Round seeds (R) are dominant to wrinkled seeds (r), and yellow seeds (Y) are dominant to green seeds (y). A plant of unknown genotype is testcrossed to a true-breeding plant with wrinkled and green seeds. The offspring produced were 53 round and yellow, 49 round and green, 44 wrinkled and yellow, and 51 wrinkled and green. What is the likely genotype of the parent in question?

Explanation:

1. As given; Round seeds (R)  are dominant on wrinkled seeds (r),

Yellow seeds (Y) are dominant on green seeds (g).

In a testcross, between an unknown genotype and a homozygous recessive with wrinkled and green seeds (rryy).

offspring are:  

Round and yellow are  53; genotype (R_Y_)

round and green are  49;  genotype (R_yy)  

wrinkle and yellow are 44;  genotype (rrY_)

wrinkled and green are  51 ; genotype  (rryy)

Here, the genotype of parents of these offspring would be RrYy and rryy.

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community

explanation:

the principle of segregation describes how pairs of gene variants are separated into reproductive cells. from his data, mendel formulated the principle of segregation. we now know that the segregation of genes occurs during meiosis in eukaryotes, which is a process that produces reproductive cells called gametes.
