Jeffery Arnett is a physiologist who coined the term "emerging adulthood." This has previously been known as; delayed adulthood, transition age youth, youthhood, and the twixter years. He believes that the period between adolescence and adulthood is when the person reaches adulthood but doesn't have children, have sufficient funds, or have their own home. He believes it starts at 18 and ends around 25 years of age. He thinks this is when people are still looking for love, make money to spend on recreational activities, and trying to develop their own identities. This theory is highly controversial and has been contested by developmental psychologists.

If t=talk and t= short what will be the physical appearance of the offspring in the cross
qwelly [4]

Answer:

If T=tall and t=short, what will be the physical appearance of the offspring in the cross?

Explanation:

It looks like your question is incomplete, so I'll try to fill in the blanks.

The offspring will depend on the parents.  Each parent will need two alleles, so each parent would have to be TT (tall), Tt (tall) or tt (short--this is the only way to have a short individual).

Here are all the possible crosses:

TT X TT  = 100% TT (all tall)

TT X Tt = 50% TT, 50% Tt (all tall)

TT X tt = 100% Tt (all tall)

Tt X Tt = 25% TT (tall), 50% Tt (tall), 25% tt (short)

tt X tt = 100% tt (short)

Note that if there is a T present in the genotype (TT or Tt), that individual will be tall.  The only way to produce short offspring is for the both parents to have a copy of the short allele (t).
