Answer:

Answer:Monohybrid Cross

Answer:Monohybrid CrossIn a monohybrid cross, the parent organisms differ in a single characteristic. Suppose, for example, two humans have children. The father has a widow's peak and the mother does not. A widow's peak is a dominant trait, meaning that if the child inherits the gene for this trait from one parent, that child will have a widow's peak regardless of the gene inherited from the other parent.

Answer:Monohybrid CrossIn a monohybrid cross, the parent organisms differ in a single characteristic. Suppose, for example, two humans have children. The father has a widow's peak and the mother does not. A widow's peak is a dominant trait, meaning that if the child inherits the gene for this trait from one parent, that child will have a widow's peak regardless of the gene inherited from the other parent.Consequently, there are two possibilities. The child could inherit the widow's peak gene from his father, or he could inherit the non-widow's peak gene from his father. He will inherit a non-widow's peak gene from its mother, who does not have the widow's peak gene. In this particular monohybrid cross, there is a fifty-fifty chance that any given child will have a widow's peak.

Answer:Monohybrid CrossIn a monohybrid cross, the parent organisms differ in a single characteristic. Suppose, for example, two humans have children. The father has a widow's peak and the mother does not. A widow's peak is a dominant trait, meaning that if the child inherits the gene for this trait from one parent, that child will have a widow's peak regardless of the gene inherited from the other parent.Consequently, there are two possibilities. The child could inherit the widow's peak gene from his father, or he could inherit the non-widow's peak gene from his father. He will inherit a non-widow's peak gene from its mother, who does not have the widow's peak gene. In this particular monohybrid cross, there is a fifty-fifty chance that any given child will have a widow's peak.Dihybrid CrossIn a dihybrid cross, the parents differ in two characteristics you want to study. The pattern of inheritance here is somewhat more complicated. Suppose, for example, that you have two parents, one of whom has dimples and a widow's peak while the other has no dimples and no widow's peak. Dimples, like a widow's peak, are a dominant trait. Consequently, if these two traits are not linked, each child has a 1/4 probability of inheriting dimples and widow's peak, a 1/4 probability of inheriting dimples but no widow's peak, a 1/4 probability of inheriting a widow's peak but no dimples, and a 1/4 probability of inheriting neither. Keep in mind, however, that linked traits might exhibit very different patterns.

Answer:

Light colored peppered moths decreases in number and dark colored peppered moths increases.

The population of light colored peppered moths decreases whereas the dark colored peppered moths increases in number because the light colored peppered moths are visible to the predator birds  whereas the dark colored peppered moths are not visible due to dark coating of the trees so they are saved from the birds and therefore, increase in population of dark colored peppered moths occurs and decrease occur in light colored peppered moths population.
