Lupe grows pea plants in her garden. the pea plants have flowers that can be either purple or white, with purple color being dominant to white color. the peas produced by lupe's pea plants can also be either round or wrinkled, with round peas being dominant to wrinkled peas. lupe crosses two pea plants that are heterozygous for both traits. if a gamete from this cross receives a dominant allele for flower color, how does this influence the probability of the gamete receiving a dominant allele for pea shape? (assume that the genes for flower color and pea shape follow the law of independent assortment.)

Answer-

Probability of the gamete receiving a dominant allele for pea shape if it has dominant allele for flower color is

Explanation-

Let "P" represents purple color and "p" represents white color.

While "R" represents round pea seed while "r" represents wrinkled pea seed

Genotype of parent with both heterozygous trait - PpRr

Possible genotypes are –

PpRR- 1

PpRr-4

pprr-1

Out of 16 possible genotype of offspring , 12 have dominant allele for flower color i.e "P"

Among these 12 pea plants, 9 have dominant allele for flower shape i.e "R"

Thus , probability of the gamete receiving a dominant allele for pea shape if it has dominant allele for flower color is

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:

fossil's are like over rated rocks like low key not gonna lie i don't get why we can't just call them old rocks like for real i mean i call my grandpa and grandma that smh
