Suppose that a dominant allele (P) codes for a polka-dot tail and a recessive allele (p) codes for a solid colored tail. In addition, suppose that a dominant allele (L) codes for long eyelashes and a recessive allele (l) codes for short eyelashes. If two individuals heterozygous for both traits (tail color and eyelash length) mate, the probability of the phenotypic combinations of the offspring will be in the ratio, D. 9:3:3:1 ratio (9 polka-dot tails and long eyelashes, 3 polka-dot tails and short eyelashes, 3 solid tails and long eyelashes, 1 solid tail and short eyelash).
The solution is found by solving a Punnett square shown in the image.

Explanation:
<em>The concluding part of the question can be seen in the attached image.</em>
The correct answer would be that <u>the father did not contribute a sex chromosome to his daughter due to nondisjunction of the sex chromosome. The daughter is XO and her only X chromosome came from the mother who is a carrier.</u>
Since the mother's maternal grandfather had the syndrome and there is no history of it in the father's family, the daughter must have inherited an affected chromosome from her carrier mother. Normal females have two X chromosomes - one from each parent - and would therefore require two affected chromosomes in order for X-linked diseases to manifest in them.
<em>In this case, the syndrome manifested in the daughter because she lacks one X chromosome - a situation caused by a missing X chromosome in the father. Hence, the daughter is XO instead of XX and the single chromosome is an affected chromosome from the carrier mother. </em>
Answer:
Explanation:
This is Xylose-glucose which is an Organic sugar - first isolated from <em>wood</em> ( xylose in greek, which it is named after ), and is a monosaccharide free within the aldehyde group. This is a reducing sugar.
You may know that oxygen, carbon, and hydrogen and base organic elements found in pretty much all organic substances.
