Frogs undergo an external fertilization
process. Due to which eggs are fertilized outside the body of the frog. It lays hundreds of eggs which shows an external mode of reproduction. … So to maximise the survival rate, frogs create a lot of gametes.
Do frogs Have gametes?
Introduction – Some basic biology
Male frog gametes are sperm, and female frog gametes are eggs. Each gamete contains a single sex chromosome, chosen at random from one of the pair of adult sex chromosomes. Male frogs have an X-chromosome and a Y-chromosome, whilst female frogs have two X-chromosomes.
Is frog can reproduce large number?
Their mode of fertilization is external. They lay eggs in the water and there is a chance of destruction of these gametes by water current if they are in less quantity. So they lay more and more eggs in order to rule out the possibility of destruction of all eggs.
Who produces the greater number of gametes?
Females generally produce a few large gametes, while males typically produce astronomical numbers of tiny gametes. 2) Investment.
Why many frogs produce a lot of offspring?
Another reason behind this is there is a lot of organisms who feed on these eggs, so larger number of eggs gives more possibility of giving birth to young ones.

Why do frogs produce a large number of gametes at one time?
Frogs produce a huge number of gametes at one time – WHY do you think this is? Because they are too close to the bottom of the food chain, in order for the survival of the species,when they reproduce, they do so in the millions so only a few of the progeny will be bound survive sometimes.
How many offspring do frogs have?
After a female frog becomes mature, she can lay from two to more than 50,000 eggs at once, depending of species.
Do males produce more gametes than females?
Females generally produce a few but large gametes, whereas males produce large numbers of much smaller gametes. … Consequently, the limited number of gametes and the greater parental investment of the females result in an asymmetry in the degree of sexual selection between the two sexes.
Do females produce gametes?
Gametes are an organism’s reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome.
Where are gametes produced?
Gametogenesis. Gametes (germ cells) are produced in the gonads. In females, this is called oogenesis and, in males, spermatogenesis.
How many times do frogs reproduce?
Most frogs lay one to two clutches of eggs per year. Should a frog lay eggs two or more times per season, it will lay fewer eggs than it did the first time.
What animals that can reproduce in large number?
Insects are no slouches when it comes to reproduction and the African driver ant, which can produce 3 to 4 million eggs every 25 days, is thought to be the most generous of all.
How does the frog reproduce?
Typically, frogs lay eggs. This process usually occurs through external fertilization, where the female releases her eggs from her body into water. Then, the male releases his sperm to fertilize them. … Inside of the female fanged frog, the researchers found developed tadpoles rather than eggs.
Where are gametes produced in frogs?
Gametes are formed in specialized structures on the gametophyte called antheridia (containing male gametes) and archegonia (containing female gametes).
Can frogs reproduce asexually?
Key Concept: All animals reproduce their own kind. Reproduction is the process of making more of the same kind. Frogs reproduce sexually. That means that a male frog and a female frog must be involved.
Can frogs change gender?
Frogs can change their sex even in pristine, pollution free settings. Past research suggested that male-to-female sex changes happening in frogs in suburban ponds may be caused by increased levels of estrogen released into the water. … As far as they know, frogs can only change sex during their tadpole phase.
How many gametes do females produce?
One gamete comes from the female, and one comes from the male. Female gametes are also called eggs or ova. Female gametes are also called eggs or ova. They are created during the cellular reproduction process known as meiosis. The resulting gamete cell is a haploid cell.
How are female gametes created?
Gametes are formed through meiosis (reduction division), in which a germ cell undergoes two fissions, resulting in the production of four gametes. During fertilization, male and female gametes fuse, producing a diploid (i.e., containing paired chromosomes) zygote.
What is the production of female gametes called?
A gamete is a reproductive cell or sex cell that contains the haploid set of chromosomes. It is produced through a germ cell that undergoes gametogenesis, a process of gamete formation involving meiosis. The gametogenesis that leads to the production of the female gamete is called oogenesis.
Why do females produce fewer gametes than males?
Although asymmetry in gamete size rather than number is usually used as the defining characteristic, size dimorphism has the almost inevitable consequence that females pro- duce fewer gametes than males due to a simple physical trade-off – larger things can be produced in smaller numbers, given a limited amount of …
How is gamete production different in males and females?
The main difference between male and female gametes is that male gametes are called sperm cells and are produced by the male reproductive organs whereas female gametes are called egg cells and are produced by the female reproductive organs. Both male and female gametes are produced by meiosis of the germ cells.
How many eggs do tree frogs lay?
Most of the species lay eggs – an average clutch consists of about 50 eggs, but some species lay up to 4,000 eggs.
How long are frogs pregnant?
Frogs eggs hatch anywhere from three to 25 days after they are laid.
