Plant with genotype AaBbCCDd produce how many types of gametes? A.16 B.8 C.32 D.4. pls explain?

Question

Answer

Formula for finding out types of gametes produced= '2^n'...
Where;
n= no. of heterozygosity...
Here; given is AaBbCCDd...
So; here n=3...
Therefore; no. of gametes =2^n=2^3=8....
So; option B is the answer...

Answer

Here is a trick
just consider 1 for homozygous and 2 for heterozygous and they multiply
eg AaBBCdDd
2×1×2×2 = 8
try this for your question

Answer

Possible answer:

Genetic recombination in gamete formation

When a diploid organism produces gametes, the two alleles of each gene segregate into different haploid cells, so that each gamete carries only one allele per gene. Furthermore, the assortment of different chromosomes during meiosis can generate new combinations of alleles that were not present in the parent's genome. This process of genetic recombination increases the genetic diversity of the offspring and provides the raw material for natural selection.

Calculating the number of gamete types

In the given genotype AaBbCCDd, there are four genes (A, B, C, and D) with two alleles each (A and a, B and b, C and C, and D and d). To determine how many types of gametes this plant can produce, we need to use the product rule of probability. This rule states that the probability of two independent events occurring together is the product of their individual probabilities. In this case, we can treat each gene as a separate event and multiply the number of possible alleles for each gene.

Thus, the number of different gamete types is:

2 (for gene A) x 2 (for gene B) x 1 (for gene C) x 2 (for gene D) = 8

Each gamete can have one of two alleles for genes A, B, and D, and only one allele for gene C, since both alleles are the same (C and C). Therefore, the total number of possible genotypes among the offspring of two such plants would be 8 x 8 = 64, assuming random mating and independent assortment of the genes.

Conclusion

A plant with genotype AaBbCCDd can produce eight different types of gametes, based on the principles of genetic recombination and probability. This knowledge can help predict the inheritance patterns and genetic variation in the offspring of such plants, as well as inform breeding strategies for desirable traits.
