Answer:
all orange eyed
Explanation:
Mendelian genetics operate on the laws of segregation and independent assortment. This means that genes from either parent segregates independently and are separated into gametes at an equal frequency.
Since a cross between all the black-eyed cats and orange eyed cats lead to all black eyed cats. It is safe to assume that the black eye phenotype is dominant and the orange eye phenotype is recessive. If two orange eyed cat crossed then all the offspring would be orange eyed.
They can cause Down's syndrome or some other chromosomal disorder
Answer:
Experimental groups: type of dogs
Dependent variable: hearth rate
Independent variable: the amount of caffeine
Explanation:
The dependent variable is the variable being measured or tested in a given study, while the independent variable isn't changed by the other variables. In this case, the heart rate is dependent on the amount of caffeine, which is then the independent variable. The experimental groups are the groups exposed to the independent variable.
