A plant biologist has been carrying out a long-term study of local buckwheat (chaparral plant) in southern California She has 20 years of data showing that a Buckwheat has a variable average leaf size of 4 cm, with some plants having larger leaves of up to 7 cm in width and some plants having smaller leaves, as small as 1 cm in width. She has noticed that over the last 5 years of drought, the average leaf width of buckwheat has decreased to 2.2 cm width. a. Tell me which type of selection is taking place?

b. Explain how you know?

c. Draw a line graph representing the population over the 15 years and the population after selection.

d. On a new graph like the one above, what would the population look like if there was disruptive selection?​

Please answer all the questions.

Nhumans, abo blood types refer to glycoproteins in the membranes of red blood cells. there are three alleles for this autosomal gene: ia, ib, and i. the ia allele codes for the a glycoprotein, the ib allele codes for the b glycoprotein, and the i allele doesn't code for any membrane glycoprotein. ia and ib are codominant, and i is recessive to both ia and ib. people with type a blood have the genotypes iaia or iai, people with type b blood are ibib or ibi, people with type ab blood are iaib, and people with type o blood are ii. if a woman with type ab blood marries a man with type o blood, which of the following blood types could their children possibly have? in humans, abo blood types refer to glycoproteins in the membranes of red blood cells. there are three alleles for this autosomal gene: ia, ib, and i. the ia allele codes for the a glycoprotein, the ib allele codes for the b glycoprotein, and the i allele doesn't code for any membrane glycoprotein. ia and ib are codominant, and i is recessive to both ia and ib. people with type a blood have the genotypes iaia or iai, people with type b blood are ibib or ibi, people with type ab blood are iaib, and people with type o blood are ii. if a woman with type ab blood marries a man with type o blood, which of the following blood types could their children possibly have? a, b, ab, and o ab and o a, b, and o a and b
