The two most common gametes are sperm and ova. These two haploid cells can undergo internal or external fertilization and can differ from each other in size, form, and function. Some species produce both sperm and ova within the same organism.
What type of gamete will be produced?
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. These reproductive cells are produced through a type of cell division called meiosis.
How many different types of gametes can a human produce?
We have 23 pairs each with 50/50 probabilities. That works out to 223 possible combinations of gametes from one human individual.
What are the 4 gametes?
The gametes in animals are sperm (male) and eggs (female). The gametes in flowering plants are pollen (male) and ovules (female). The offspring produced in sexual reproduction are genetically different to each other and to their parents.
When F1 plant undergoes meiosis what gamete types will it produce?
Explanation: When an F1 plant undergoes meiosis, the gametes will be 1/2 Y and 1/2 y. When a homozygous yellow line (YY) cross with a homozygous green line (yy), it will result in F1 plants that are heterozygous (Yy) for the same trait and yellow seeds will be produced.
How many gametes can be produced from AaBbCc?
Hints For Biology 101 Exam #4
|No. of homologous chromosome pairs (heterozygous genes)||No. of different gametes from each parent|
|1 (Aa X Aa)||2 (21)|
|2 (AaBb X AaBb)||4 (22)|
|3 (AaBbCc X AaBbCc)||8 (23)|
|4 (AaBbCcDd X AaBbCcDd)||16 (24)|
What gametes would be produced by AA?
An individual with the genotype Aa can make two types of gametes: A and a. Since this is a random process, the individual will, on average, make equal numbers of each gamete. (Frequency of 1/2 for each gamete). A second individual with genotype Aa can make two types of gametes: A and a.
Do gametes determine gender?
Sperm cells carry either an X or Y sex chromosome. Female gametes, or eggs, however, contain only the X sex chromosome and are homogametic. The sperm cell determines the sex of an individual in this case. If a sperm cell containing an X chromosome fertilizes an egg, the resulting zygote will be XX, or female.
Can humans produce both gametes?
Women don’t produce sperm because they do not have the Y chromosome, which possess a gene that tells the body to produce male features. Humans, like all mammals, have two separate sexes. … If animals have the necessary genes to produce either of the gametes, they could produce both.
Are gametes alive?
Paulson points out, both the sperm cell and egg cell are living cells, as is the zygote formed from the fusion of the sperm and the egg. So the science tells us that as far as when the zygote is considered “living,” it is a living cell from the beginning.
Where will the male and female gametes be just before fertilization?
Male gametes are found inside tiny pollen grains on the anthers of flowers. Female gametes are found in the ovules of a flower.
