Let's assume that the ability to cross one's eyes is a mendelian trait, in that it is determined by only two alleles, which can be dominant, recessive, or a combination of the two. eye crossing is the dominant trait and the inability to cross one's eyes is the recessive trait. (this is a completely imaginary scenario.) a man marries a woman and they have a child together. the father is heterozygous dominant for the trait of eye-crossing, and the mother is homozygous recessive for the trait. what are the chances that their child will be born with the ability to cross his or her eyes?

The endoplasmic reticulum (er) is an organelle in some cells. in these cells, it is continuous with the nuclear membrane and forms a large part of the cell\'s total membrane. sort the phrases below as describing rough er, smooth er, both, or neither. note: if you answer any part of this question incorrectly, a single red x will appear indicating that one or more of the phrases are sorted incorrectly.1) found in prokaryites and uekaryotys2) involved in protein synthesis3) involve in lipid synthesis4) contains molecular chaperones in lumen5) bound with ribosomes6) involved in toxin or drug metabolism7) large systemot internnected tubules,vesicles, and sacs8) "packages" enzymes in vesicles for secretion.

Use this new information to determine the parents’ genotypes (indicated by red arrows). then calculate the probabilities that the second male offspring will have each condition. drag one pink label to each pink target and one blue label to each blue target. then use the white labels to answer questions 1 and 2. labels can be used once, more than once, or not at all.
