Answer:
Cross an individual of the F1 with the purebred red flower, round pollen sweet pea parental.
Explanation:
The parental individuals are:
- PL/PL: purebred purple flower, long pollen sweet pea
- pl/pl: pure-bred red flower, round pollen sweet pea
The resulting F1 of the cross between the different parental types can only be PL/pl, which has purple flowers and long pollen. <u>This means that the purple flower (P) and long pollen (L) traits are dominant</u>.
To determine the recombination frequency between genes P/p and L/l, the cross should be done between a heterozygous individual for both genes (the F1) and a homozygous recessive individual for both traits (the pl/pl parental). <u>This is called a test cross.</u>
Answer:
Meiosis
Explanation:
All living organisms reproduce i.e. replicate themselves by producing young ones. However, they either do this sexually or asexually. Asexual reproduction involves the contribution of only one of the parent while sexual reproduction involves the two parent's contribution.
In sexual reproduction, a process of gamete formation called MEIOSIS occurs whereby the parental cell produces reproductive daughter cells that have a reduced number of chromosome (by half). The male and female gamete unites in sexual-reproducing organisms to form the offsprings.
Since only one parent is needed in asexual reproduction, there is no need for formation of gametes, hence, meiosis (a division only for reproductive cells) does not occur. The parent simply divides into its progeny.
Answer:
D- The code of chivalry by European knights
Explanation:
Bushido (武士道, "the way of the warrior") is a moral code concerning samurai attitudes, behavior and lifestyle. It is loosely analogous to the European concept of chivalry. There are multiple Bushido types which evolved significantly through history.
Answer: There are 206 bones in the human adult body, but 270 bones at birth.
I'm not sure if there are supposed to be answer choices to this, but I would assume the answer will be the genetic modification of crops.
