Answer:
Rr x rr
Explanation:
Let's say
RR is a tall plant.
Rr is tall
& rr is a small plant
The only genotypes you can get to make two tall and two short is if you use a hetero pair and a same ressesive (rr) genes.
Explanation:
The inbreeding process, are blood crossings between relatives who have a common ancestor. Inbreeding leads to an increase in the frequency of homozygous genotypes and a decrease in the frequency of heterozygotes. We may also note that although changes in genotypic frequencies occur, no changes in allelic frequencies are observed over successive generations of self-fertilization. The main consequence of 2 individuals sharing one or more common ancestors is that they may carry replicas (identical copies) of one or more genes present in these ancestors. And if these individuals mate, they can pass on such replicas to their offspring, generating self-sibling offspring, that is, with two identical copies of the same gene that was present in these common ancestors.
Pond ecosystem considered as an open ecosystem because pond is always open . There is an interaction of pond with atmosphere , due to which it ecosystem becomes open.
