The genealogy tree which is missing from the question is in the attachment.
Answer: 1) P1 =
; 2) P2 =
; 3)P3 = 
Explanation: 1) According to the genealogy tree, the individual III-3 has a P1 = 1/2, because each of the parents are heterozygous for the condition, since one of the ofspring is affected.
2) For individual III-4, one of the parents is heterozygous for the condition, so the probability of being a carrier is P2 = 1/2.
3) Now, for individual IV-1 be affected, the parents has to be carrier. So, this probability, depends on the probability of each parent being heterozygous and that the individual will be carrying the condition, which means:
P3 = 1/2 · 1/2 · 1/4 = 1/16.
The probability of having the condition is 1/16 or 6.25%.
Answer:
trend toward a sporophyte-dominated life cycle
the trend toward larger gametophytes
Explanation:
<em>The major trend in the evolution of land plants is the domination of the sporophytic phase in the life cycle and alternation of generation. It also moves towards a larger gametophytes</em>
In lower plants, the gameophyte phase was dominant in the life cycle while in bryophyte, both gametophyte and sporophyte phase are co-dependent.
The sporophyte phase is the diploid phase while the gametophyte phase is the haploid phase.
Also, the gameotyptic stages are quite microscopic (usually in the form of spores) in lower plants while they become bigger in land plants (in the form of ovary and pollen) although with fewer cells.
In cell biology a centriole is a cylindrical cellular organelle composed mainly of a protein called tubulin. Centrioles are found in most eukaryotic cells. A bound pair of centrioles, surrounded by a shapeless mass of dense material, called the pericentriolar material (PCM), makes up a structure called a centrosome.
