnet squares - please help walk me through it! I’m so confused haha
m_a_m_a [10]

Explanation:

a) The allele for hemophilia is Xh and that for normal is XH.

Crossing a hemophiliac male, Xh Y, with a normal female XH XH,

  • XH Xh, normal carrier female
  • XH Xh, normal carrier female
  • XH Y, normal male
  • XH Y, normal male

b) Both parents are normal and children still having hemophilia means that the mother is a carrier.

Let's see how it'll work out if we cross a normal male with a carrier female,

XH Y × XH Xh

  • XH XH, normal female
  • XH Xh, carrier female
  • XH Y, normal male
  • Xh Y, hemophiliac male

This means that the possibility of a female being normal, a carrier or not, is 100%. The possibility of a male being normal is 50% and the possibility of him being a hemophiliac is also 50%.

Thus it's possible that all 7 sons get hemophilia as each male baby has a 50% chance of having the genotype Xh Y. And it makes sense that all the females are normal. Those females could have the genotypes XH XH, or XH Xh (carriers).
