Topic 3: Genetics

Question 1

list Mendel’s Laws

Answer 1

1. Law of Segregation
2. Law of Independent Assortment
3. Principal of Dominance

Question 2

outline the Law of Segregation

Answer 2

when gametes form, the alleles separate during meiosis so that there is one allele for each gene in a gamete

Question 3

outline the Law of Independent Assortment

Answer 3

separation of alleles for one gene occur independently from any other gene

Question 4

outline the Principal of Dominance

Answer 4

recessive alleles will always be masked by dominant alleles

Question 5

what is a gamete

Answer 5

haploid sex cells formed during meiosis, contain only one copy from an allele of a gene

Question 6

what is a male haploid

Answer 6

sperm

Question 7

what is a female haploid

Answer 7

ova

Question 8

haploid + haploid = ?

Answer 8

zygote

Question 9

when the maternal and paternal allele are the same, it is…?

Answer 9

homozygous

Question 10

when the maternal and paternal allele are not the same, it is…?

Answer 10

heterozygous

Question 11

define genotype

Answer 11

combination of alleles for a specific trait

Question 12

define phenotype

Answer 12

observable characteristics from that trait
