Answer:
The phenotypic ratio will be 3:1
Explanation:
As per this question there are two phenotypes for seed color, yellow and green. Both the parents are true breeding that means they are homozygous for this trait. Also, all the F1 plants have yellow seed color which clearly indicates that yellow seed color is a dominant trait while green is recessive trait.
The cross of true breeding plants as mentioned above is depicted as under:
Parents YY x yy
/ \ / \
F1 generation Yy Yy Yy Yy
So, as per the law of dominance because of the presence of Y allele, all these progeny will be yellow in color.
Next, when these F1 plants will be crossed, the result will be as under:
F1 generation Yy x Yy
/ \ / \
F2 generation YY Yy Yy yy
The genotypic ratio of F2 generation is 1:2:1
The phenotypic ratio of F2 generation is 3:1
It simply means that in F2 generation, 3 progeny which have allelic combination YY & Yy will be yellow colored while 1 progeny which has allelic combination yy will have green color.
Austin who was securely attached in Mary Ainsworth's theory of mother-infant attachment likely showed confidence in his caregiver's ability to protect him.
Options to this question were not provided. However, it is worthy to note that Mary Ainsworth's theory of mother-infant attachment classifies the relationship that children have with their caregivers as; Secure, Resistant, and Avoidant.
The Securely attached children are distressed when their mother is absent, they avoid strangers when their mother is not around but become friendly to strangers when their mothers are present.
They are also happy when their mother is around.
Generally, these sorts of children are confident and exhibit high self-esteem. So, Austin must have displayed some of these qualities.
