Question

Please help with #1 I attempted to answer #2 and #3 but want to double check these are correct

1.) Homeotic genes in virtually all animals are said to show colinearity between the spatial arrangement of the tissues on which they act and with what other feature?

a. gene location

b. high degree of conservation

c. number of paralogs

d. early expression

2.) Ubx and Hoxa6 are orthologs

True

False i put false but need to make sure this is correct

3.) Maternal effect genes are transcribed in the egg after fertilization.

True

False - i put false but need to make sure this is correct

Explanation / Answer

The Hox genes show high degree of conservatoin of their nucleotide sequences and function. Though in genomes functional elements evolve at slower rate than non-functional elements, the high level of conservation of Hox gene sequences and functions help scientist to compare among closely related organisms. Therefore, the correct answer is

b) high degree of conservation
