How many types of gametes are produced by two genes AaBb showing linkage?

What is the probability that parents AaBb and AaBb will have offspring with genotype AaBb?

The correct answer: The probability of an aabb offspring when AaBb x AaBb parents are crossed is b. 1/16 .

What are the types of gametes that can be produced by an individual with the genotype AaBbCc?

The plant having genotype AABbCC is heterozygous for only one character B. Number of “gametes = 2n”, where n is the heterozygosity.” Since n = 1 so 2 gametes will be formed. Those are ABC and AbC. So the two types of gametes will be ABC and AbC.

How many types of gametes are produced by genotype AaBbCc if all genes are linked?

IT IS INTERESTING:  Are mycelia haploid or diploid?
No. of homologous chromosome pairs (heterozygous genes) No. of different gametes from each parent
3 (AaBbCc X AaBbCc) 8 (23)
4 (AaBbCcDd X AaBbCcDd) 16 (24)
20 pairs of chromosomes 1,048,576 (220)
23 pairs of chromosomes 8,388,608 (223)

How many different types of gametes would be produced by an organism of genotype AaBbCcDdEe if all of the genes assort independently?

The number of different possible gametes produced by the diploid genotype (AaBbCcDdEe) is 2 x 2 x 2 x 2 x 2 = 32 (2 for each pair of heterozygous genes).

How many types of gametes are 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.

What will be the frequency of AaBb individuals from mating of two AaBb individuals?

1 : 1 : 1 : 1.

How many kinds of gametes can be produced by an individual of genotype?

Complete answer:

Here, the given genotype consists of two heterogeneous alleles Bb, and Cc while one homozygous allele is AA. So, it results in the production of 22= 4 types of gametes. These types of genotypes that are ABC, ABc, AbC, and Abc will be found in the gametes.

What type of gametes will be formed by genotype RrYy?

A plant with genotype RrYy, produce four types of gametes during fertilization. They are RY, Ry, rY, ry. So, the correct option is ‘four’.

How many types of gametes can be produced by a diploid organism who is heterozygous for 4 loci?

n = 4, therefore the number of gametes produced are 2n = 24 = 16 types. Therefore a diploid organism is heterozygous for 4 loci produces 16 different types of gametes.
