Answer:
Genotype
GGCuCu : GGCucu: GgCuCu: GgCucu : GGcucu: Ggcucu: ggCuCu: ggCucu: ggcucu
1 : 2: 4: 4: 2: 2: 2: 1
Phenotypic ration
Black & curled ears : Black & normal ears: Gray & curled ears : Grey & normal years
11: 4: 4: 1
Explanation:
Given -
Curled ears allele, Cu is dominant over an allele for normal ears , cu.
Also Black color (G) is dominant over allele for gray color (g)
Genotype of parent
gray cat homozygous for curled ears - ggCuCu
homozygous black cat with normal ears- GGcucu
offsprings produced were having genotype - GgCucu
Now cross is carried out between F1 progeny and these are as follows -
GgCucu * GgCucu

Answer:
b) negative reinforcement
Explanation:
Negative reinforcement has to do with rewarding or responding to a certain stimulus or behaviour by respond in a negative or averse manner.
Mary tries to change Pearl's behaviour by refusing to making a comment or responding to Pearl speaking her native language when she's capable of expressing herself in English. They do this so she would learn to speak English more and get used to it.
Pearl's family are using negative reinforcement to try and get her to speak English more often. If she uses her native language, she is ignored and not replied to unless she repeats her words in English. Ignoring her is the averse method her family is using to get her to respond to the stimulus of speaking English.
