dependent is the one being test
Answer:
All of their sons would be colour blind
Explanation:
Given that colour blindness is X linked recessive condition which means that the gene is located on X chromosome and when present in recessive homozygous condition, it will be expressed. Hence if XC is dominant allele and Xc is recessive allele, XcY and XcXc will be colourblind.
The male has normal vision and males have only one X chromosome so his genotype is XCY.
The female is colourblind and females have two X chromosomes so her genotype is XcXc.
Their children:
XC Y
Xc XCXc XcY
Xc XCXc XcY
All the sons have XcY genotype where gene for colourblindness is in recessive condition hence all of their sons would be colourblind.

As students observe several slides of tissue cross-sections, one simple key they can use to determine if the slides come from dicots or monocots is to analyze the <em><u>vascular bundles</u></em><em><u>.</u></em>
A vascular bundle is described as a portion of the transport system of vascular plants. These bundles are microscopically different in Monocots than they are in Dicots, which will allow students to tell them apart through the tissue slides.
The difference is that monocots contain <em><u>randomly scattered </u></em><em><u>bundles </u></em><em><u>located throughout the </u></em><em><u>stem</u></em><em><u>.</u></em> On the other hand, <u>dicots </u><em><u>have their vascular </u></em><em><u>bundles </u></em><em><u>more neatly organized in </u></em><em><u>concentric circles</u></em><em><u>.</u></em> These microscopic differences can serve as a key to be used by the students to classify the tissue samples they are studying.
