The table below summarizes the traits that mendel examined during his experiments. traits studied by mendel a 3-column table labeled traits studies by mendel has 7 rows. column 1 has entries plant height, flower color, flower position, pod color, pod shape, seed color, seed shape. column 2 has entries tall, purple, end of stem, green, inflated, yellow, smooth. column 3 has entries short, white, middle of stem, yellow, constricted, green, wrinkled. what do these characteristics all have in common? they are all dominant. they can all be easily observed. they are all recessive. they can all be applied to other plants.

The answer is they are all easily observed

Explanation:

All the features shown in the table are easily observable. This characteristic was essential for Mendel to be able to create the foundations of genetics, which we still use today.

Mendel was an important geneticist who made great discoveries, such as how to transmit traits and other characteristics of genetic alleles.

Peas were chosen by Mendel for several factors, such as the ability to reproduce quickly, both sexually and asexual, as they have several characteristics that are easy to see and that are very specific, because they are cheap and possible to buy in pure lines.

the correct choice is i and iv.

the abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. the region occupied by the abdomen is termed the abdominal cavity. the stomach secretes acid and enzymes that digest food. ridges of muscle tissue called rugae line the stomach. the stomach muscles contract periodically, churning food to enhance digestion. the pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.
