Answer:
it’s more likely due the brown alele is dominant.
But it depends on the genotype, because she can be a carrier of the blue gene. In the simplest models of eye color, there are two genes involed (this is a simplified model).
Gene 1 there are two possibilities brown or blue. The brown version of the gene 1 is dominant over the blue one. Dominant means is if a least 1 of your copies is brown. then you will have brown eyes.
Gene 2. there are two possibilities, green or blue. Green is dominant over blue,
The high turgor pressure drives movement of phloem sap by “bulk flow” from source to sink, where the sugars are rapidly removed from the phloem at the sink. Removal of the sugar increases the Ψs, which causes water to leave the phloem and return to the xylem, decreasing up

because the dry climate is warm
Option D is correct.
A synapse is the opening between neurons that neurotransmitters pass through.
Answer:
9:3:3:1
Explanation:
This type of crossing that involves two characters is referred to as dihybrid crossing. Generally, when there is a dihybrid crossing for heterozygous genes for both parents, the phenotypic ratio is usually 9:3:3:1 as shown in the figure in the attached document below.
Assuming the colour is White (P) and Black (p) and the
Height is Tall (T) and short (t)
The possible phenotypes will be in the ration
9 - White and Tall
3 - White and short
3 - Black and Tall
1 - Black and short
It should be noted that phenotypic ratio (phenotype) describes the outward appearance (what can be see physically) and not the genetic make-up. Thus, where there is a dominant character like P or T, the recessive characters are not considered to have been expressed.
