Variation And Inheritance

Question 1

Why are predicted phenotype ratios amount offspring not always achieved

Answer 1

Because FERTILISATION IS A RANDOM PROCESS

Question 2

What does heterozygous

Answer 2

Two alleles that’s are different

Question 3

What is homozygous

Answer 3

Two alleles combination what are the same

Question 4

What is continious variation

Answer 4

Distinct variation is when several different genes influence a characteristic. CONTINUOUS VARIATION CAN BE DISPLAYED AS A HISTOGRAM when the curve is drawn it should be bell shaped if so then it is a normal distribution curve

Question 5

What is discrete variation

Answer 5

This is variation where a single gene inheritance of a characteristic shows discrete variation where measurements fall into distinct groups THIS INFORMATION CAN BE STORED IN A BAR GRAPH

Question 6

What are ALLELES

Answer 6

the form/type of a particular gene inherited from parents that might be the same or different

THE DIFFERENT FORMES OF THE SAME GENE ARE KNOWS AS ALLELES (for example eye colour is an allele

Question 7

What is a genotype

Answer 7

the set of genes (alleles) possessed by an individual

Question 8

What is a phenotype

Answer 8

The physical characteristics of an organism

Question 9

F1
F2

Stand for

Answer 9

P: parents generation

F: First generation

F2: second generation
