Answer:
A) 50%
B) 25%
C) Same 25%
Explanation:
a) Smith parents should be heterozygous to the eye color gene, this means, they each should carry a copy of the “brown eye” gene (that we will call B), and one of the “blue eyed” one (that we will call b). Since the blue eye is a recessive trait, you can assume that they both inherited b genes to the daughter. If we draw a Punnet square (Bb vs Bb), we will see the possibilities of Smith having a copy of the blue eye gene (Bb), and it is 50%.
b) Again, with a Punnet square (Bb vs bb) we see that the possibility of having a blue eyed baby is 50% IF Smith carries the copy of the b gene. But since that possibility is established to be 50%, therefore the possibility of the baby to have blue eyes is reduced by half to 25%
c) The probability is the same, it does not have an additive effect, so there is no effect on the number of children
Vegetative reproduction is a mode of asexual reproduction naturally occurring in plants. In this process. only one of the parent is involved and the offspring is genetically identical to the parent and no sharing of DNA takes place.
Examples are: Onion, rhizome (ginger) and daffodil
Explanation:
There are meristem tissues found in the stem, root and leaves. These are undifferentiated cells and have tendency of dividing. This tissue gives rise to organs of the plant and responsible for its growth.
Natural vegetative propagation happens when an axillary bud grows into a lateral shoot and develops adventitious roots consequently forming a new plant.
Vegetative propagation can be done artificially also.
Answer: Too many deer in a given area results in overgrazing and the eventual loss of brush and shrubs in forested areas. Loss of undergrowth means no place for small animals and birds to shelter and nest. The result is the disappearance of many native species that no longer have access to the habitat they need.
