<h3>What is phenotype?</h3>
Phenotype is referred to as the expressed trait that is caused by a certain combination of alleles. We will recall that the HbS allele is responsioble for the anemia that results from sickle shaped red blood cells.
This phenotype is both harmfull and benefical in the sense that it leads to the agglutination of the red blood cells in individuals that have this phenotype and eventual crisis. Also, it is beneficaila in that nthose who possess this phenotype do not suffer from malaria in the tropics.

The correct answer is d. "Regeneration" means "forming new cells," and signifies that the disease-causing bacteria cells are multiplying. When there are more of these cells, there is a higher chance for antibiotic resistance (making it take longer for the antibiotics to work). Once there is a smaller concentration of these bacterial cells, the antibiotics become more effective.
Answer:
Answer is option D.
Flowers contain parts for making seeds.
Explanation:
The part of the plant that is responsible for the sexual reproduction in plants is known as flowers. A flower is said to be complete if contains sepals, petals, stamens and pistil. If the flower lacks one or more structures, it is an incomplete flower.
A complete flower consists of a vegetative part and a reproductive part. The vegetative part contains petals (a bright coloured structure that attracts insects and birds) and sepals (a green coloured structure that protects rising buds and is usually found beneath the petals). The reproductive parts include stamen or androecium (male reproductive organ) and pistil (female reproductive organ). A flower may consists of only female parts or only male parts, or both.
Stamen contains two parts - anther, which produce and store the pollens (male gametes) and filament, which support the anther. Pistil contains three parts - stigma, which receives the pollen grains and style that connects stigma and the ovary, and ovary which contains a lot of ovules (female gametes) which forms the seed.
Flowers reproduce by pollination, a process in which the pollen are transferred to the stigma of another flower. A pollen tube emerges from the pollen grain and grows through the style and reaches an ovule inside the ovary. Then the nucleus of the pollen grain passes through the pollen tube and fuses with the nucleus of the ovule and this process is known as fertilisation. The fertilised ovules become seeds and the ovary transforms into the fruit. The seeds are dispersed through various methods and the embryo inside them will grow into adult plants.

White flowers are recessive, so there is a 1/4 chance
And when crossing alleles for shape you get
25% rr
50% Rr
25% RR
Wrinkled seeds are recessive so there is a 1/4 chance
Since you are looking for white flowers AND wrinkled seeds, you need to multiply 1/4 x 1/4, giving you a 1/16 chance that the offspring will have these two traits
