5. The phenotypic ratio is 9:3:3:1 where 9 combinations will produce offspring with both dominant phenotypes (dimples and brown hair), 3 will produce offspring with one dominant phenotype and one receive phenotype (dimples, blonde hair), 3 will produce offspring with one receive phenotype and one dominant phenotype (no dimples, brown hair), and one will produce offspring with both recessive phenotypes (no dimples, blonde hair)

sineoko [7]

Microarray data attached

Answer:

B, D, E are consistent with the data in the microarray

Explanation:

A) False, if you look at the microarray graph, Gene K is red on the right side of the graph (where patients in group II are) and generally more blue on the left side where group I patients are, meaning it is less expressed

B) This is true, look for example at gene F, individual 3 expresses it strongly, whereas individuals 6 and 7 are quite low.

C) No - microarray data looks at the expression of genes, not the genes themselves.

D) Yes, you can see that generally, genes B-Q are highly expressed in group II patients but not group I. In contrast, genes F-U are not expressed in group II but more expressed in group I.

E) Yes, although the data is not always consistent, there are clear patterns in group II patients not present in group I.

What is the special feature of an egg cell?
Arturiano [62]
The human egg cell is the largest cell in the human body, measuring approximately 0.13 mm in diameter. Its size is 10 times the diameter and 1000 times the volume of most other human body cells. It can actually be seen without the aid of a microscope if one observes keenly. Unlike ordinary body cells which have a cell membrane, the egg has a special outer coat called zona pellucida which is made up of a jelly-like extracellular matrix composed mainly of glycoproteins.
