Unit 6: How do characteristics pass from one generation to another?

Question 1

Law of segregation

Answer 1

law states that individuals have two alleles for a trait, but only pass one allele on to their offspring. A gamete will either have a dominant or recessive allele, but not both

Question 2

Law of independent assortment

Answer 2

the inheritance of one pair of genes is independent of the inheritance of another pair. This means that alleles from different genes are sorted into gametes independently.

Question 3

Law of dominance

Answer 3

when parents with contrasting traits are crossed, only one trait will appear in the next generation.

Question 4

What is transcription

Answer 4

The process of copying a segment of DNA into RNA

Question 5

Answer 5

1. RNA is single stranded molecule, DNA is double.
2. RNA has ribose which has one more oxygen atom than deoxyribose.
3. RNA has Uracil instead of Thymine - 4th nucelotide.
