Please help me, I don't understand this
mihalych1998 [28]

Answer:

4, based on the assumption that the R allele is dominant over the r allele, and that the T allele is dominant over the t allele.

Explanation:

Any bush with a dominant petal color allele (R) will have red petals. This includes Rr and RR.

Any bush with a dominant bush size allele (T) will have a tall bush. This includes Tt and TT.

The only way to acquire a short bush or pink petals is to have two recessive alleles together (tt, rr).

RRTT, RrTT, RRTt, and RrTt -> red petals with tall bushes

RRtt, Rrtt -> Red petals with short bushes

rrTt, rrTT -> pink petals and tall bushes

rrtt-> pink petals with short bushes.

These are the four phenotype variations possible in this dihybrid cross.

balu736 [363]

Examining tumor tissue for driver mutations can help plan treatments that stop cancer cells from growing.

tumors was EGFR, followed by TP53 (18%), SETD2 (11%) and SMARCA4 (11%). More than 72% (81/112) of cases have mutations in at least one driver gene.

For example, the TP53 tumor suppressor gene is a driver gene, but it is only functional when both alleles of her TP53 gene are mutated. Furthermore, mutations can act as drivers only at certain stages of cancer.
