Medellian Genetics

Question 1

why are alleles important to genetics

Answer 1

they decide our genotype

Question 2

how do alleles pass traits to offspring

Answer 2

by giving the offspring one inherited trait from each parent

Question 3

what is the difference between dominant and recessive alleles

Answer 3

dominant: it is always seen in the organism
recessive: it is not seen, dominant takes over recessive

Question 4

what is the difference between mitosis and meiosis

Answer 4

mitosis: the replication of body cells
meiosis: when the sex cells divide

Question 5

what are punnett squares

Answer 5

determines the possibility of inheriting any trait

Question 6

what is the difference between genotype and phenotype

Answer 6

genotype: exactly the genes that were inherited
phenotype: physical appearance and expression of the gene

Question 7

what are the three genotypes?

Answer 7

homozygous dominant (DD) homozygous recessive (dd) and heterozygous (Dd)

Question 8

what is the difference between haploid and diploid number

Answer 8

haploid number is 23, diploid number is 46

Question 9

what is the difference between incomplete dominance and codominance

Answer 9

incomplete dominance: the offspring do not inherit the traits of either parent
codominance: the offspring exhibit the traits of both parents

Question 10

what is heredity

Answer 10

process through which traits are passed on from one generation to another

Question 11

what is a trait

Answer 11

any visible or invisible characteristic, function, or process that is a necessary part of an organism

Question 12

what is a gene

Answer 12

structure thay contains the code for every trait

Question 13

Answer 13

particular form of a trait
