Hence, 8 gametes are formed by the diploid organism.
How many types of gametes can be produced by a diploid organism if it is heterozygous for 3 loci?
Types of gametes =2n where n is number of heterozygous loci. Thus, gametes produced by a diploid organism could be 24=16.
How many types of gametes can be produced by a diploid organism if it is heterozygous?
For example Aa, Bb, Cc, Dd obtained during the meiosis and segregated into the 8 different gametes and also known by the type heterozygous. But diploid organisms will produce 16 different gametes if the genes are not linked.
How many different types of gametes can a plant produce if it is heterozygous for two traits?
So the correct option is ‘four‘.
How many types of gametes can be produced by?
The number of gametes produced by a specific genotype is calculated by the formula 2n, where n= number of heterogeneous alleles present in the genotype. Here, the given genotype consists of two heterogeneous alleles Aa and Bb while CC is homozygous. So, it can produce 22 = 4 types of gametes.
Why is test cross done?
A test cross is performed in order to determine the genotype of a dominant parent, i.e., whether it is a heterozygous or a homozygous dominant. On the basis of the results obtained, the ratios of the offsprings help us to predict that the parent has which type of genotype.
What is loci in biology?
A locus is the specific physical location of a gene or other DNA sequence on a chromosome, like a genetic street address. The plural of locus is “loci”.
How can alleles be different?
When the copies of a gene differ from each other, they are known as alleles. … Alleles can sometimes result in different phenotypes (observable traits), with certain alleles being dominant (overriding the traits of other alleles) or, in some cases, multiple alleles acting in a codominant fashion.
Which of the following types of gametes will not be produced by the plant with the genotype Aabbccdd?
Answer: AaBbCC will produce 4 types of gametes which are as follows- ABC, AbC, aBC, abC. The number of gametes formed is decided by the number of heterozygous alleles present in the given genotype. … Say for example, in the above genotype Aa & Bb are the 2 heterozygous alleles, so here n=2.
