Mission

We must stop the factory to prevent them from continuing to produce medicines that cause negative effects on humans.

In peas, yellow seed colour (A) is dominant over green seed colour (a). If we cross two plants that are heterozygous (Aa) for this trait, what will be the probability that their offspring will have green seeds?

The probability of obtaining green seeds is 25%, since only the "aa" genotype produces green seeds in the offspring.

The probability of obtaining green seeds is 50%, since only one of the two alleles needs to be "a" to produce green seeds.

Question 1/3

In a flower species, the color red (R) is dominant over the color white (r). If we cross a homozygous plant with red flowers (RR) with a plant with white flowers (rr), what color will the flowers of the offspring have?

All the flowers will be red, since when crossing RR with rr, all the offspring will be heterozygous (Rr) and will present the dominant color.

The flowers of the offspring will be white and red in equal proportions.

Question 2/3

In intermediate inheritance, a cross between two organisms with different phenotypes produces offspring with an intermediate phenotype. In a plant, the flower color can be red (RR), white (BB), or pink (RB) due to intermediate inheritance. If we cross two plants with pink flowers (RB), what percentage of the offspring will have pink flowers?

100% of the offspring will have pink flowers, as both parents have pink flowers.

50% of the offspring will have pink flowers, since when crossing RB x RB, the possible genotypes are RR (red), RB (pink) and BB (white), resulting in a 1:2:1 ratio.
