Answer:
In some mice, fur color is inherited through incomplete dominance. The colors that are possible are black fur, white fur and grey fur. Grey is the trait that is inherited through incomplete dominance. Scenario: a grey fur male mouse and a grey fur female mouse have 8 babies. The offspring that result are: 2 black fur, 5 grey fur and 1 white fur. But this is not what is statistically expected from that cross. Explain why this is still a probable outcome. This is as a result of mutation
Explanation:
Mutation is the sudden change of a gene, from the above explanation mating of an incomplete grey fur dominance with an incomplete grey fur dominance should not have had offspring with 2 black fur, 5 grey fur and white fur. Normal mating should have produced also an incomplete grey fur dominant offspring
Answer:
The genotype of the parents are not given. Let's try to answer this question generally. Let's assume the genotype of both parents to be Bb as genotype is not given.
Explanation:
B b
B BB Bb
b Bb bb
There is a 25% chance that the offspring will have BB genotype.
There is a 50% chance that the offspring will have Bb genotype.
There is a 25% chance that the offspring will have bb genotype.
There is a 75% chance that the offspring will have a dominant trait.
There is a 25% chance that the offspring will have recessive trait.
Phenotypic ratio will be 3:1
Answer:
Explanation:
Lower frequency for both dewlap extension and pushups. In the presence of predators and females an increase in the dewlap frequency and pushups is expected as a result of defense and breeding mechanisms mixed while in the second situation we have just breeding mechanisms involved
Answer:
25% type A, 25% type B, 25% type AB, 25% type O
If you put it into a punnett square:
B O
A AB AO
O BO OO
you get 25% for each phenotype
That's true heat and pressure causes rock forms to change.
