Answer:
The first male was bb Ee, and the second male was bb EE.
Explanation:
In Labradors coat colour is controlled by two genes. Suppose the two genes are B and E. B produces black colour and recessive form bb gives brown colour. Gene E is epistatic over gene B in its recessive form which means that ee will produce yellow colour regardless of the genotype present of B gene.
The first case is possible if the female lab is bbee (yellow) and the male lab is bbEe (brown):
bbee X bbEe
bE be
be bbEe bbee
So half of the offspring will be brown (bbEe) and half of them will be yellow (bbee)
The second case is possible if the same female bbee mates with a brown male of different genotype which can be bbEE:
bbee X bbEE
bE
be bbEe
So all offspring will be brown (bbEe)
Hence, the first male was bbEe and the second male was bbEE.
Kesav will Planting nitrogen-fixing crops, such as peas, in rotation with wheat crops can dramatically reduce the variability of farmers' income with a high-yield, high-protein harvest. ... Instead, they depend on the presence of nitrogen as ammonium or nitrate ions in the soil.
Answer:
The experimenter hypothesized that fertilizer would make the plants grow taller. The results show that, on average, plants with fertilizer grew 0.7 cm taller over the course of 12 days. This small amount of height increase could be attributed to the fertilizer or may be caused by natural differences in the plants.
Explanation:
Answer:
Approximately it will consume 55% of the total time in the interphase i.e. 800 minutes.
Explanation:
The time required in different phases are as follows:
It takes 800 minutes for interphase
It takes 400 minutes for prophase
It takes 120 minutes for metaphase
It takes 80 minutes for anaphase
It takes 40 minutes for telophase
Total -- 24 hours
From this it can be concluded that around 55% of the time spent in the interphase, whereas only 28% in the prophase, 8% time for metaphase, 6% Anaphase and 3% Telophase. This is all happens in the onion cell but in case of the human cell, prophase it takes about 15 min, in prometaphase it takes 15 mins, metaphase takes in about 20 min, Anaphase takes minimum of 3 min and telophase is about and cytokineses are about less then 10 mins.
