Suppose you have monohybrid pea plants in your garden and find that they produce round seed to wrinkled seeds in the ratio of 3: 1. if the allele are designated (r & r) respectively, what is the probable genotypes of the round seeds which were produced? a) rr & rrb) rr onlyc) rr & rrd) rr onlye) rr only

A) RR & Rr

Explanation:

In the given monohybrid cross, the obtained progeny expressed the round and wrinkled phenotype in 3:1 ratio respectively. Lets assume that the genotype of the parent plants was "Rr". A cross between Rr and Rr obtains progeny in following ratio=

Rr x Rr= 1/4 RR: 1/2 Rr: 1/4 rr.

Phenotype ratio= 3/4 round (1/4 RR and 1/2 Rr): 1/4 wrinkled (rr)

Therefore, the progeny with round seeds may be homozygous dominant (RR) or heterozygous dominant (Rr).

explanation:

i was told this before by a teacher, so yeah

the rocks are classified by the geological process they are formed by. the three main groups of rocks are igneous, metamorphic, and sedimentary. minerals are not they are classified under the chemical classes they are in. these groups include silicates, sulfates and carbonates.
