In humans, the allele for red-green color blindness is x-linked and recessive (xr; the dominant allele is called xr). a man with normal color vision marries a color-blind woman who gives birth to a color-blind daughter. what can be inferred from this information?

It concludes that the man is not the real father of the girl child.

Explanation:

Sex-linked or the X linked characters are the traits that inherited in a change or mutation in X chromosomes that cause the phenotype change in the male, which are homozygous for the gene as only possess one X chromosome and one Y chromosome, and Females if they are homozygous for the gene.

In the question, Man has a normal color vision (XrY) that means he has no mutated allele of color blindness. female has color blindness so that means she is a homozygous chromosome for the gene. Cross between these two results in 50% carrier daughters (XrXR) and 50% color blindness son (XRY). It means there is no chance for the color blind daughter.

Thus, the correct answer would be the man is not the real father of the girl child.

emerald ash borer

the emerald ash borer is a green buprestid or jewel beetle native to north-eastern asia that feeds on ash species. females lay eggs in bark crevices on ash trees, and larvae feed underneath the bark of ash trees to emerge as adults in one to two years. hope this !

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
