Humans have 23 pairs of chromosomes. That means that one person could produce 223 different gametes. In addition, when you calculate the possible combinations that emerge from the pairing of an egg and a sperm, the result is (223)2 possible combinations.
How many gametes can be found through genotype?
No.of possible gametes can be found through genotype by counting the no.of heterozygous (dissimilar) allele pairs present in the genotype,denoted by 'n'. No of possible genotypes = 2^n ( 2 raised to the power n).
How many gametes does the AABB genotype have?
Therefore AAbb genotype has only one gamete and that is Ab. AAbb represents the genotype for the alleles of two genes in a diploid state. Gametes are haploid and will have one of each allele for each gene: Ab. This question is a little mangled, but I’m assuming what you’re asking is something like the following:
How are gametes produced in flowering plants?
In flowering plants the flowers use meiosis to produce a haploid generation which produce gametes through mitosis. The female haploid is called the ovule and is produced by the ovary of the flower. When mature the haploid ovule produces the female gamete which are ready for fertilization. The male haploid is pollen and is produced by the anther,...
What is the difference between egg and sperm and gamete?
The egg and the sperm are the gametes. Now the second part, the letters you used are used as a denotation for genes on the chromosome. Each gamete would have 1 set of theses genes; the egg might be ABDeF, and the sperm might be AbDef. When the egg and and sperm fuse, the resulting cell would be AABbDDeeFf.
How many different gametes were produced?
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.
How many genetically different gametes are possible for AaBb?
four possible combinationsThere are four possible combinations of gametes for the AaBb parent. Half of the gametes get a dominant A and a dominant B allele; the other half of the gametes get a recessive a and a recessive b allele. Both parents produce 25% each of AB, Ab, aB, and ab. (Review problem #3's tutorial if necessary).
How many types of gametes can be produced by YyRr?
After fertilisation, the F1 heterozygote will be formed i.e YyRr (yellow and round). On selfing F1 we get two possible combinations i.e YR, Yr, yR, yr. Therefore four types of gametes are formed in the ratio of 1:1:1:1. Thus, the correct answer is option D.
What is the probability of producing an AaBb gamete from the genotype AaBb?
For genotype AaBB, the probability of generating an AB gamete is 1/2. For genotype AABb, the probability of generating an AB gamete is 1/2. Again, because both genotypes have equal probabilities, the final probability of the parent generating an AB gamete is (1/2) × (1/2) + (1/2) × (1/2) = 2/4 = 0.5 = 50%.
How many types of gametes would be produced of the genotype of a parent is AaBB * A 1 B 2 C 3 D 4?
If the genotype of a parent is AaBB then 2 types of gametes will be produced.
How many different gametes can be made by an individual with the genotype AaBB quizlet?
An individual with the genotype AaBb produces four different gametes in equal proportions.
How many possible gametes are there with genotype AABbCC?
Explanation: A plant having genotype AABbCC will produce only two types of gametes, ABC and AbC.
