Answer:
Explanation:
A cross between plants with round seeds (RR) and plants with wrinkled seeds (rr). If both parents are homozygous, having one type of gamete each, i.e. R from round seed parent and r from wrinkled seed parent (RR X rr).
R R
r Rr Rr
r Rr Rr
All the offspring of generation would be round with genetic constitution Rr. They will be heterozygous plants having two different alleles.
If both parents has heterozygous round seeds with genotype Rr. So, we have Rr × Rr. The gametes produced from each of the parents are of two types, R and r.
R r
R RR Rr
r Rr rr
The generation has a genotypic ratio of 1 RR : 2 Rr : 1 rr. The phenotypic ratio is 3 round : 1 wrinkled.

Answer:
The same
Explanation:
Half life is the time taken for the number of atoms in a radioactive sample to decrease to half of the initial number of atoms. It is also the time taken for the activity of a radioactive sample to decrease to half of its original value.
If samples A and B were obtained from the same rock, then they contain the same number of atoms having the same initial activity even though the samples were not prepared in the same way for analysis.
Hence, samples A and B have the same half life.
