Answer:
3 yellow : 1 green
Explanation:
Yellow seed allele (Y) is dominant over the green seed allele (y).
A cross between two true breeding parents is done: YY x yy
The F1 offspring would be heterozygous Yy.
<u>If the F1 is selfed (Yy x Yy) the expected ratios for the F2 generation according to Mendel's law of segregation would be:</u>
- 1/4 YY (yellow)
- 2/4 Yy (yellow)
- 1/4 yy (green)
So 3/4 seeds of the F2 would be yellow because they have a dominant Y allele, and 1/4 would be green.
The phenotypic ratio will be 3 yellow : 1 green
Answer:
the correct oprtion is B
Explanation:
the correct answer is b, since increasing the porosity of the contact lens allows it to work as a good method of gas exchange, simulating the lung membranes that present fenestrated capillaries that promote gas exchange. For this to happen, the permeability must always be high and therefore this is directly related to the porosity of the element with which the contact lens is made.
