I think the correct answer from the choices listed above is option B. If pink snapdragons of the F1 hybrids (RW) are crossed with red snapdragons of the parent plant (RR), the ratio of flowers produced in 40 offspring would be <span>20 pink flowers, 20 red flowers. This can be proved in by making a Punnett Square.</span>
The percentage of offspring with particular genotype and phenotype can be determined using the
Punnett squares as shown in image.
The crossing between the F1 hybrid pink flower and parent red flower produces 50% of each red and pink type of flowers. Therefore, for 40 offspring, 50% each i.e. 20 red and 20 pink flowers will be produced.
Therefore, the correct answer is B.) 20 pink flowers, 20 red flowers.
It has been suggested that these kinds of lesions may be indicative of fighting with other members of its species or the attacks of predators
Explanation:
The Neandertals were exposed to very hard environmental conditions, thereby these lesions may be indicative of such conditions to which this species was exposed.
