What is the
difference between a hen and a human
in respect of internal fertilization?
​

What is the basic difference between reproduction mechanism in human being and hen? Ans: Human being gives birth to baby, they are viviparous; whereas Hen lays egg and they are oviparous. Q15: Why do frogs and fish lay eggs in hundred, whereas a hen lays only one egg at a time

SIMILARITIES:

Both the chicken and the human need a sperm and ovum to produce an infant or egg

The ovum needs to be fertilized before it becomes an embryo

Fertilization needs to occur inside the body of a chicken or human

DIFFERENCES:

Chickens produce an egg and the chick hatches outside the body, while humans carry the embryo inside the female's body and the infant hatches from the embryo inside the body

Roosters do not have a penis, but the male human does

Chickens lay more than 1 egg, while humans can only produce 1 baby at a time

Chickens do not have breasts and therefore do not feed milk to their young, but female humans do and breastfeed their young at birth

Humans carry the embryo for over 9 months, but chickens' eggs only take around 21 days to hatch

Human's unfertilized ovum becomes menstruation, but chickens lay their egg even though it's unfertilized
