Name 2 difference between RNA and DNA What happens is there is no interphase in mitosis?
What is the ploidy of the daughter cells in mitosis? Where does fertilization take place? What is
the ploidy of a gamete? What is a fertilized egg called? Can a pregnant woman have a normal
cycle? What is Gregor Mendel\'s Law of Segregation? What is Mendel\'s Law of Independent
Assortment? What is Gregor. Mendel\'s Law of Dominance?
Solution
9.(a)RNA is single stranded while DNA is double stranded.
(b)RNA comprises of a Ribose sugar whereas DNA comprises of Deoxyribose sugar.
10.Interphase and mitosis are 2 different events,but they are connected in some way.If there is no
interphase, will lead to no DNA replacation,no organelle replication, and thus no mitosis.
12.In humans,fertilisation takes place in fallopian tubes,which is near to ovary.
13.Human diploid cells and haploid gametes have 46 and 23 chromosomes respectively.
14. A fertlised egg is called zygote.
15.No,menstruation cycle will not produce any bleeding at time of pregnancy.
16.When sperm and egg unite at fertilization, each contributes its allele, restoring the paired
condition in the offspring. This is called the Law of Segregation. Mendel also found that each
pair of alleles segregates independently of the other pairs of alleles during gamete formation.
17.Law of independent assortment states that when two or more characteristics are inherited,
individual hereditary factors assort independently during gamete production, giving different
traits an equal opportunity of occurring together.
18. Mendel\'s third law (also called the law of dominance) states that one of the factors for a pair
of inherited traits will be dominant and the other recessive, unless both factors are recessive.
