The results for the F2 progeny are shown for a F1 cross using
the two X-linked markers:
w+ and m+.
As shown in the figure, the F1 cross is between the following
two parents:
- a phenotypically wild-type (red eye, full wing), heterozygous
female: w+m+/wm
- a double mutant male (white eye, miniature wing):
wm/Y
Answer the following questions:
1) In the F1 cross, can you infer the genotype for the phenotype
in the female? Why or why not?
2)...

An antigen found on red blood cells, Xg, is encoded by an
X-linked allele (Xa) that is dominant over an allele for the
absence of the antigen (X–). Scientists studied the inheritance of
these X-linked alleles in children with chromosome abnormalities to
determine where nondisjunction of the sex chromosomes occurred.
Match the genotypes of the parents and offspring to the parent
and cell division stage in which the nondisjunction must have
occurred. Shown as parent × parent = child.

6) A colorblind female, blood type A married 2 different men. One man (#1) had type AB blood and was colorblind. The other man (#2) had type B blood and normal color vision. Three offspring resulted from the marriages. If possible, determine the father of each of the following offspring. a) female, Type A blood, normal color vision b) male, Type AB blood, colorblind c) female, Type B blood, colorblind In tomatoes, red fruit color is dominant to yellow.

Human blood types A, B and O are associated with the carbohydrate antigens A, B and H respectively. A and B antigens are caused by an alteration of H antigen. Normally everyone can synthesize H antigen (a cell surface carbohydrate found on red blood cells and other cell types). Some people make A and/or B transferase(s) which converts the H antigen to an A and/or B antigen respectively. The H antigen is produced by a specific fucosyltransferase encoded by the...

Background INFO
There are four types of blood: A, B, AB, and O (Figure 4). Each
is characterized by the glycoproteins (proteins with a sugar
attached) and lipoproteins (proteins with a lipid attached)
embedded in the surface of red blood cells (RBCs). In addition to
type, blood can be rhesus (Rh) factor positive or negative.
These proteins are inherited and may differ from individual to
individual. If, during a transfusion, an individual receives
blood with the incorrect RBC proteins (for...
