Answer:

There are several genetically modified species of plants that contain special proteins sequences in their genome to withstand freezing temperature. These have been developed by studying the CRG's (Cold Regulating Genes) in mustard plants living at freezing temperature. These proteins sequences are mostly similar in all protiens as studied in their genome and work like anti-Heat Shock proteins. All of these actions against cold are regulated by a hormone named Vernaline (A Type Of Gibberalins)

Varvara68 [4.7K]

Experts caution women with breast cancer or a history of this disease to limit their Soy food intake because it could stimulate cancer cells by closely imitating the actions of estrogen.

The breast cancer cells are taken out in a biopsy/surgery and gets tested to find if they have ample proteins which are estrogen or progesterone receptors.

The estrogen helps in stimulating hormone receptor-positive breast cancers to grow.

It is so because women get impacted by the diagnosis and treatment of early breast cancer. Whereas, personal fitness/diet reduces the risk of chronic disease, colon and breast cancers, diabetes, high blood pressure.

likoan [24]

Answer: Hello your question some missing data attached below is the complete question

answer:

P( first child having PKU ) 0.25 ≤ x ≤ 0.5

Explanation:

The pedigree father has PKU ( pp ) ( From the top right )

pedigree mother = PP

The possible resultant progeny = Pp

Resultant progeny marries non-carrier ( Pp x PP ) = PP , PP, pP, pP

Hence B is either ; PP ( non carrier ) or Pp ( carrier )

From left

one of the Resultant progeny = pp ( affected ). this simply means pedigree parents where both carriers or sufferers i.e. Pp or pp

Hence A is either ; Pp or pp

The probability of their first child having PKU

= PP x Pp = PP, Pp, PP, Pp ( probability = 0 in this case )

= Pp x Pp = PP, Pp, pP, pp ( probability = 1/4 * 100 = 25% )

= Pp x pp = Pp, Pp, pp, pp ( probability = 2/4 * 100 = 50% )

P( first child having PKU ) 0.25 ≤ x ≤ 0.5

lets denote dominant Gene = PP, recessive Gene = pp
