H- for that gene

Answer 2

Homozygous

Question 3

Different allele equals?

H- for that gene

Answer 3

Heterozygous

Question 4

What is Autosomes?

Same a- and n- in males and females

Answer 4

appearance

number

Question 5

What Pedigree analysis?

Useful for tracing g- and traits across g-

Answer 5

genes

traits

Question 6

Difference between animal & plant cells in mitosis

Answer 6

In animals Cleavage furrow forms between the two nuclei

In plants Cell plate forms between the two nuclei

Question 7

Genetic conseqences of Meiosis?

Lack c- and c-

Cell wall means ‘animal-like’ c- is not possible

Answer 7

centrosomes

centrioles

Question 8

Prophase?

Answer 8

is the first phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells

Question 9

What are the different stages of mitosis?

P-
Pro- 
M- 
A- 
C-/T-

Answer 9

Prophase 
Prometaphase
Metaphase 
Anaphase 
Cytokinesis/Telophase

Question 10

Prometaphase?

Answer 10

The nuclear membrane breaks down and allows the spindle fibres to attach to the kinetochore of each chromosome at the centromere

Question 11

Metaphase?

Answer 11

is the third phase of mitosis, the process that separates duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells

Question 12

Anaphase?

Answer 12

when replicated chromosomes are split and the newly-copied chromosomes

Question 13

Telophase?

Answer 13

the sister chromatids reach opposite poles. The small nuclear vesicles in the cell begin to re-form around the group of chromosomes at each end.

Question 14

Cytokinesis?

Answer 14

is the physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells

Question 15

Genes?

Are d- h- factors that determine t-

Answer 15

discrete
hereditary
traits

Question 16

Genotype?

is the g- make up of an o-

Answer 16

genetic

organism

Question 17

Phenotype?

Is the set of detectable c- or traits of an o-

Answer 17

characteristics

organism

Question 18

Dominant?

refers to the appearance of one of the two possible p- associated with two alleles in a h-

Answer 18

phenotypes

heterozygous

Question 19

Recessive?

Where a- for a single g- are different in the one individual

Answer 19

alleles

gene
