Evolutionary Novelties And Adaptations

Question 1

Answer 1

Species form while geographically isolated from its parents population

‘Allo parent, goodbye

Question 2

What is sympatric?

Answer 2

Speciation occurs without geographic separation

Sympatric = same place

Punching someone really fast then they dont move for ages

Question 5

What is hetrochrony?

Hint: development

Answer 5

Change in timing from zygote to maturity between two populations

Timing of particular genes being expressed DURING development

Hetro = different

Question 6

What does allometric growth mean?

Think metric maths

Answer 6

The proportion of phenotypic structure that change due to different growth rates IN RELATION TO THE ENTIRE ORGANISM

Metric of proportions and stuff

Question 7

What is a homeotic gene

Answer 7

It determines basic features that will be on the organisms

Eg where the leg is on a bird and the wings

Think homeotic basic features

Question 8

What is a hox gene

Answer 8

A homeotic gene that controls the body plan in the embryo

Think hox embryo
