Question 5

Natural Selection

Answer 5

The process of reproductive success based on favored traits and disfavored traits

Question 6

Adaptation

Answer 6

A trait that becomes more common in a population through natural selection for its improvement on fitness in current environment

Question 7

Mendelian Genetics

Answer 7

Idk DNA genetics passed down from parents or something

Question 8

Phenotypes

Answer 8

observable traits

Question 9

Genotypes

Answer 9

Genetic makeup that we cant see made of alleles

Question 10

Chromosomes

Answer 10

Strands of DNA, humans have 23 pairs of them

Question 11

Homozygous

Answer 11

an organism has two identical alleles, YY, yy

Heterozygous

Answer 12

An organism has two different alleles, Yy

Question 13

Dominant allele

Answer 13

The allele that will always overshadow the recessive allele

Question 14

Recessive allele

Answer 14

the Allele that is usually less likely to be the outcome or overshadowed by dominant

Question 15

Mendelian Trait

Answer 15

A trait that is determined by a single gene “simple”

Question 16

Polygenic Trait

Answer 16

A trait who is influenced by more than one gene

Question 17

Incomplete Dominance

Answer 17

Basically when to genes mix, ex - Straight or Curly hair… Wavy

Co-Dominance

Answer 18

Basically when two dominant alleles are represented, ex - Black or white feathers… white feathers with black specks

Principle of Segregation

Answer 19

The process where is a pair of chromosome splits apart for reproductive DNA

Question 20

Heritable

Answer 20

Traits that are able to be passed down

Question 21

Mutations

Answer 21

Random change in a gene or chromosome which may create a new trait

All of the genetic material within a population

Question 23

Deme

Answer 23

The part of the population that breeds

Question 24

Species

Answer 24

Defined by the ability to breed and produce viable offspring or “reproductive isolation”

Question 25

Temporal Isolation

Answer 25

time when organism cant be together like hibernation

Behavioral Isolation

Answer 26

cant mate because of migration

Question 27

Mechanical Isolation

Answer 27

Answer 31

Selection for both extremes of the phenotypic Distribution

Sexual Selection

Answer 32

Non-random mating when an organism choose particular mate
