The probability of progenies to have red flower is 50%.
<h3><u>Explanation:</u></h3>
The phenomenon where the two pure alleles of a particular character present in an individual gives a mixed appearance is called incomplete dominance, where the dominant character cannot fully mask the presence of a recessive character.
Here In the cross between a red flowering plant and the pink flowering plant, the character shows the incomplete dominance.
Let the allele for dominant character i.e red flower be R and recessive character white be r.
So the genotype for red flowering plant = RR.
The genotype for pink flowering plant =Rr.
The gametes from red flowering plant =R.
The gametes from pink flowering plant =R and r.
So with the cross, the genotype of the offsprings will be 50% RR and 50% Rr.
So plants with red flowers will be 50% of the whole progeny.
The answer is growth and development.
Answer:
Algae are classified based on the
1. type of chlorophyll and secondary pigments
2. method of food storage
3. composition of cell wall
Explanation:
Algae can be classified on the basis of chlorophyll or other secondary pigments. For example, green algae have chlorophyll a and b. Brown algae possess chlorophyll a, c, carotenoids and xanthophyll pigments. Red algae possess a red pigment called r-phycoerythrin.
Other characteristics on which algae can be classified are their mode for storing food and the composition of the cell wall.
When a Stickleback fish feels threatened, it will flare out its pair of pelvic spines and three dorsal spines, making it difficult for predators to swallow them.
