Solution

The correct answer is figure (2) is one point crossover of figure (1)

Explanation:

The image contains a genetics problem about crossover in offspring. It shows two parents and their possible offspring. Crossover is a genetic mechanism where chromosomes swap genetic material during meiosis (sexual reproduction) in eukaryotes.  Here's how to solve the problem:

1. Identify the parents' genotypes:

• Parent 1: 10110 (with crossover points) 010
• Parent 2: 10101 (with crossover points) 111

2. Analyze the offspring (Figure 2):

• The offspring has the following genotype: 10110  111
• The offspring has the following genotype: 10101  010

3. Identify the type of crossover:

In a one-point crossover, a single crossover point is chosen along the chromosome, and the parental chromosomes exchange genetic material beyond that point. This is what we see in the image where the offspring inherits the first two genes from parent 1 and the last three genes from parent 2.

Looking at the parents and the offspring, we can see that there's a single crossover point between the second and third genes. This eliminates options (3) N point crossover and (4) uniform crossover, which involve multiple crossover points or probabilistic crossover throughout the chromosome. Option (1) two point crossover is also not possible because a two-point crossover would have two crossover points.

Therefore, the answer is (2) one point crossover of figure (1).
